Product Description

The SOUL Performance Exhaust System is a non-valved rear exhaust system developed for the 2025+ Porsche 992.2 GT3, replacing the restrictive factory rear muffler and eliminating Porsche's secondary valved exhaust path.

Rather than waiting for the factory valve programming to fully reveal the GT3's sound at higher engine speeds, the SOUL Performance Exhaust provides its full exhaust character throughout the entire rev range.

Exhaust flows from the factory headers through SOUL's specially designed cast transition cones, into 3-inch stainless-steel tubing, through a bespoke X-pipe, and finally exits through your choice of 4-inch exhaust tips.

Integrated Helmholtz resonators specifically target the GT3's approximately 3,400–4,000 RPM resonance range, helping control unwanted cabin drone while retaining the aggressive character of the naturally aspirated 4.0-liter flat-six.

SOUL also includes dedicated Valve Delete Modules, allowing the electronically controlled factory rear exhaust valves to be removed without generating valve-related check engine lights. SOUL Performance Products

NON-VALVED PERFORMANCE DESIGN:

The factory 992.2 GT3 uses electronically controlled exhaust valves to vary sound and exhaust routing.

Even with the factory exhaust placed into its more aggressive operating mode, Porsche's programming limits how much of the 4.0-liter engine's sound reaches the driver until higher in the rev range.

SOUL removes that secondary valved flow path entirely.

The Performance Exhaust therefore provides:

• Consistent exhaust character throughout the RPM range

• No factory valve intervention

• More sound during partial-throttle driving

• Stronger low- and mid-RPM engine character

• Immediate acoustic response to throttle input

• Maximum use of the GT3's naturally aspirated sound without replacing the factory headers

There is no quiet mode with this exhaust.

CAST TRANSITION CONES:

The factory GT3 header connection presents a relatively large opening that must transition into the rear exhaust tubing.

Rather than creating this transition from multiple welded sections or an abrupt reducer, SOUL developed dedicated cast transition cones.

The geometry was designed to create the least aggressive practical radius from the header flange into the rear exhaust.

The mating and clamping surfaces are then precision machined to provide an accurate seal.

Benefits include:

• Smoother exhaust-flow transition

• Reduced number of welded joints

• Increased durability

• Improved fitment consistency

• Cleaner transition into the 3-inch exhaust tubing

3-INCH X-PIPE EXHAUST:

After leaving the cast transitions, exhaust flows through 3-inch stainless-steel tubing into SOUL's bespoke X-pipe.

The X-pipe blends exhaust pulses from the opposing cylinder banks and contributes to the system's smoother, more cohesive flat-six sound.

The configuration is designed to produce a deeper, throatier character at lower RPM that builds into a considerably more aggressive naturally aspirated wail as engine speed increases. SOUL Performance Products

HELMHOLTZ ANTI-DRONE RESONATORS:

Early SOUL development identified noticeable resonance in approximately the:

3,400–4,000 RPM range

SOUL incorporated specially tuned Helmholtz resonators to target those frequencies.

Instead of simply adding a restrictive muffler to reduce sound everywhere, Helmholtz resonators target specific undesirable frequencies while allowing the primary exhaust flow to remain relatively unrestricted.

This helps provide:

• Reduced steady-state resonance

• More comfortable cruising

• Less undesirable cabin drone

• Retention of aggressive high-RPM sound

VALVE DELETE MODULES:

The Performance Exhaust physically removes the original Porsche rear exhaust valves.

Disconnecting those electronically monitored valves without addressing them can create vehicle faults.

SOUL therefore includes dedicated Valve Delete Modules.

The modules allow the factory valve hardware to be removed while preventing valve-removal-related check engine lights.

The exhaust itself remains permanently non-valved.

SOUND CHARACTER:

Expect:

• Throatier low-RPM sound

• Greater engine presence during normal driving

• More aggressive midrange character

• Much stronger flat-six sound under acceleration

• Increased high-RPM intensity

• Full exhaust sound without waiting for the factory valves to open

• A naturally aspirated flat-six wail approaching redline

• Controlled cabin resonance through the Helmholtz system

SOUL compares the overall volume to previous-generation 997 / 991 GT3 Center Muffler Bypass configurations rather than an extreme straight-pipe system. SOUL Performance Products

WITH FACTORY HEADERS:

The Performance Exhaust is specifically designed to work with the original Porsche header and catalyst assemblies.

With the factory headers retained:

• Factory catalytic converters remain installed

• Original emissions hardware remains upstream

• The modification is limited to the rear exhaust

• Exhaust sound increases substantially

• Factory rear-valve programming is eliminated

• Helmholtz resonators help maintain reasonable cabin presence

SOUL specifically states that retaining the factory headers means the Performance Exhaust itself does not alter the original upstream emissions equipment. SOUL Performance Products

WITH SOUL STREET HEADERS:

Pairing the Performance Exhaust with SOUL Street Headers creates a freer-flowing catted configuration.

This combination provides:

• High-flow performance catalysts

• Improved upstream exhaust flow

• Non-valved 3-inch rear exhaust

• Increased engine character

• Greater high-RPM sound

• Increased overall performance potential

WITH SOUL COMPETITION HEADERS:

Pairing the Performance Exhaust with SOUL Competition Headers creates a substantially more aggressive configuration.

Expect:

• Catless header architecture

• Maximum upstream exhaust flow

• Non-valved 3-inch rear exhaust

• Significantly increased exhaust volume

• Much stronger high-RPM character

• Competition-oriented sound and flow

Appropriate emissions and calibration requirements should be considered when replacing factory catalysts.

PERFORMANCE EXHAUST VS. VALVED EXHAUST:

Performance Exhaust

• Non-valved

• $4,075–$4,315 depending on tips

• 3-inch exhaust path

• X-pipe architecture

• Helmholtz resonators

• Full exhaust character throughout the RPM range

• No quiet mode

• Valve Delete Modules included

Valved Exhaust

• Retains electronic exhaust-valve operation

• Allows quieter and louder operating modes

• Better suited to customers prioritizing sound control

• Higher purchase price

The Performance Exhaust is the simpler and more aggressive rear-exhaust choice for customers who do not need factory-style sound control.

EXHAUST TIP OPTIONS:

The Performance Exhaust uses interchangeable 4-inch SOUL exhaust tips.

Two tip styles are available:

4" Slash Cut Single Wall

A more angular outlet with the end of the tip cut on a slant.

4" Straight Cut Single Wall

A traditional straight-cut circular exhaust outlet.

Each style is available in:

• Signature Satin

• Satin Black

This creates six total configurations.

EMISSIONS NOTE:

When installed with the original Porsche headers and catalytic converters, the SOUL Performance Exhaust replaces the rear muffler and valve assembly only.

Changing the headers or catalytic converters separately may affect emissions compliance.

Customers are responsible for determining compliance with applicable federal, state, and local regulations for their complete vehicle configuration.

Product Description

The SOUL Valved Exhaust System is designed for the 2025+ Porsche 992.2 GT3, delivering a substantial improvement in sound while retaining Porsche's factory electronic exhaust-valve operation.

SOUL replaces the factory rear muffler with a purpose-built system featuring smooth-radius cast transition cones, a bespoke X-chamber muffler for the valves-closed path, and a large-diameter 3-inch X-pipe for the valves-open path.

With the valves closed, exhaust is routed through a straight-through perforated muffler design that increases tone and presence without making the GT3 excessively loud during normal driving. As the valves progressively open, exhaust gains increasing access to the 3-inch X-pipe path for a smoother, higher-pitched, more aggressive flat-six sound.

The result is an OEM+ valved exhaust experience: noticeably more character during everyday driving, comfortable cabin presence, and a significantly stronger naturally aspirated wail as the 4.0-liter flat-six approaches the upper end of the rev range.

FACTORY ELECTRONIC VALVE INTEGRATION:

The 992.2 GT3 uses electronically actuated exhaust valves controlled by Porsche's factory ECU programming.

SOUL retains this functionality rather than replacing the valves with simulators or converting the exhaust to a permanently open configuration.

Under factory programming, the valves remain closed through much of the lower RPM range and begin progressively opening around approximately:

4,000 RPM

They reach their fully open position at approximately:

5,000 RPM

Even with Porsche Sport Exhaust activated, the factory ECU continues to control the valves according to its programmed strategy rather than simply leaving them permanently open.

The SOUL system works with this factory behavior while making both the valves-closed and valves-open operating states more engaging.

VALVES CLOSED:

With the valves closed, exhaust is directed through SOUL's bespoke muffled secondary flow path.

This path uses:

• Straight-through perforated tubing

• Surrounding acoustic packing

• An internal X-pipe

The design allows exhaust gases to continue flowing efficiently while reducing overall sound volume.

Compared with the factory system, the valves-closed character is:

• More pronounced

• Smoother

• More refined

• More mechanically engaging

• Less hollow in character

The increase in volume is intentionally moderate, making the system well suited to street use and longer-distance driving.

VALVES OPEN:

As the electronic exhaust valves open, exhaust gains access to the system's 3-inch primary flow path and external X-pipe.

This provides:

• Increased exhaust flow

• Greater overall volume

• Stronger high-RPM character

• More aggressive naturally aspirated sound

• Smoother blending between the two cylinder banks

• A higher-pitched GT-style exhaust note

SOUL intentionally designed the primary path aggressively because the secondary muffled path continues contributing to exhaust flow and acoustic control even when the valves are open.

This allows the system to produce considerably more character without requiring additional resonators or mufflers in the primary path.

DUAL X-PIPE ARCHITECTURE:

A key feature of the Valved Exhaust is the use of exhaust-bank blending in both operating paths.

With the valves open, the primary 3-inch X-pipe blends the left and right cylinder banks.

With the valves closed, an internal X-pipe within the muffler performs the same basic function for the secondary path.

This helps produce a smoother and more cohesive exhaust tone instead of allowing the two banks to sound completely isolated from one another.

CAST TRANSITION CONES:

The factory GT3 header outlet presents a large connection that must transition into the rear exhaust system.

SOUL developed dedicated cast transition cones to make this change in cross-section as smoothly as possible.

The cones use a gradual radius to promote efficient exhaust flow and are subsequently precision-machined at the mating and clamping surfaces for proper sealing.

Compared with constructing the transition from multiple welded pieces, the cast solution provides:

• Smoother internal geometry

• Fewer welded joints

• Greater consistency

• Improved durability

• Precise sealing surfaces

BESPOKE X-CHAMBER MUFFLER:

When the valves close, gases are routed through SOUL's dedicated muffler.

Instead of using a highly restrictive chambered design, SOUL uses straight-through perforated tubing surrounded by acoustic packing.

This allows exhaust energy to dissipate into the muffler packing while maintaining a relatively direct flow path.

The muffler also contains its own internal X-pipe, which blends both cylinder banks and contributes to the smoother exhaust character.

DRONE CONTROL:

The Valved Exhaust was specifically developed to maintain comfortable cabin acoustics.

The secondary muffled exhaust path helps control unwanted frequencies in the sub-3,000 RPM range, where resonance can become particularly noticeable during normal street driving.

Because some exhaust continues flowing through this secondary path even with the valves open, it also helps smooth the tone during more aggressive driving.

The result is a more present exhaust without the persistent booming or harshness common to simpler muffler-delete systems.

SOUND CHARACTER:

SOUL characterizes the system as a gentleman's OEM+ exhaust.

Expect:

• More exhaust presence during casual driving

• Increased mechanical flat-six tone

• Higher-pitched exhaust character

• Smoother bank-to-bank sound

• Refined valves-closed volume

• Comfortable cabin presence

• Progressive increase in aggression as the factory valves open

• Stronger naturally aspirated wail during high-RPM operation

• Moderate rather than extreme wide-open-throttle volume

This is designed for customers who want the GT3 to sound substantially more engaging without turning the car into a permanently loud track-style exhaust.

FACTORY VALVE PROGRAMMING:

Under factory control, the exhaust valves do not simply remain open whenever PSE is selected.

The factory strategy keeps the valves closed through much of the lower RPM range before progressively opening them between approximately 4,000 and 5,000 RPM.

Customers seeking 100% valve-open operation regardless of RPM or throttle condition will require an appropriate ECU calibration or compatible aftermarket valve controller.

The exhaust itself does not override Porsche's factory valve strategy.

WITH FACTORY HEADERS:

The SOUL Valved Exhaust can be installed while retaining the original Porsche headers and emissions equipment.

This configuration provides:

• Greater exhaust presence

• Retention of the factory catalysts

• Retention of factory electronic valve control

• Improved valves-closed sound

• More aggressive valves-open sound

• A straightforward rear-exhaust-only upgrade

This is the most conservative configuration for owners primarily interested in improving sound.

WITH SOUL STREET HEADERS:

Pairing the Valved Exhaust with SOUL Street Headers further reduces upstream exhaust restriction while retaining a catted configuration.

This combination provides:

• High-flow catalytic converters

• Improved header geometry

• Greater flat-six sound

• Increased exhaust-flow potential

• Full electronic rear-valve functionality

• Greater overall performance potential

WITH SOUL COMPETITION HEADERS:

Pairing the Valved Exhaust with SOUL Competition Headers creates a substantially more aggressive configuration.

This combination provides:

• Catless header architecture

• Maximum upstream exhaust flow

• Increased naturally aspirated sound

• Full 3-inch valves-open rear exhaust path

• Retained electronic exhaust-valve functionality

• Much stronger high-RPM character

Applicable emissions and ECU requirements should be considered when removing factory emissions components.

VALVED EXHAUST VS. PERFORMANCE EXHAUST:

Valved Exhaust

• Factory electronic valve control retained

• 3-inch valves-open path

• X-chamber muffled valves-closed path

• Quiet and aggressive operating ranges

• Higher level of everyday refinement

• Six exhaust-tip configurations

• $5,755–$5,995

Performance Exhaust

• Non-valved

• Factory exhaust valves removed

• 3-inch X-pipe architecture

• Helmholtz resonators

• Full exhaust character throughout the RPM range

• Valve Delete Modules included

• Six exhaust-tip configurations

• $4,075–$4,315

The Valved Exhaust is the better choice for customers who want more sound while retaining Porsche's factory-controlled exhaust-volume functionality.

EXHAUST TIP OPTIONS:

The Valved Exhaust accepts SOUL's interchangeable 4-inch single-wall exhaust tips.

Two styles are available:

4" Slash Cut Single Wall

An angled outlet for a more aggressive appearance.

4" Straight Cut Single Wall

A traditional straight-cut circular outlet.

Each style is available in:

• Signature Satin

• Brushed

• Satin Black

This creates six total combinations.

EMISSIONS NOTE:

When installed with the original Porsche headers and catalytic converters, the SOUL Valved Exhaust replaces the rear muffler assembly only and does not itself remove the factory upstream catalytic converters.

Installation of separate aftermarket headers or catalyst components may alter emissions compliance.

Customers are responsible for determining compliance with all applicable federal, state, and local regulations for their complete vehicle configuration.

Product Description

The SOUL Valved Exhaust Package is a complete header-back exhaust system for the 2025+ Porsche 992.2 GT3, combining long-tube performance headers with SOUL's electronically controlled Valved Exhaust System.

Rather than simply replacing the rear muffler, this package addresses the entire exhaust path from the cylinder heads rearward. SOUL removes the restrictive factory header assemblies, catalyst and particulate-filter hardware, and enormous factory rear-muffler connection, replacing them with long-tube runners, precision CNC-machined merge collectors, interchangeable catted or catless sections, V-band connections, and a purpose-built valved rear exhaust.

With the valves open, exhaust flows through a large-diameter 3-inch X-pipe for maximum flow and a sharper, higher-pitched flat-six sound. With the valves closed, gases are routed through a secondary flow path and bespoke SOUL X-chamber muffler, substantially reducing cabin presence while maintaining a smoother and more engaging tone than the factory exhaust.

Customers can choose between a Competition / Catless configuration for maximum flow and track-oriented sound or a Catted configuration for reduced exhaust volume and a lower likelihood of emissions-related diagnostic faults.

COMPLETE HEADER-BACK EXHAUST:

The Valved Exhaust Package replaces substantially more of the exhaust system than SOUL's standalone Valved Exhaust.

The package includes:

Long-Tube Performance Headers

and

SOUL Valved Rear Exhaust System

This eliminates the restrictive factory header architecture and allows SOUL to optimize the exhaust system as one complete assembly.

The result is greater exhaust-flow capability, substantially increased flat-six character, and a more cohesive transition between the headers and rear exhaust.

LONG-TUBE HEADERS:

Replacing the factory headers is central to the package.

The original Porsche system incorporates restrictive emissions hardware and an exceptionally large rear-muffler connection, forcing compromises in exhaust-runner geometry and flow.

SOUL replaces this architecture with long-tube runners feeding precision-machined merge collectors.

The performance-oriented header design improves:

• Exhaust flow

• Exhaust scavenging potential

• High-RPM breathing

• Throttle response

• Flat-six sound

• Overall performance potential

CNC-MACHINED MERGE COLLECTORS:

The individual header runners converge through SOUL's precision-machined merge collectors.

The collectors are designed to combine exhaust pulses smoothly while maintaining exhaust-gas velocity.

On the naturally aspirated 4.0-liter GT3 engine, collector geometry is especially important because exhaust scavenging and pulse timing directly influence response and high-RPM breathing.

SOUL manufactures the billet 304L stainless components using 5-axis CNC machining for accurate internal geometry and strength.

V-BAND CONNECTIONS:

The factory Porsche system uses an extremely large approximately 7 5/8-inch connection point at the rear muffler.

SOUL's header design eliminates this architecture and replaces the older-style Porsche connection arrangement with more efficient V-band connections.

Benefits include:

• Improved component alignment

• Cleaner exhaust transitions

• Easier servicing

• Secure sealing

• Elimination of costly factory clamp and donut-gasket hardware

VALVES OPEN:

With the electronic exhaust valves open, gases flow through:

3-inch piping

and a dedicated:

X-pipe

The X-pipe merges exhaust pulses from both cylinder banks, helping create a smoother and more cohesive exhaust note.

Expect:

• Maximum rear-exhaust flow

• Significantly greater exhaust volume

• Sharper throttle-related sound

• Higher-pitched flat-six character

• Stronger mechanical presence

• Aggressive high-RPM wail

• Considerably greater excitement at wide-open throttle

VALVES CLOSED:

With the valves closed, exhaust is redirected through a secondary flow path and SOUL's bespoke muffler.

The muffler uses straight-through perforated tubing surrounded by acoustic packing rather than forcing gases through an aggressively restrictive chambered design.

An internal X-pipe continues blending both cylinder banks.

This configuration provides:

• Reduced exhaust volume

• Lower cabin presence

• Smoother exhaust tone

• Reduced resonance below approximately 3,000 RPM

• Comfortable touring characteristics

• More refined sound than a permanently open exhaust

• Greater character than the factory system

FACTORY ELECTRONIC VALVE CONTROL:

The 992 GT3 uses electronically actuated exhaust valves.

These valves cannot simply be disconnected or allowed to hang freely because the actuators themselves maintain tension on the mechanical valve bodies.

SOUL's included hardware preserves proper actuator operation.

Factory programming generally operates the valves as follows:

Below approximately 4,000 RPM:
Valves closed

Approximately 4,000–5,000 RPM:
Valves progressively opening

Approximately 5,000 RPM and above:
Valves fully open

For customers who want the exhaust valves commanded completely open at wide-open throttle regardless of RPM, an appropriate ECU calibration can modify the factory valve strategy.

CATTED CONFIGURATION:

The Catted Valved Exhaust Package adds high-flow catalytic-converter sections downstream of the long-tube headers.

This configuration provides:

• Long-tube performance headers

• High-flow catalytic converters

• 3-inch valves-open rear exhaust

• Factory electronic valve functionality

• Reduced sound compared with the catless configuration

• Lower likelihood of catalyst-related check engine lights

• Greater street-oriented refinement

The catalysts are positioned after the headers using carefully routed tubing designed to maintain exhaust velocity despite the limited available space beneath the GT3.

COMPETITION / CATLESS CONFIGURATION:

The Competition configuration eliminates the catalytic converters completely.

This provides:

• Maximum available header flow

• Maximum exhaust volume

• Maximum high-RPM character

• Reduced exhaust-system weight

• Maximum naturally aspirated flat-six presence

• Track-oriented exhaust configuration

SOUL states that the Competition configuration weighs approximately 17 lbs less than the comparable factory exhaust system.

Because the factory catalytic converters are removed, the Competition configuration may trigger a check engine light.

SOUL recommends an appropriate custom ECU calibration to address emissions-related diagnostic faults for track use.

INTERCHANGEABLE CATTED / CATLESS SECTIONS:

An important benefit of the package is that the catalyst sections are modular.

The catted and catless sections are interchangeable, allowing the exhaust configuration to be changed later without replacing the complete header and rear-exhaust assembly.

This allows an owner to run:

• Catted sections for lower volume and reduced CEL potential

or

• Catless sections for maximum track-oriented sound and flow

using the same underlying exhaust architecture.

SOUND CHARACTER:

The system was developed to provide greater sound quality rather than simply maximizing volume.

Expect:

• Greater presence during casual driving

• Smoother low-RPM tone

• Higher-pitched flat-six character

• Reduced hollow character compared with the factory exhaust

• Comfortable cruising below approximately 4,000 RPM

• Noticeable difference between valves-open and valves-closed operation

• Aggressive wide-open-throttle sound

• Strong naturally aspirated wail as RPM increases

• Significantly greater sound with the Competition configuration

The valved design provides substantially greater flexibility than a permanently open muffler-less exhaust.

DRONE CONTROL:

Packaging a complete high-flow exhaust underneath the GT3 while maintaining acceptable touring comfort required SOUL to incorporate a dedicated muffled secondary path.

The muffler is designed to reduce resonance in the sub-3,000 RPM range, where steady-state cruising can otherwise produce undesirable cabin boom.

Because the muffled path uses straight-through perforated tubing and an internal X-pipe, sound attenuation is achieved without introducing an unnecessarily restrictive exhaust route.

EXHAUST TIP OPTIONS:

The Valved Exhaust Package uses a modular tip plate allowing the exhaust-tip assemblies to be changed independently of the rest of the exhaust.

Two styles are available:

4" Slash Cut Single Wall

An angled outlet with a more aggressive appearance.

4" Straight Cut Single Wall

A traditional straight-cut circular outlet.

Each style is offered in:

• Signature Satin

• Brushed

• Satin Black

This produces six tip configurations for each catalyst choice.

Customers are responsible for determining compliance with all applicable federal, state, and local regulations.

Product Description

The SOUL Race Exhaust System is a complete header-back exhaust system developed for the 2025+ Porsche 992.2 GT3, engineered for maximum naturally aspirated performance, substantial weight reduction, and an aggressive motorsport-inspired exhaust note.

Rather than simply replacing the rear muffler, SOUL replaces the complete exhaust path from the cylinder heads rearward. Long-tube runners and 5-axis CNC-machined merge collectors optimize exhaust flow before feeding interchangeable catted or catless sections and a full 3-inch rear exhaust with an X-pipe.

The X-pipe blends exhaust pulses from both cylinder banks to produce a smoother, higher-pitched character reminiscent of Porsche's GT racing cars. The system eliminates the factory rear muffler and electronically controlled exhaust valves, with included Valve Delete Modules allowing the original valves and actuators to be removed without triggering valve-related faults or the associated 6,000 RPM reduced-rev condition.

The Competition / Catless system weighs approximately 42.9 lbs, compared with approximately 68.2 lbs for the comparable factory exhaust components, saving approximately 25.3 lbs / 11.4 kg. The catted system weighs approximately 47.6 lbs, saving approximately 20.6 lbs / 9.3 kg.

COMPLETE HEADER-BACK RACE SYSTEM:

The Race Exhaust replaces substantially more of the GT3 exhaust than a conventional rear-muffler system.

The package includes:

Long-Tube Performance Headers

Interchangeable Catted or Catless Sections

Full 3-Inch X-Pipe Rear Exhaust

Valve Delete Modules

4-Inch Exhaust Tips

This allows the entire exhaust path to be engineered as one complete system rather than compromising around the factory header and rear-muffler architecture.

LONG-TUBE HEADERS:

The factory 992.2 GT3 header assemblies must balance performance with emissions, production, packaging, durability, and regulatory requirements.

These compromises limit:

• Primary-runner length

• Runner diameter

• Collector geometry

• Exhaust scavenging

• High-RPM flow

SOUL replaces the factory manifolds with longer, smoother-flowing runners designed around performance rather than mass-production constraints.

On the high-revving 4.0-liter naturally aspirated engine, header geometry has a direct influence on exhaust-pulse behavior, response, and high-RPM breathing.

CNC-MACHINED MERGE COLLECTORS:

Rather than using simple slip-on collectors, SOUL developed a bespoke billet merge collector.

The collector is designed digitally and manufactured using CNC machining to provide:

• Controlled runner convergence

• Optimized merge angles

• Improved exhaust-gas velocity

• Precise geometry

• Reduced opportunity for leakage

• Greater structural durability

The billet design also allows SOUL to maximize primary-runner length while eliminating multiple fabricated weld joints.

V-BAND CONNECTIONS:

The factory exhaust terminates into an exceptionally large approximately 7 5/8-inch connection at the rear muffler.

SOUL eliminates this arrangement along with the older clamp and donut-gasket interface.

The Race Exhaust instead uses V-band connections for:

• Precise component alignment

• Secure sealing

• Cleaner exhaust transitions

• Easier servicing

• Simplified installation and removal

FULL 3-INCH REAR EXHAUST:

After the catalyst or Competition sections, exhaust enters a full:

3-inch flow path

SOUL avoids unnecessary reductions in pipe diameter to maintain exhaust velocity and maximize available flow.

The rear exhaust is intentionally simple and performance focused, eliminating the heavy dual-entry factory muffler and its varying internal exhaust diameters.

X-PIPE DESIGN:

After the interchangeable catalyst section, the exhaust enters SOUL's X-pipe.

The crossover is designed to maximize blending between the two cylinder banks while minimizing reductions in effective exhaust diameter.

This blending produces:

• Smoother exhaust tone

• Higher-pitched character

• Stronger motorsport sound

• Greater acoustic cohesion between both cylinder banks

• Aggressive high-RPM wail

The result is significantly different from simply running two independent straight exhaust paths.

COMPETITION / CATLESS CONFIGURATION:

The Competition configuration completely eliminates the catalytic converters.

This provides:

• Maximum available exhaust flow

• Maximum naturally aspirated sound

• Lowest system weight

• Maximum high-RPM character

• Most aggressive throttle-related sound

• Greatest performance potential

• Approximately 42.9-lb total system weight

• Approximately 25.3 lbs / 11.4 kg of weight savings

Because the factory catalytic converters are removed, this configuration may generate emissions-related diagnostic faults and is intended for appropriate competition applications.

CATTED CONFIGURATION:

The catted Race Exhaust retains high-flow catalytic sections within the same modular exhaust architecture.

This provides:

• High-flow performance catalysts

• Reduced exhaust volume compared with the Competition configuration

• Same long-tube header architecture

• Same full 3-inch rear exhaust

• Same X-pipe

• Same Valve Delete Modules

• Same exhaust-tip options

• Approximately 47.6-lb system weight

• Approximately 20.6 lbs / 9.3 kg of weight savings

The catted sections can be exchanged for Competition sections later without replacing the complete exhaust.

MODULAR CATALYST SECTIONS:

One of the major advantages of the Race Exhaust is its modular construction.

The catted and catless sections are interchangeable.

This allows the owner to change between:

Catted configuration

and

Competition / Catless configuration

while retaining the same headers, rear exhaust, X-pipe, and exhaust tips.

This makes the system particularly useful for vehicles that may see both different track configurations and evolving future modifications.

VALVE DELETE MODULES:

The factory GT3 electronic exhaust valves cannot simply be unplugged and removed.

Doing so creates an electronic fault and can place the vehicle into a reduced operating mode with an approximately:

6,000 RPM rev limit

SOUL includes dedicated Valve Delete Modules with the Race Exhaust.

The modules connect to the factory valve wiring and electronically simulate the expected valve operation.

This allows:

• Factory exhaust valves to be removed

• Factory valve actuators to be removed

• No valve-related check engine light

• No valve-related 6,000 RPM reduced-rev condition

The physical exhaust remains permanently non-valved.

SOUND CHARACTER:

The Race Exhaust is one of SOUL's most aggressive 992 GT3 systems.

Expect:

• Substantially increased flat-six sound

• Greater engine presence throughout the rev range

• Sharper throttle-related response

• Higher-pitched exhaust tone

• Stronger mechanical character

• Aggressive naturally aspirated wail

• Very high exterior volume

• Cup Car / RSR-inspired character

• No factory exhaust-valve intervention

• No quiet mode

SOUL describes the volume as being on the extreme end for a street-driven vehicle.

Customers prioritizing daily-driving refinement and adjustable sound should consider the SOUL Valved Exhaust Package instead.

PERFORMANCE:

SOUL publishes Dynojet testing performed by Hydra Motor Works for the Race Exhaust architecture.

Race Exhaust System Alone:

• Approximately +23 whp peak

• Approximately +19 lb-ft peak torque

• Additional gains through the midrange and at maximum RPM

With a Hydra Motor Works Stage 2 ECU calibration, SOUL reports:

• Approximately +60 whp peak

• Approximately +26 lb-ft peak torque

• Maximum gains exceeding 60 whp

• Maximum torque gains exceeding 70 lb-ft at portions of the power curve

The larger tuned figures represent the combined exhaust and ECU-calibration configuration, not exhaust-only gains.

WEIGHT SAVINGS:

Comparable Factory Exhaust Components:
Approximately 68.2 lbs / 30.9 kg

SOUL Competition / Catless Race Exhaust:
Approximately 42.9 lbs / 19.5 kg

Competition Weight Savings:
Approximately 25.3 lbs / 11.4 kg

SOUL Catted Race Exhaust:
Approximately 47.6 lbs / 21.6 kg

Catted Weight Savings:
Approximately 20.6 lbs / 9.3 kg

The Competition system removes approximately 37% of the weight of the comparable factory exhaust components.

RACE EXHAUST VS. HIGH PITCH EXHAUST:

Race Exhaust

• Catted or catless configurations

• Full 3-inch rear exhaust

• X-pipe architecture

• Six interchangeable tip combinations

• Modular catalyst sections

• Traditional aggressive GT / Cup Car sound

• Maximum flexibility

High Pitch Exhaust

• Fixed catless configuration

• Reverse-megaphone acoustic tuning

• Dual 2.5-inch to single 3-inch architecture

• Dedicated single 3D-printed outlet

• Specifically engineered toward a higher-frequency sound

• No catalyst or tip options

The Race Exhaust offers substantially more configuration flexibility, while the High Pitch system is a specialized acoustic design.

RACE EXHAUST VS. VALVED EXHAUST PACKAGE:

Race Exhaust

• Non-valved

• Full 3-inch rear exhaust

• Catted or catless

• Maximum volume

• Valve Delete Modules

• Approximately 20.6–25.3 lbs lighter than comparable factory components

• Track-focused character

Valved Exhaust Package

• Retains factory electronic valve operation

• 3-inch valves-open path

• Muffled valves-closed path

• Catted or catless

• Greater cruising refinement

• Better suited to customers requiring adjustable volume

EXHAUST TIP OPTIONS:

Two 4-inch single-wall tip styles are available:

4" Slash Cut Single Wall

An angled exhaust outlet with a more aggressive appearance.

4" Straight Cut Single Wall

A conventional straight-cut circular exhaust outlet.

Each tip style is available in:

• Signature Satin

• Brushed

• Satin Black

This creates six tip choices per catalyst configuration and twelve total sellable variants.

CHECK ENGINE LIGHT:

The included Valve Delete Modules address diagnostic faults caused by removal of the factory electronic exhaust valves.

They do not eliminate emissions-related diagnostic faults caused by removal or replacement of the factory catalytic converters.

SOUL states that the product may trigger a check engine light due to removal of the factory catalytic converters.

An appropriate ECU calibration may therefore be required depending on catalyst configuration, vehicle specification, and intended use.

EMISSIONS / COMPETITION USE NOTE:

The SOUL Race Exhaust replaces factory emissions-related exhaust components.

The Competition configuration completely eliminates the catalytic converters, while the catted configuration replaces the factory catalyst assemblies with aftermarket high-flow components.

The system is not CARB certified and SOUL specifies it for closed-course competition use only.

Customers are responsible for determining compliance with all applicable federal, state, and local regulations before installation or use.

Product Description

The SOUL High Pitch Exhaust System is a complete header-back exhaust system engineered for the Porsche 992 GT3 platform to create a sharper, more exotic, motorsport-derived flat-six soundtrack that becomes increasingly intense as the engine approaches redline.

Rather than simply increasing exhaust volume, SOUL engineered the entire exhaust path around acoustic tuning. The system removes the restrictive factory catalyst assemblies, particulate-filter sections, and oversized factory rear-muffler connection, replacing them with optimized headers, reverse megaphones, dual 2.5-inch exhaust paths, and a single 3-inch final flow path.

Carefully calculated exhaust lengths and merge geometry move the sound toward a higher frequency while maintaining exhaust velocity and flow. At the rear, gases exit through a distinctive 3D-metal-printed single outlet, giving the High Pitch Exhaust a dedicated motorsport appearance rather than using conventional dual bolt-on tips.

The complete system weighs approximately 35.9 lbs, compared with approximately 68.2 lbs for the equivalent factory exhaust components, saving an impressive 32.3 lbs / 14.6 kg.

F1-INSPIRED HIGH-PITCH SOUND:

The High Pitch Exhaust differs fundamentally from a conventional muffler-delete or louder rear exhaust.

SOUL designed the complete system around frequency manipulation.

The goal is not simply maximum volume—it is to move the exhaust note upward in frequency and create a sharper, more exotic sound as engine speed increases.

This is achieved through the combination of:

• Full exhaust-system replacement

• Optimized header geometry

• Reverse megaphones

• Dual 2.5-inch exhaust paths

• Carefully controlled tube lengths

• A merge into a single 3-inch flow path

• Purpose-built single rear outlet

As the GT3's naturally aspirated 4.0-liter engine approaches redline, the system develops an increasingly aggressive and motorsport-inspired tone.

REVERSE MEGAPHONES:

After the headers, exhaust gases enter specially engineered reverse megaphone sections.

Megaphone geometry has long been used in motorsport exhaust systems to manipulate exhaust-wave behavior and acoustic characteristics.

SOUL uses reverse megaphones as part of the High Pitch system's overall acoustic strategy, helping shift the exhaust tone toward the sharper frequency range that distinguishes this exhaust from its other GT3 systems.

DUAL 2.5-INCH TO SINGLE 3-INCH FLOW PATH:

After leaving the headers, the two cylinder banks travel through separate:

2.5-inch exhaust paths

These merge into a single:

3-inch exhaust path

The length of this transition is carefully calculated to tune exhaust frequency while maintaining efficient gas velocity and flow.

This architecture is a major reason the High Pitch Exhaust sounds fundamentally different from SOUL's conventional Performance, Valved, and Race Exhaust configurations.

FACTORY CONNECTION ELIMINATION:

The High Pitch system eliminates the factory GT3's extremely large 7 5/8-inch connection point at the rear muffler assembly.

SOUL also revised the header flange and connection architecture to eliminate the older Porsche-style connection requiring OEM clamps and donut gaskets.

The system instead uses a more efficient V-band connection, providing:

• Cleaner assembly

• Improved exhaust-flow transition

• Easier servicing

• Precise component alignment

• A more purpose-built complete-system architecture

SINGLE 3D-PRINTED OUTLET:

Unlike SOUL's other 992 GT3 exhaust systems, the High Pitch Exhaust does not terminate in conventional interchangeable dual exhaust tips.

Instead, the exhaust exits through a dedicated single 3D-metal-printed outlet.

The outlet is digitally engineered to:

• Integrate cleanly into the GT3 bumper surround

• Provide a motorsport-inspired appearance

• Maintain the system's single 3-inch exhaust architecture

• Minimize heat transfer into nearby bodywork

Because the outlet is an integral component of the High Pitch Exhaust, there are no separate tip style or finish options for this system.

VALVE DELETE MODULES:

The High Pitch Exhaust removes the Porsche factory rear muffler and exhaust valves entirely.

Simply disconnecting the factory electronic valves can create diagnostic faults.

SOUL therefore includes dedicated Valve Delete Modules.

These modules electronically mirror the expected factory valve signals, allowing the ECU to recognize the valve system as operating normally even though the physical valves have been removed.

This allows the High Pitch Exhaust to operate as a permanently unrestricted non-valved system without creating valve-specific check engine lights.

NON-VALVED DESIGN:

The High Pitch Exhaust has:

• No factory rear muffler

• No electronic exhaust valves

• No quiet exhaust path

• No selectable tip configuration

The system operates through its dedicated high-pitch performance path at all times.

Customers seeking factory-style control over exhaust volume should consider SOUL's Valved Exhaust System instead.

SOUND CHARACTER:

Expect:

• Dramatically increased naturally aspirated flat-six sound

• Sharper exhaust tone

• Increasingly exotic character as RPM rises

• Much stronger high-RPM intensity

• More motorsport-oriented exhaust frequencies

• Greater mechanical engine presence

• Immediate response to throttle input

• Distinctive single-outlet sound character

• No factory valve intervention

• No quiet mode

The High Pitch system is specifically intended for customers seeking a more exotic, race-derived sound rather than simply a louder version of the factory exhaust.

WEIGHT SAVINGS:

Comparable Factory Exhaust Components:
Approximately 68.2 lbs / 30.9 kg

SOUL High Pitch Exhaust System:
Approximately 35.9 lbs / 16.3 kg

Weight Savings:
Approximately 32.3 lbs / 14.6 kg

That represents approximately a 47% reduction in exhaust-system weight compared with the factory components being replaced.

• Available catted or catless

• Multiple bolt-on exhaust-tip styles and finishes

• More conventional aggressive GT3 exhaust character

• Greater configuration flexibility

The High Pitch Exhaust is the more specialized choice for customers prioritizing a distinctive high-frequency motorsport sound.

EUROPEAN-SPEC VEHICLES:

SOUL specifies that the High Pitch Exhaust also fits European-specification vehicles.

However, European vehicles must be paired with an appropriate:

• OBD solution

or

• ECU calibration

to eliminate resulting emissions-related check engine lights.

This requirement is separate from the included Valve Delete Modules, which address the removal of the factory exhaust valves.

EMISSIONS / COMPETITION USE NOTE:

The SOUL High Pitch Exhaust removes the factory catalytic-converter and particulate-filter assemblies.

This product is not CARB certified and SOUL specifies it for closed-course competition use only.

Removal of factory emissions-control equipment may violate regulations governing vehicles operated on public roads.

Customers are responsible for determining compliance with all applicable federal, state, local, and international regulations before installation or use.

LONG-TUBE HEADER DESIGN:

Even Porsche's GT3 exhaust system must balance performance against emissions, manufacturing, packaging, sound, and regulatory requirements.

The factory header assembly houses dense catalytic-converter and particulate-filter hardware close to the engine. This limits how freely the exhaust manifold can be optimized strictly around:

• Primary-runner length

• Runner diameter

• Collector efficiency

• Exhaust-gas velocity

• High-RPM flow

SOUL's Competition Headers remove those packaging compromises and replace the factory assemblies with a dedicated performance header.

CNC-MACHINED MERGE COLLECTOR:

SOUL designs the Competition Headers around a billet CNC-machined merge collector rather than relying on a basic convergence of fabricated primary tubes.

The merge collector helps smoothly combine the individual exhaust pulses while maintaining gas velocity as they enter the downstream exhaust.

On the GT3's naturally aspirated engine, this architecture is particularly important because header geometry directly influences exhaust scavenging, throttle response, midrange behavior, and high-RPM breathing.

FACTORY REAR EXHAUST COMPATIBILITY:

The Competition Headers are specifically designed as a direct replacement for the factory headers while retaining the stock rear exhaust system. SOUL Performance Products

This allows owners to retain:

• Factory rear muffler

• Factory electronic exhaust valves

• Factory exhaust tips

• Porsche's original rear-exhaust packaging

while substantially reducing restriction farther upstream.

SOUND CHARACTER:

Removing the factory catalyst and particulate-filter assemblies produces a significant increase in the amount of naturally aspirated flat-six character reaching the rear exhaust.

Expect:

• Greater mechanical engine sound

• Stronger flat-six exhaust presence

• Increased sound throughout the rev range

• Sharper throttle-related sound

• More aggressive high-RPM character

• Greater difference as the factory rear exhaust valves open

• Significant amplification of whichever rear exhaust system is installed downstream

With the stock rear muffler retained, the final result remains more controlled than a complete SOUL Race Exhaust.

THROTTLE RESPONSE & PERFORMANCE:

SOUL developed the Competition Headers to improve flow, response, tone, and power potential from the 992 GT3's 4.0-liter engine. SOUL Performance Products

Reducing the restriction created by the original catalyst and particulate-filter assemblies gives exhaust gases a freer path away from the cylinders and allows the engine to breathe more efficiently at high RPM.

SOUL does not currently publish a standalone horsepower or torque figure for this header set, so specific power gains should not be assumed.

COMPETITION HEADERS VS. STREET HEADERS:

CHECK ENGINE LIGHT / ECU CALIBRATION:

The Competition Headers remove the factory catalytic converters and particulate-filter hardware.

SOUL's current 992.2 Competition Header page does not publish a definitive no-CEL claim or specify a universal ECU-calibration requirement.

Because factory emissions components are removed, emissions-related diagnostic behavior can depend on vehicle specification and calibration.

Customers should confirm the appropriate calibration strategy for their intended vehicle and use before installation.

EMISSIONS / COMPETITION USE NOTE:

The SOUL Competition Headers remove factory catalytic converters and particulate-filter hardware.

These components are not CARB certified and may not be legal for use on emissions-controlled vehicles operated on public roads.

Customers are responsible for determining compliance with applicable federal, state, and local regulations before installation or use.

Product Description

The SOUL Street Headers are designed for 2025+ Porsche 992.2 GT3 and GT3 Touring owners looking to improve exhaust flow, throttle response, power potential, and flat-six sound while retaining a catted exhaust configuration.

Even on Porsche's motorsport-derived 4.0-liter naturally aspirated flat-six, the factory header assemblies must accommodate catalytic converters, particulate-filter hardware, packaging requirements, noise regulations, and emissions targets. These requirements limit primary-runner geometry, collector efficiency, and overall exhaust flow.

SOUL replaces the restrictive factory header assemblies with a performance-oriented design built around large-diameter, free-flowing catalytic converters, optimized runners, and precision-machined billet 304L stainless steel head flanges.

The result is a freer path from the cylinder heads into the downstream exhaust, improving engine response while allowing substantially more of the GT3's naturally aspirated character to reach the rear exhaust system.

WHY UPGRADE THE FACTORY HEADERS?

The 992.2 GT3's factory exhaust must satisfy requirements extending far beyond outright performance.

The original header assembly incorporates emissions hardware close to the engine, including catalytic-converter and particulate-filter sections. Packaging those components within the exhaust restricts how freely Porsche can optimize:

• Primary-runner length

• Runner geometry

• Exhaust flow

• Collector efficiency

• Sound

• Overall performance

SOUL's Street Headers remove those packaging compromises and replace the factory assemblies with a performance-focused catted header system.

LARGE-DIAMETER HIGH-FLOW CATALYTIC CONVERTERS:

Unlike SOUL Competition Headers, the Street Headers retain catalytic converters.

SOUL builds the system around large-diameter, free-flowing performance catalysts designed to reduce exhaust restriction compared with the factory header assemblies while maintaining a catted configuration.

This provides a middle ground between the original Porsche exhaust and SOUL's completely catless Competition Headers.

BILLET 304L CNC HEAD FLANGES:

SOUL uses billet 304L stainless steel head flanges precision machined on a 5-axis CNC machine.

The flange design creates a more controlled transition from the cylinder-head exhaust ports into the header runners while increasing strength in one of the exhaust system's most highly stressed areas.

Repeated track use subjects the headers to extreme heat cycles and vibration. The billet construction is designed to reduce the likelihood of cracking while maintaining accurate sealing and runner alignment.

EXHAUST FLOW & THROTTLE RESPONSE:

The Street Headers are engineered to reduce restriction between the engine and downstream exhaust system.

Improved runner geometry and freer-flowing catalysts allow exhaust gases to leave the cylinders more efficiently.

SOUL specifically targets improvements in:

• Exhaust flow

• Throttle response

• Power potential

• Naturally aspirated engine character

• High-RPM breathing

The effect is particularly relevant on the GT3's high-revving 4.0-liter engine, where exhaust-system efficiency and scavenging play an important role in engine response.

SOUND CHARACTER:

Replacing the restrictive factory header assemblies allows significantly more of the GT3's natural flat-six sound to reach the rear exhaust.

Expect:

• Greater naturally aspirated flat-six presence

• Increased mechanical engine character

• Stronger exhaust tone under load

• Greater high-RPM intensity

• Sharper response to throttle inputs

• Amplification of the sound characteristics of the rear exhaust installed downstream

The exact final sound depends heavily on the rear exhaust.

With the factory rear muffler retained, the vehicle remains more restrained than one equipped with a SOUL Performance, Valved, or Race rear exhaust.

WITH FACTORY REAR EXHAUST:

The Street Headers can be installed while retaining the original Porsche rear exhaust.

This provides:

• Improved upstream exhaust flow

• Increased engine character

• Greater exhaust sound

• Improved throttle response

• Retention of the factory rear muffler

• Retention of the factory rear exhaust-valve functionality

This makes the Street Headers suitable as a standalone first-stage performance upgrade.

WITH SOUL REAR EXHAUST:

The Street Headers can also be paired with compatible SOUL 992.2 GT3 rear exhaust systems.

Combining freer-flowing headers with a less restrictive rear exhaust further increases:

• Overall exhaust sound

• High-RPM character

• Exhaust-flow capability

• Mechanical engine feedback

• Performance potential

The final system configuration can therefore be tailored around the customer's desired balance between refinement and sound.

STREET HEADERS VS. COMPETITION HEADERS:

Street Headers

• Retain performance catalytic converters

• More street-oriented configuration

• Reduced restriction compared with factory

• Increased flat-six sound

• Improved throttle response

• $5,695.00

Competition Headers

• Catless

• Maximum available header flow

• More aggressive sound

• More competition-focused configuration

• Lower purchase price

The Street Headers are the appropriate option for customers who want upgraded header geometry and flow while retaining catalytic converters.

992.1 / 992.2 COMPATIBILITY:

SOUL uses the same manufacturer part number for its 992.1 and 992.2 GT3 Street Headers.

The 992.2 receives its own dedicated product listing, but the underlying SOUL part remains the same.

EMISSIONS NOTE:

The SOUL Street Headers retain aftermarket performance catalytic converters but replace the original Porsche header and emissions assemblies.

They are not CARB certified.

Retaining catalytic converters does not necessarily make an aftermarket header legal for road use in every jurisdiction.

Customers are responsible for determining compliance with applicable federal, state, and local regulations before installation or use.

Product Description

The SOUL Performance Exhaust System is a complete non-valved turbo-back exhaust solution developed specifically for the 2026+ Porsche 992.2 911 Turbo S T-Hybrid, engineered to dramatically increase exhaust flow, performance, turbocharger sound, and overall engine character.

SOUL replaces the restrictive factory catalytic converters, Gasoline Particulate Filters, and valved rear exhaust architecture with a substantially freer-flowing system featuring a minimum 3.5-inch exhaust path from the turbochargers back, compared with approximately 2.75 inches on the factory system.

At the center of the exhaust is SOUL's advanced XY-pipe, developed through extensive digital flow analysis, 3D scanning, metal additive manufacturing, and nine physical design revisions. Instead of simply crossing the two exhaust banks like a conventional X-pipe, the XY-pipe incorporates a shared center chamber with carefully calculated merge and bypass passages to blend the banks and produce a smoother, more refined, higher-pitched turbocharged flat-six exhaust note.

Integrated Helmholtz anti-drone chambers target the platform's natural 2,000–2,500 RPM resonance range, allowing the system to deliver significantly more sound and flow without sacrificing highway comfort.

Two configurations are available: a high-flow catted Performance Exhaust designed around untuned factory-ECU integration, and a Competition Exhaust that eliminates the catalytic converters for maximum flow and requires ECU calibration. SOUL Performance Products

3.5-INCH TURBO-BACK DESIGN:

The factory 992.2 Turbo S exhaust averages approximately:

2.75 inches

SOUL increases the exhaust path to a minimum of:

3.5 inches from the turbochargers back

This substantial increase in cross-sectional area provides additional flow capacity for the high-output T-Hybrid powertrain and reduces downstream restriction.

The larger exhaust path is designed to support:

• Increased exhaust-gas flow

• Improved turbocharger efficiency

• Reduced post-turbine restriction

• Stronger engine response

• Increased performance on factory software

• Additional headroom for ECU calibration and future power upgrades

The electrically assisted turbocharger architecture helps the engine take advantage of these large flow cross sections without the traditional response penalty associated with oversized conventional turbocharger systems. SOUL Performance Products

T-HYBRID TURBO ARCHITECTURE:

SOUL applied its development experience from the 992.2 Carrera GTS T-Hybrid platform to Porsche's significantly more powerful 992.2 Turbo S twin-turbo T-Hybrid system.

The electrically assisted turbochargers dramatically reduce the time required to develop boost pressure.

This allows Porsche to use unusually large exhaust-flow cross sections while maintaining rapid torque delivery.

Despite this potential, the factory system forces exhaust through restrictive catalytic converters and large GPF assemblies.

SOUL's Performance Exhaust reduces those downstream restrictions to better utilize the Turbo S powertrain's available exhaust-flow capability.

OPTIMIZED XY-PIPE:

One of the most significant engineering features of the system is SOUL's proprietary XY-pipe.

During development, keeping the two exhaust banks completely separated created an undesirable harsh, tractor-like sound.

A conventional X-pipe smoothed the tone, but SOUL continued development.

Using detailed 3D scans, digital flow simulations, additive manufacturing, thousands of miles of road testing, and nine design revisions, SOUL developed the final XY-pipe.

Instead of merely crossing the two banks, the XY-pipe incorporates:

• A shared central chamber

• Carefully calculated merge sections

• Dedicated bypass passages

• Controlled communication between the two exhaust banks

The result is a more thoroughly blended exhaust note that SOUL describes as robust, smooth, refined, and higher-pitched. SOUL Performance Products

3D-PRINTED 316L CONSTRUCTION:

SOUL uses its in-house metal additive manufacturing capabilities for several of the most complex portions of the exhaust.

The following sections are 3D printed from 316L stainless steel:

• XY-pipe

• Exhaust inlet sections

• Exhaust tip sections

Metal 3D printing allows internal flow paths and acoustic features to be created that would be extremely difficult to reproduce using conventional bent and welded tubing.

This manufacturing process is particularly important to the complex internal geometry of the XY-pipe.

HELMHOLTZ ANTI-DRONE SYSTEM:

Increasing exhaust diameter and removing factory sound attenuation can easily produce undesirable cabin resonance.

SOUL identified inherent drone frequencies in approximately the:

2,000–2,500 RPM range

Dedicated Helmholtz anti-drone canisters are tuned specifically around these frequencies.

The chambers target undesirable sound frequencies without forcing exhaust through a restrictive muffler.

SOUL reports that the resulting cabin character remains refined enough for comfortable highway conversation without the reverberation, harshness, buzzing, or booming typically associated with an aggressive aftermarket turbo-back exhaust. SOUL Performance Products

SOUND CHARACTER:

The Performance Exhaust is designed to provide significantly more character without sacrificing refinement.

Expect:

• Significantly increased turbocharger sound

• Stronger turbo spool and whistle

• Greater turbocharged flat-six presence

• Smooth, blended exhaust tone

• Higher-pitched character than separated exhaust-bank designs

• Increased exterior volume under acceleration

• Tasteful burbles during deceleration

• Stronger mechanical feedback

• Controlled highway cruising volume

• Minimal objectionable drone

SOUL describes the system as capable of remaining relatively understated during cruising while becoming dramatically more noticeable when the accelerator is pressed.

PERFORMANCE / DYNO RESULTS:

SOUL independently dyno-tested its development 992.2 Turbo S at Vollux Autowerks using the high-flow catted Performance Exhaust and 93-octane pump fuel.

With hardware changes only, SOUL reports maximum gains exceeding:

+100 lb-ft of torque around 2,500 RPM

and approximately:

+55 wheel horsepower

+45 lb-ft of torque

at approximately 6,300 RPM.

These gains were recorded without aftermarket ECU software.

SOUL notes that factory torque-management programming limits some of the potential midrange gains. Additional calibration can therefore take greater advantage of the increased exhaust-flow capacity. SOUL Performance Products

HIGH-FLOW CATTED PERFORMANCE EXHAUST:

The catted configuration is the primary Performance Exhaust System.

It incorporates SOUL-designed high-flow catalytic converters featuring:

• Custom-specified precious-metal catalyst coating

• Triple-metal-matrix core construction

• Increased exhaust-flow capacity

• Full 3.5-inch minimum turbo-back architecture

• Removal of the restrictive factory GPF assemblies

• Factory oxygen-sensor locations

SOUL engineered the system to replicate factory GPF pressure differentials and oxygen-sensor behavior, helping minimize the potential for a check engine light on an otherwise untuned vehicle.

This should be understood as an engineered CEL-mitigation strategy rather than an unconditional no-CEL guarantee. SOUL Performance Products

COMPETITION / CATLESS EXHAUST:

For customers seeking maximum exhaust flow, SOUL also offers a Competition configuration with no catalytic converters.

The Competition system provides:

• Completely catless architecture

• Factory GPF removal

• Minimum 3.5-inch turbo-back flow path

• Maximum available exhaust flow

• Maximum turbocharger sound

• Greatest weight reduction

• Most aggressive exhaust character

• Additional performance headroom for tuned applications

An ECU tune is required to run the Competition configuration.

SOUL explicitly specifies the tune requirement for the catless version. SOUL Performance Products

VALVE DELETE MODULES:

The factory 992.2 Turbo S uses exhaust valves within the side muffler assemblies.

Because the SOUL Performance Exhaust is permanently non-valved, those factory valves and mufflers are removed.

SOUL includes dedicated Valve Delete Modules with the system.

These modules prevent the removal of the factory side-muffler valves from generating valve-related check engine lights.

No exhaust-valve functionality remains—the Performance Exhaust operates through its unrestricted performance path at all times.

WEIGHT SAVINGS:

The comparable factory exhaust components weigh approximately:

73 lbs / 33.1 kg

The SOUL Performance / Catted Exhaust weighs approximately:

47.6 lbs / 21.6 kg

Approximate catted weight savings:

25.4 lbs / 11.5 kg

The SOUL Competition / Catless Exhaust weighs approximately:

43 lbs / 19.5 kg

Approximate catless weight savings:

30 lbs / 13.6 kg

The Competition version therefore removes approximately 41% of the comparable factory exhaust-system weight.

SOUL describes the overall reduction as roughly 30 lbs depending on configuration. SOUL Performance Products

Product Description

The SOUL Competition Exhaust System is the most aggressive complete exhaust solution for the 992.2 Porsche 911 Carrera GTS T-Hybrid platform, combining SOUL's catless Competition Downpipe with its full 3.5-inch non-valved rear exhaust system.

The factory GTS exhaust routes gases from Porsche's electrically assisted turbocharger through an extremely restrictive catalytic converter and large Gasoline Particulate Filter before entering the factory valved rear exhaust. SOUL removes this entire architecture, eliminating the catalytic converter, GPF, rear muffling, and factory exhaust valves to create a substantially freer-flowing turbo-back system.

Exhaust diameter increases from approximately 2.75 inches on the factory system to 3.5 inches from the turbo back, providing significantly greater flow capacity for the T-Hybrid's high-output eTurbo powertrain.

An integrated Helmholtz anti-drone chamber targets the platform's inherent 2,200–2,800 RPM resonance range, helping control unwanted cabin drone and rasp despite the system's completely catless, non-valved design.

The result is maximum turbocharger sound, substantially increased exhaust volume, reduced post-turbine restriction, and the greatest exhaust-flow potential of SOUL's current 992.2 Carrera GTS systems.

COMPLETE CATLESS TURBO-BACK DESIGN:

The Competition Exhaust replaces the entire exhaust system beginning immediately downstream of the electrically assisted turbocharger.

The package combines:

SOUL Competition Downpipe

with

SOUL 3.5-Inch Performance Rear Exhaust

The Competition Downpipe eliminates the factory catalytic converter and particulate filter entirely, while the rear section removes the factory muffler and electronic exhaust valves.

The result is SOUL's least restrictive complete exhaust configuration for the 992.2 Carrera GTS.

T-HYBRID / eTURBO ARCHITECTURE:

The 992.2 Carrera GTS uses Porsche's T-Hybrid powertrain with a single electrically assisted exhaust-gas turbocharger.

An electric motor integrated into the turbocharger allows the turbine to accelerate extremely quickly, helping Porsche combine large exhaust-flow cross sections with rapid boost response.

Without the electrical assistance, an exhaust and turbocharger system capable of flowing this amount of gas would traditionally produce significantly more lag.

SOUL's Competition Exhaust is designed to take advantage of this architecture by dramatically reducing restriction downstream of the eTurbo.

FACTORY GPF & CATALYST RESTRICTION:

Despite the T-Hybrid powertrain's substantial exhaust-flow capability, the factory system forces exhaust gases through a large GPF and restrictive catalytic converter immediately after the turbocharger.

SOUL describes this section as one of the most restrictive exhaust components it has encountered on a performance vehicle.

The Competition Exhaust completely eliminates both restrictions.

This creates a substantially freer path from the eTurbo through the remainder of the exhaust system.

COMPETITION DOWNPIPE:

The included Competition Downpipe provides the most aggressive upstream exhaust configuration SOUL offers for the 992.2 GTS.

It features:

• No catalytic converter

• No GPF

• Maximum post-turbine flow

• Purpose-built 3D-printed 316L stainless turbo inlet

• .065-inch-wall T304L stainless construction

• Significantly increased turbocharger sound

• Reduced post-turbine restriction

• Approximately 15.9 lbs of weight savings from the downpipe assembly alone

The Competition Downpipe weighs approximately 11.5 lbs, compared with approximately 27.4 lbs for the factory downpipe assembly.

FULL 3.5-INCH REAR EXHAUST:

After the Competition Downpipe, exhaust continues through a full 3.5-inch rear exhaust system.

The factory exhaust averages approximately 2.75 inches in diameter.

Increasing the complete turbo-back system to 3.5 inches provides significantly greater cross-sectional flow area and additional capacity for:

• Increased exhaust flow

• Reduced backpressure

• Improved turbocharger efficiency

• Tuned engine applications

• Higher-output future builds

• Additional fueling and turbocharger upgrades

NON-VALVED PERFORMANCE DESIGN:

The factory 992.2 Carrera GTS uses electronically controlled exhaust valves that continuously alter exhaust flow depending on engine operating conditions.

SOUL eliminates the valves entirely.

The Competition Exhaust therefore operates through its unrestricted 3.5-inch performance path at all times.

There is:

• No quiet mode

• No factory valve intervention

• No muffled secondary exhaust path

• No restriction associated with the factory rear muffler

This system is intended for customers prioritizing maximum flow and an aggressive driving experience rather than factory-style sound control.

HELMHOLTZ ANTI-DRONE SYSTEM:

A completely catless 3.5-inch exhaust has the potential to create substantial low-frequency resonance.

SOUL identified the 992.2 GTS's inherent drone frequencies around approximately:

2,200–2,800 RPM

and incorporated a tuned Helmholtz chamber into the system.

The chamber targets these frequencies without substantially restricting the main exhaust path.

The goal is to maintain the Competition Exhaust's aggressive character while reducing the unpleasant resonance and rasp that can occur with simpler straight-pipe exhaust designs.

SOUND CHARACTER:

The Competition Exhaust is intended to provide a constant, highly engaging turbocharged soundtrack.

Expect:

• Dramatically increased turbocharger spool

• Much greater boost sound

• Significantly increased exhaust volume

• Deep turbocharged flat-six growl

• Greater mechanical character

• Stronger sound throughout the RPM range

• Added volume during deceleration

• No factory exhaust-valve intervention

• No quiet exhaust mode

• Active cabin presence

• Helmholtz-controlled highway resonance

The unequal-length factory exhaust manifolds give the 992.2 Carrera GTS a different character from Porsche's naturally aspirated GT3 engines.

Rather than attempting to replicate a high-pitched GT3 sound, SOUL developed the exhaust around the GTS's naturally deeper, turbocharged character—more reminiscent of a modern interpretation of a classic 930 Turbo growl.

PERFORMANCE:

SOUL has demonstrated substantial performance potential from reducing exhaust restriction on the 992.2 Carrera GTS.

Testing of SOUL's high-flow catted Performance Exhaust System produced:

More than +50 wheel horsepower

More than +40 lb-ft of torque

on factory ECU software.

Those dyno results were obtained with the high-flow catted version, not this catless Competition Exhaust.

The Competition Exhaust removes even more downstream restriction, but SOUL does not currently publish a separate Competition Exhaust dyno result.

The +50 whp / +40 lb-ft figures should therefore not be represented as measured Competition Exhaust gains.

ECU TUNE REQUIRED:

An ECU tune is mandatory with the SOUL Competition Exhaust System.

The Competition Exhaust completely removes both the factory catalytic converter and GPF.

SOUL explicitly states that:

• A check engine light will occur without appropriate calibration

• An ECU tune is mandatory

This is a requirement rather than an optional performance recommendation.

CHECK ENGINE LIGHT:

Because the Competition Exhaust eliminates the factory catalyst and particulate-filter system, the vehicle's factory diagnostic strategy will recognize the missing emissions hardware.

A check engine light should therefore be expected without appropriate ECU calibration.

Unlike SOUL's high-flow catted system, the Competition Exhaust does not incorporate catalyst or GPF-monitoring provisions intended for untuned factory ECU operation.

COMPETITION VS. PERFORMANCE EXHAUST:

Competition Exhaust System

• $6,495

• Catless Competition Downpipe

WEIGHT SAVINGS:

SOUL publishes a clear weight comparison for the included Competition Downpipe:

Factory Downpipe: approximately 27.4 lbs

SOUL Competition Downpipe: approximately 11.5 lbs

Downpipe Weight Savings: approximately 15.9 lbs / 7.2 kg

SOUL does not currently publish a complete factory-vs.-Competition-Exhaust weight comparison for the entire turbo-back system.

For that reason, only the verified 15.9-lb downpipe weight reduction should be advertised rather than estimating the total system savings.

EMISSIONS / COMPETITION USE NOTE:

The SOUL Competition Exhaust completely removes the factory catalytic converter and Gasoline Particulate Filter.

SOUL specifies the system as intended for off-road use only.

An ECU tune is mandatory.

Removal of factory emissions-control equipment may violate regulations governing vehicles operated on public roads.

Customers are responsible for determining compliance with all applicable federal, state, local, and international regulations.

Product Description

The SOUL Competition Downpipe is designed specifically for the 992.2 Porsche 911 Carrera GTS T-Hybrid platform, eliminating the restrictive factory catalytic converter and Gasoline Particulate Filter for maximum post-turbo exhaust flow, response, turbocharger sound, and performance potential.

The factory GTS forces exhaust leaving Porsche's electrically assisted turbocharger through a massive GPF and restrictive catalytic converter. SOUL replaces this assembly with a lightweight, unrestricted downpipe engineered around the T-Hybrid's exceptionally high exhaust-flow capability.

A purpose-designed 3D-printed 316L stainless steel turbo inlet optimizes the transition immediately downstream of the eTurbo, while mandrel-bent .065-inch-wall T304L stainless steel tubing provides the durability required for demanding street and track environments.

The Competition Downpipe weighs approximately 11.5 lbs, compared with approximately 27.4 lbs for the factory assembly, removing an impressive 15.9 lbs / 7.2 kg from the exhaust system. SOUL Performance Products

T-HYBRID / eTURBO ARCHITECTURE:

The 992.2 Carrera GTS uses Porsche's electrically assisted exhaust-gas turbocharger rather than a conventional turbocharger arrangement.

The integrated electric motor allows the turbocharger to reach operating speed extremely quickly, which lets Porsche use large exhaust-flow cross sections without suffering the turbo lag that would normally accompany them.

This gives the T-Hybrid system tremendous exhaust-flow potential.

SOUL identified the factory exhaust hardware immediately downstream of the eTurbo as a major restriction preventing the system from fully taking advantage of that potential. SOUL Performance Products

FACTORY GPF & CATALYST RESTRICTION:

After leaving the eTurbo, exhaust gases must pass through an exceptionally restrictive factory emissions assembly.

SOUL describes the factory configuration as using a massive approximately 8-inch GPF in addition to the catalytic converter.

This combination severely restricts exhaust flow immediately downstream of the turbocharger.

The Competition Downpipe removes both restrictions completely, creating the least restrictive downpipe configuration SOUL offers for the 992.2 Carrera GTS. SOUL Performance Products

CATLESS COMPETITION DESIGN:

Unlike SOUL's Sport Cat Downpipe, the Competition Downpipe contains no catalytic converter.

There is also no GPF.

Removing these components provides:

• Maximum post-turbine flow

• Minimum downpipe restriction

• Maximum turbocharger sound

• Greatest downpipe weight reduction

• Stronger throttle and engine response

• Maximum performance potential for tuned applications

This is SOUL's most aggressive downpipe configuration for the T-Hybrid GTS.

3D-PRINTED 316L TURBO INLET:

SOUL uses metal additive manufacturing for the critical inlet section immediately downstream of the eTurbo.

The inlet is 3D printed from 316L stainless steel, allowing its internal geometry to be optimized specifically around exhaust flow.

Metal 3D printing gives SOUL much greater freedom over internal shape than conventional cut-and-weld fabrication and allows the transition away from the turbocharger to be engineered as a smooth, purpose-built component. SOUL Performance Products

TURBO RESPONSE / DRIVABILITY:

Removing the restrictive factory catalytic converter and GPF allows exhaust gases to leave the eTurbo much more efficiently.

SOUL reports:

• Better response under all operating conditions

• A noticeably harder pull throughout the power curve

• Greater turbocharger sound

• Increased exhaust volume

The improvement becomes particularly significant on a tuned vehicle capable of taking advantage of the Competition Downpipe's substantially increased flow capacity. SOUL Performance Products

SOUND CHARACTER:

SOUL reports that changing the downpipe produces a larger transformation in sound than replacing the factory valved rear exhaust alone.

Expect:

• Dramatically increased turbocharger sound

• Much greater boost volume

• More audible turbo spool

• Stronger flat-six character

• Increased mechanical sound

• Greater exhaust volume under load

• Noticeable sound increase with the factory valves open

• More subtle increase with the valves closed

Despite the significant increase in sound, SOUL reports that undesirable cabin presence remains very low across the different factory valve modes.

Cold starts are also only mildly affected because the valves close almost immediately after startup. SOUL Performance Products

WITH FACTORY VALVED EXHAUST:

The Competition Downpipe can be installed while retaining the original Porsche rear exhaust.

This provides:

• Maximum downpipe flow

• Significantly increased turbocharger sound

• Major reduction in exhaust restriction

• Retention of factory exhaust-valve control

• More controlled overall volume than pairing the downpipe with a non-valved rear exhaust

The factory rear exhaust therefore remains a viable option for customers wanting the flow benefits of the Competition Downpipe while retaining Porsche's valve-controlled rear muffler.

WITH SOUL VALVED EXHAUST:

Pairing the Competition Downpipe with the SOUL Valved Exhaust System creates a significantly more aggressive turbo-back configuration while retaining electronic valve control.

This combination provides:

• Catless maximum-flow downpipe architecture

• Increased turbocharger sound

• Reduced exhaust restriction

• 3-inch valves-open rear exhaust path

• Factory PSE integration

• Quieter valves-closed cruising capability

An appropriate ECU calibration remains mandatory because the Competition Downpipe removes the catalytic converter and GPF.

WITH SOUL PERFORMANCE EXHAUST:

The Competition Downpipe can form the basis of an even more aggressive performance-oriented setup when combined with an appropriate freer-flowing rear exhaust.

The reduced restriction of the catless downpipe provides additional headroom for tuned or higher-output applications.

SOUL reports gains exceeding 50 wheel horsepower and 40 lb-ft of torque from its complete 992.2 GTS Performance Exhaust System on factory software and states that the majority of those gains result from improved efficiency in the catalyst/downpipe section.

Those figures are for the complete SOUL Performance Exhaust and should not be interpreted as isolated Competition Downpipe gains. SOUL Performance Products

ECU TUNE REQUIRED:

An ECU tune is mandatory when installing the SOUL Competition Downpipe.

Because the factory catalytic converter and GPF are completely removed, the vehicle will detect the missing emissions hardware.

SOUL explicitly states that:

• A check engine light will occur without appropriate tuning

• An ECU tune is mandatory to operate this component correctly

This should not be presented as an optional recommendation.

CHECK ENGINE LIGHT:

A check engine light should be expected if the Competition Downpipe is installed without an appropriate ECU calibration.

Unlike the SOUL Sport Cat Downpipe, which incorporates engineering intended to mimic factory GPF monitoring behavior, the Competition Downpipe completely removes the factory catalyst and GPF hardware.

The Competition Downpipe therefore requires an ECU calibration capable of properly accounting for the changed exhaust configuration. SOUL Performance Products

WEIGHT SAVINGS:

Factory Downpipe Assembly:
Approximately 27.4 lbs / 12.4 kg

SOUL Competition Downpipe:

Weight Savings:
Approximately 15.9 lbs / 7.2 kg

That represents approximately a 58% reduction in downpipe assembly weight.

The Competition Downpipe also saves approximately 5.25 lbs more than SOUL's Sport Cat Downpipe, which weighs approximately 16.75 lbs.

COMPETITION DOWNPIPE VS. SPORT CAT DOWNPIPE:

Competition Downpipe

• Completely catless

• No factory GPF

• Maximum exhaust flow

• Maximum turbocharger sound

• Approximately 11.5 lbs

For customers prioritizing maximum flow, weight reduction, and tuned performance, the Competition Downpipe is the more aggressive option.

For customers prioritizing easier integration and retaining a catalyst, the Sport Cat Downpipe is the more street-oriented configuration.

EMISSIONS / COMPETITION USE NOTE:

The SOUL Competition Downpipe completely removes the factory catalytic converter and Gasoline Particulate Filter.

SOUL specifies this product as intended for off-road use only.

An ECU tune is mandatory.

Removing factory emissions-control equipment may violate regulations governing vehicles operated on public roads.

Customers are responsible for determining compliance with all applicable federal, state, local, and international regulations before installation or use.

Product Description

SOUL Performance Products' Valved Exhaust Package is a complete turbo-back exhaust upgrade for the Porsche 992.2 Carrera GTS T-Hybrid platform, combining the SOUL Sport Cat Downpipe with the SOUL Valved Exhaust System for substantial improvements in exhaust flow, performance, turbo sound, and overall exhaust character.

The factory 992.2 GTS exhaust system must satisfy increasingly strict global emissions and sound regulations, resulting in a highly restrictive downpipe incorporating a large gasoline particulate filter and catalytic converter. SOUL replaces this assembly with its high-flow Sport Cat Downpipe featuring a purpose-designed 300-cell catalytic converter and optimized exhaust routing.

SOUL reports gains of 40+ wheel horsepower from the complete Valved Exhaust Package, with the majority of the improvement coming from the significant reduction in restriction at the downpipe.

The rear exhaust is replaced with SOUL's Valved Exhaust System, featuring an enlarged 3-inch valves-open flow path compared with the factory 2.75-inch system. An integrated high-flow harmonic-dampening resonator helps control undesirable frequencies while preserving a substantially more aggressive exhaust note when the valves open.

The result is a complete exhaust system that delivers stronger response, greater turbo presence, a richer exhaust note, and significantly more sound when desired while retaining a refined valves-closed mode for everyday driving.

Fitment

Fits 2025+ Porsche 992.2 911 GTS T-Hybrid models worldwide, including:

SOUL Sport Cat Downpipe

The Sport Cat Downpipe addresses one of the largest restrictions in the factory 992.2 GTS exhaust system.

The factory downpipe incorporates a large GPF assembly and restrictive catalytic converter immediately downstream of the electrically assisted turbocharger. SOUL eliminates the factory GPF restriction and replaces the catalytic section with a purpose-designed high-flow catalyst.

Key features include:

• SOUL-designed 300-cell catalytic converter

• Custom-specified precious-metal catalyst coating

• Triple metal matrix catalyst core

• Removes the restrictive factory GPF section

• Engineered provisions for factory GPF pressure monitoring

• 316L stainless-steel 3D-printed turbo inlet

• Increased exhaust flow

• Improved engine response

• Stronger acceleration throughout the power curve

• Increased turbocharger sound

• Approximately 16.75 lbs compared with 27.4 lbs for the factory downpipe

• Approximately 10.65 lbs of downpipe weight savings

SOUL specifically engineered the system around factory GPF pressure differentials and oxygen-sensor behavior to help minimize the potential for a check engine light on otherwise stock-software vehicles.

Valved Exhaust System

The SOUL Valved Exhaust System integrates directly with Porsche's factory electronically controlled exhaust valve system.

Unlike older vacuum-actuated systems that operate primarily in open or closed states, the 992.2 GTS uses electronically controlled valves that continuously vary position depending on engine operating conditions.

SOUL engineered the exhaust around this factory strategy to maintain smooth transitions as the valves change position.

Valves Open

• Enlarged 3-inch exhaust pathway

• Factory system measures approximately 2.75 inches

• Significantly increased exhaust volume

• Greater turbo presence

• Richer and more aggressive exhaust character

• Reduced restriction

• Increased flow capacity

Valves Closed

• More refined exhaust volume

• Reduced cabin presence

• Comfortable cruising characteristics

• Harmonic-dampening resonator helps suppress undesirable frequencies

• Still provides greater exhaust character than the factory system

The result is a noticeable difference between the two operating modes while retaining factory-style electronic valve control.

Performance

SOUL advertises 40+ wheel horsepower from the complete Valved Exhaust Package.

During development of its 992.2 GTS exhaust systems, SOUL has recorded gains exceeding 50 wheel horsepower and 40 lb-ft of torque with its high-flow exhaust configuration and factory engine software, with the majority of those gains attributed to the reduction in restriction provided by the upgraded downpipe.

The T-Hybrid's electrically assisted turbocharger is particularly well suited to the increased exhaust-flow capacity because the electric motor assists turbo response while the less restrictive exhaust allows the engine to move considerably more exhaust gas at higher load.

Check Engine Light / Emissions Notice

SOUL engineered the Sport Cat Downpipe to replicate factory GPF pressure differentials and oxygen-sensor behavior to help minimize the potential for a check engine light on otherwise untuned vehicles.

This should not be interpreted as a guarantee that a check engine light can never occur.

The Sport Cat Downpipe replaces the factory catalytic converter and removes the factory gasoline particulate filter. Customers are responsible for verifying emissions requirements and legality for their vehicle and jurisdiction.

Product Description

The SOUL Valved Exhaust System is designed specifically for the 992.2 Porsche 911 Carrera GTS T-Hybrid platform, providing a substantial increase in exhaust sound and flow while retaining full integration with Porsche's factory electronic exhaust-valve system.

SOUL replaces the restrictive factory rear exhaust with an enlarged 3-inch valves-open flow path, compared with approximately 2.75 inches from the factory. An integrated high-flow harmonic-dampening resonator controls undesirable frequencies without sacrificing the aggressive character expected when the valves are open.

Rather than replacing Porsche's electronic valve strategy, the SOUL system works directly with the factory exhaust-valve actuators and PSE programming. This preserves the smooth, continuously variable valve operation of the 992.2 GTS while creating a much more noticeable difference between refined valves-closed cruising and aggressive valves-open driving.

Purpose-engineered 3D-printed 316L stainless steel inlet and outlet sections optimize exhaust flow through the system, while .065-inch-wall T304L stainless tubing provides strength and durability for demanding street and track use.

The complete SOUL system weighs approximately 22.15 lbs, compared with approximately 29.1 lbs for the factory components, saving approximately 6.9 lbs / 3.1 kg.

FACTORY ELECTRONIC VALVE INTEGRATION:

The 992.2 Carrera GTS uses electronically controlled exhaust valves rather than the simpler vacuum-operated valves found on earlier Porsche models.

These valves are capable of operating at variable positions, rather than simply switching between fully open and fully closed.

Porsche adjusts valve position according to factors including engine speed, throttle input, drive mode, and vehicle operating conditions.

Even during full-throttle acceleration in Sport mode, the factory programming does not necessarily command the valves to remain 100% open at all times.

SOUL engineered the Valved Exhaust specifically around this behavior.

Rather than creating an abrupt transition between two completely different exhaust paths, the SOUL system is designed to produce a smooth change in sound as the valves progressively move.

VALVES OPEN:

With the exhaust valves open, gases flow through the system's enlarged 3-inch primary exhaust path.

Compared with the approximately 2.75-inch factory architecture, the larger path provides greater flow capacity and substantially more sound.

Expect:

• Significantly increased exhaust volume

• Greater turbocharger presence

• Stronger flat-six engine character

• Deeper and more aggressive exhaust tone

• More mechanical feedback under acceleration

• Increased sound throughout the RPM range

• Reduced exhaust restriction compared with the factory rear system

The valves-open configuration is designed for drivers who want considerably more character from the T-Hybrid powertrain without permanently sacrificing cruising refinement.

VALVES CLOSED:

When the factory valves close, the SOUL system substantially reduces overall exhaust volume.

This provides:

• Refined cold-start behavior

• Lower neighborhood departure volume

• Reduced cabin presence

• Comfortable highway cruising

• Smoother low-load exhaust character

• Significantly more refinement than a permanently open non-valved exhaust

SOUL specifically developed the system to create a meaningful sound difference between valves-open and valves-closed operation.

HIGH-FLOW HARMONIC-DAMPENING RESONATOR:

Rather than relying on a heavily restrictive muffler to control sound, SOUL incorporates an integrated high-flow harmonic-dampening resonator.

The resonator targets undesirable frequencies across the RPM range while maintaining a freer-flowing exhaust path.

This allows the system to produce considerably more volume and character when desired without introducing the persistent cabin resonance commonly associated with aggressive aftermarket exhaust systems.

SOUL reports that undesirable cabin presence is kept to an absolute minimum during cruising.

3D-PRINTED 316L INLETS & OUTLETS:

SOUL uses next-generation metal additive manufacturing for critical sections of the exhaust.

The inlet and outlet transitions are 3D printed from 316L stainless steel.

This manufacturing technique allows SOUL to create complex internal geometries optimized specifically around exhaust flow, rather than being limited to shapes that can easily be produced from conventional bent and welded tubing.

The result is a more controlled transition through the exhaust system while maintaining strength and durability.

3-INCH VS. FACTORY 2.75-INCH FLOW PATH:

The factory valves-open exhaust path measures approximately:

2.75 inches

SOUL increases the primary valves-open path to:

3.0 inches

The larger diameter increases available exhaust-flow capacity while reducing restriction through the rear exhaust.

This becomes increasingly useful as additional modifications—particularly a freer-flowing downpipe—are added to the vehicle.

SOUND CHARACTER:

The 992.2 Carrera GTS has a noticeably different exhaust character from naturally aspirated Porsche GT models.

Its integrated unequal-length turbo manifolds create a rich, deep turbocharged flat-six tone rather than the extremely high-pitched character associated with a GT3.

SOUL developed the system to enhance that natural engine character rather than attempting to artificially make the GTS sound like a naturally aspirated GT car.

Expect:

• Richer exhaust tone

• Deeper low-RPM character

• Increased turbocharged flat-six presence

• Greater volume throughout the rev range

• Significantly more aggressive valves-open operation

• Refined valves-closed cruising

• Smooth changes in volume as the factory valves operate

• Minimal undesirable cabin drone

The final sound level will also depend heavily on the downpipe installed.

WITH FACTORY DOWNPIPE:

The SOUL Valved Exhaust can be installed as a standalone rear exhaust upgrade while retaining the original Porsche downpipe.

This configuration provides:

• Increased exhaust volume

• Stronger flat-six character

• Larger 3-inch valves-open flow path

• Reduced rear-exhaust restriction

• Retention of factory electronic valve control

• Maximum emissions-system retention upstream

This is the more conservative configuration for customers who primarily want improved sound.

WITH SOUL SPORT CAT DOWNPIPE:

The Valved Exhaust is fully compatible with the SOUL Sport Cat Downpipe.

Combining the two creates a substantially more aggressive complete exhaust configuration.

Expect:

• Significantly increased turbocharger sound

• Greater boost and spool volume

• Reduced post-turbine restriction

• Stronger engine character

• Increased overall exhaust flow

• Greater exhaust volume with the valves open

• Continued valves-closed cruising refinement

This combination is also available from SOUL as its complete Valved Exhaust Package.

VALVED EXHAUST VS. PERFORMANCE EXHAUST:

SOUL Valved Exhaust System

• Rear exhaust only

• Retains factory electronic exhaust valves

• 3-inch valves-open flow path

• High-flow harmonic-dampening resonator

• Meaningful quiet and loud operating modes

• Approximately 6.9 lbs lighter than factory

• Compatible with factory or upgraded downpipe

• Best suited to mixed street and performance use

SOUL Performance Exhaust System

• Complete turbo-back system

• Includes Sport Cat Downpipe

• Full 3.5-inch exhaust architecture

• Non-valved

• No quiet mode

• Maximum exhaust flow and volume

• Manufacturer-reported gains exceeding 50 whp and 40 lb-ft on factory ECU software

The Valved Exhaust is the better choice for customers who want significantly more sound while preserving factory-style control over exhaust volume.

WEIGHT SAVINGS:

Factory Rear Exhaust Components:
Approximately 29.1 lbs / 13.2 kg

SOUL Valved Exhaust System:
Approximately 22.15 lbs / 10.0 kg

Approximate Weight Savings:
6.9 lbs / 3.1 kg

This represents approximately a 24% reduction in rear exhaust weight while also increasing the valves-open exhaust diameter and retaining full electronic valve functionality.

BOLT-ON INSTALLATION:

The Valved Exhaust System is designed as a direct replacement for the factory rear exhaust.

SOUL includes:

• High-grade installation hardware

• Required mounting components

• Resonator heat shield

The system is fixture-tested before shipment to ensure consistent fitment.

Product Description

The SOUL Performance Exhaust System is a complete turbo-back exhaust solution developed specifically for the Porsche 992.2 Carrera GTS T-Hybrid platform.

The factory GTS powertrain has tremendous exhaust-flow potential thanks to Porsche's electrically assisted turbocharger, but the original system forces exhaust through an extremely restrictive GPF and catalytic-converter assembly before entering the factory valved rear exhaust. SOUL replaces this entire architecture with a high-flow 300-cell Sport Cat Downpipe and full 3.5-inch non-valved rear exhaust system.

By eliminating the factory GPF, replacing the restrictive catalyst, removing the rear muffler and exhaust valves, and increasing exhaust diameter from approximately 2.75 inches to 3.5 inches from the turbo back, SOUL dramatically reduces exhaust restriction while producing a far more aggressive T-Hybrid soundtrack.

Despite its high-output, non-valved design, an integrated Helmholtz chamber is tuned specifically around the GTS platform's 2,200–2,800 RPM resonance range to reduce unwanted cabin drone and rasp.

SOUL reports gains of more than 50 wheel horsepower and 40 lb-ft of torque on factory ECU software, making this one of the most substantial bolt-on performance upgrades available for the 992.2 Carrera GTS.

COMPLETE TURBO-BACK DESIGN:

The SOUL Performance Exhaust replaces the 992.2 Carrera GTS exhaust system beginning immediately after the electrically assisted turbocharger and continuing through the rear of the vehicle.

The package combines:

SOUL High-Flow Sport Cat Downpipe

with

SOUL 3.5-Inch Performance Rear Exhaust

This creates one integrated turbo-back exhaust system rather than simply replacing the rear muffler.

The factory exhaust averages approximately 2.75 inches in diameter. SOUL increases the system to 3.5 inches from the turbo back, providing substantially greater available flow capacity.

T-HYBRID / eTURBO ARCHITECTURE:

The 992.2 Carrera GTS uses Porsche's T-Hybrid powertrain with a single electrically assisted turbocharger.

A conventional large turbocharger and large-diameter exhaust system can introduce significant turbo lag because the exhaust system must move a greater volume of gas before sufficient turbine speed is achieved.

Porsche's electrically assisted turbo changes that equation.

The integrated electric motor dramatically accelerates turbocharger response, allowing the engine to take advantage of large exhaust-flow cross-sections without the lag normally associated with such an architecture.

SOUL's 3.5-inch Performance Exhaust is designed to complement that high-flow potential by removing much of the restriction downstream of the eTurbo.

FACTORY GPF RESTRICTION:

SOUL describes the factory GTS downpipe as one of the most restrictive exhaust components it has encountered on a performance vehicle.

After leaving the turbocharger, exhaust gases must pass through a very large GPF assembly and restrictive catalytic converter.

Despite the T-Hybrid powertrain's high available exhaust flow, this factory emissions assembly significantly limits how efficiently exhaust gases can leave the turbine.

SOUL removes the restrictive GPF architecture and replaces the factory catalyst with a much freer-flowing 300-cell performance catalytic converter.

300-CELL SPORT CATALYST:

The Performance Exhaust retains a catalytic converter rather than using a completely catless downpipe.

SOUL uses its own:

• 300-cell performance catalyst

• Custom-specified precious-metal coating

• Triple-metal-matrix catalyst core

The catalyst is designed to provide substantially more exhaust flow than the factory assembly while maintaining a catted exhaust configuration.

3D-PRINTED 316L TURBO INLET:

The downpipe inlet is produced using next-generation metal additive manufacturing.

SOUL 3D prints the inlet from 316L stainless steel, allowing the internal shape to be optimized specifically for the transition from the electrically assisted turbocharger into the performance catalytic converter.

This manufacturing method allows SOUL to create flow geometry that would be difficult to reproduce using conventional cut, bend, and weld fabrication.

FULL 3.5-INCH EXHAUST:

After the Sport Cat Downpipe, exhaust continues through a full 3.5-inch rear exhaust system.

Compared with the approximately 2.75-inch factory architecture, the increased diameter provides substantially greater cross-sectional flow area.

This helps support:

• Increased exhaust flow

• Reduced backpressure

• Improved turbocharger efficiency

• Greater performance potential

• Stronger response throughout the powerband

• Future higher-output engine configurations

NON-VALVED PERFORMANCE DESIGN:

The factory 992.2 Carrera GTS uses electronically controlled exhaust valves that progressively open and close depending on engine operating conditions.

Even under full throttle in Sport mode, Porsche's factory valve strategy does not necessarily leave the valves fully open.

The SOUL Performance Exhaust removes both the factory exhaust valves and rear muffling.

This means the exhaust operates through its unrestricted performance path continuously.

There is no quiet mode.

The system is therefore intended for customers who prioritize sound, flow, and performance over factory-style exhaust-volume control.

HELMHOLTZ ANTI-DRONE SYSTEM:

A full 3.5-inch non-valved exhaust can easily introduce undesirable low-frequency resonance if the system is not acoustically engineered.

SOUL identified inherent drone frequencies around approximately:

2,200–2,800 RPM

and incorporated a tuned Helmholtz chamber to target that range.

The chamber reduces the specific sound frequencies responsible for undesirable cabin resonance without substantially restricting the main exhaust path.

The result is an aggressive system with active cabin presence but relatively controlled highway cruising characteristics.

SOUND CHARACTER:

The Performance Exhaust is intentionally much more aggressive than the factory system.

Expect:

• Constant turbocharger and engine sound

• Significantly greater boost noise

• Stronger turbo spool and whistle

• A deep turbocharged flat-six growl

• Increased mechanical character

• Stronger exhaust note throughout the RPM range

• Noticeably increased sound during deceleration

• No factory valve intervention

• No quiet exhaust mode

• Minimal unwanted drone for a system of this volume

SOUL notes that the unequal-length factory exhaust manifolds naturally give the 992.2 GTS a tone that is less like the traditional high-pitched naturally aspirated GT3 flat-six and more reminiscent of the muscular growl of a classic 930 Turbo.

The Performance Exhaust is tuned to enhance that natural character rather than attempt to make the T-Hybrid engine sound like a GT3.

PERFORMANCE:

The increased exhaust diameter, removal of the restrictive factory GPF, freer-flowing 300-cell catalyst, and non-valved 3.5-inch rear system dramatically reduce exhaust restriction.

SOUL reports gains of:

More than +50 wheel horsepower

More than +40 lb-ft of torque

Importantly, these results were achieved with the factory ECU software.

SOUL reports that the increased efficiency produces better response and a noticeably stronger pull throughout the power curve, with the eTurbo allowing the gains to arrive almost immediately.

These are manufacturer-reported gains for the complete SOUL Performance Exhaust System.

FACTORY GPF / O2 SENSOR INTEGRATION:

Removing the factory GPF introduces significant diagnostic challenges because Porsche monitors particulate-filter behavior and exhaust pressure.

SOUL engineered provisions into the Performance Exhaust to reproduce the factory system's expected GPF pressure differentials while also accounting for oxygen-sensor behavior.

The goal is to help minimize the possibility of a check engine light on an otherwise stock, untuned vehicle.

This should be understood as an engineered CEL-mitigation strategy rather than an unconditional guarantee that a diagnostic fault can never occur.

CHECK ENGINE LIGHT:

SOUL went to significant lengths to replicate the factory GPF pressure differentials and oxygen-sensor behavior.

This engineering is intended to help minimize the potential for a check engine light on otherwise untuned vehicles.

SOUL does not describe this as an unconditional no-CEL guarantee.

EMISSIONS NOTE:

The Performance Exhaust retains an aftermarket high-flow catalytic converter but eliminates the original Porsche GPF and replaces other factory emissions-related exhaust components.

Replacing or removing factory emissions equipment may not comply with regulations governing vehicles operated on public roads.

Customers are responsible for determining compliance with all applicable federal, state, local, and international regulations before installation or use.

Product Description

The SOUL VTA Charge Pipe is designed specifically for the 992.2 Porsche 911 Carrera GTS T-Hybrid platform, replacing the flexible factory charge-pipe section with a rigid aluminum assembly while converting the factory boost-release system to a vent-to-atmosphere configuration.

Porsche's T-Hybrid system uses an electrically assisted turbocharger capable of extremely rapid boost response. SOUL relocates the factory valves from the original intake tube onto its aluminum charge pipe, allowing pressurized charge air to vent directly to atmosphere during throttle lift.

The result is the distinctive “whoosh” sound associated with a vent-to-atmosphere system, along with quicker release of pressurized charge air during throttle transitions.

Because the 992.2 Carrera GTS uses a speed-density engine-management strategy rather than a conventional mass-airflow-sensor-based system, SOUL reports that venting the charge air does not create the drivability and fueling issues often associated with VTA systems on MAF-equipped vehicles. SOUL has long-term tested the system on its development GTS with no check engine lights or operating issues. SOUL Performance Products

VENT-TO-ATMOSPHERE DESIGN:

A conventional turbocharged engine must manage the compressed air trapped between the turbocharger and throttle body when the driver suddenly lifts off the accelerator.

Instead of recirculating that released charge air back into the intake tract, the SOUL VTA Charge Pipe allows it to vent directly to atmosphere.

This produces the characteristic:

“Whoosh”

during throttle lift.

For the 992.2 Carrera GTS, SOUL accomplishes this by relocating the factory valves from the original intake tube onto the new aluminum charge pipe.

The system therefore retains the factory electronic valve hardware while changing where the discharged charge air is directed. SOUL Performance Products

T-HYBRID / eTURBO APPLICATION:

The 992.2 Carrera GTS uses Porsche's electrically assisted exhaust-gas turbocharger.

An integrated electric motor can accelerate the turbocharger extremely quickly, allowing boost pressure to become available much faster than with a conventional turbocharger.

This unusually fast turbo response makes management of pressurized charge air during rapid throttle transitions especially relevant.

SOUL developed the VTA Charge Pipe specifically around this T-Hybrid architecture rather than adapting a conventional aftermarket blow-off-valve kit from an earlier Carrera platform. SOUL Performance Products

FACTORY VALVE RELOCATION:

Traditional standalone aftermarket blow-off valves are not practical on the 992.2 Carrera GTS because of the design and electronic integration of the factory components.

SOUL instead retains and relocates the factory valves.

The kit:

• Removes the factory valves from the original intake-tube locations

• Caps the original valve ports

• Relocates the valves to the SOUL aluminum charge pipe

• Allows the valves to discharge directly to atmosphere
