Product Description

The SOUL Bolt-On Exhaust Tips allow Porsche 992.1 GT3 and GT3 RS owners equipped with a compatible SOUL exhaust system to change the appearance of the rear exhaust without replacing the complete system.

Each tip is hand-fabricated from 4-inch-diameter, .065-inch-wall stainless steel tubing and mounts to SOUL's modular backing-plate system using heavy-duty Mikalor clamps. Tip depth is adjustable by nearly one inch, allowing the final position to be tailored to the vehicle and customer preference.

Two single-wall tip profiles are available—Slash Cut and Straight Cut—with a choice of Signature Satin, Brushed, or Satin Black finishes.

These tips are specifically intended for 992 GT3 / GT3 RS vehicles equipped with a compatible SOUL exhaust system. They do not bolt directly to the factory 992 GT3 rear muffler. SOUL Performance Products

4-INCH SINGLE-WALL DESIGN:

SOUL uses 4-inch single-wall stainless-steel outlets for its 992 GT3 exhaust systems.

The large-diameter outlet fills the GT3's central rear-exhaust opening while maintaining a motorsport-inspired appearance.

Because the tips are separate from the primary exhaust assembly, owners can change the style or finish later without purchasing another exhaust system.

SLASH CUT:

The Slash Cut design follows the angle of the tip opening to create a more aggressive and visually tapered appearance.

This is the more sculpted of the two available profiles and works particularly well for customers looking for a pronounced motorsport aesthetic.

STRAIGHT CUT:

The Straight Cut design uses a squared-off outlet profile for a simpler, more traditional race-exhaust appearance.

The exhaust performance is unchanged between Slash Cut and Straight Cut configurations; the choice is purely aesthetic.

TIP FINISHES:

Signature Satin

SOUL's signature stainless-steel finish provides a subdued metallic appearance that complements the exposed stainless construction of the exhaust.

Brushed

The brushed finish provides a more conventional raw-performance appearance with visible directional finishing.

Satin Black

The Satin Black option provides the darkest and most understated appearance and carries a higher retail price than the stainless finishes.

ADJUSTABLE TIP DEPTH:

The tip assemblies use clamp-style mounting rather than a permanently welded outlet.

This allows approximately one inch of fore/aft adjustment, giving the installer flexibility to position the tips relative to the bumper opening.

Once the desired position is achieved, the supplied heavy-duty clamps secure the tips to the mounting assembly. SOUL Performance Products

IMPORTANT OEM MUFFLER NOTE:

These tips should not be sold as a direct replacement for the factory 992.1 GT3 / GT3 RS exhaust tips.

For 992 applications, SOUL specifically states:

SOUL exhaust system required.

The factory Porsche muffler does not use the SOUL mounting architecture required for these tip assemblies.

Product Description

The SOUL Street Headers are designed for Porsche 992.1 GT3 and GT3 RS owners looking to improve exhaust flow, throttle response, power potential, and flat-six sound while retaining a catted exhaust configuration and the factory rear exhaust system.

The factory 992 GT3 header assemblies must incorporate restrictive emissions hardware very close to the engine, placing compromises on runner geometry, exhaust flow, and sound. SOUL replaces these assemblies with free-flowing headers built around large-diameter performance catalytic converters, optimized runners, and billet CNC-machined head flanges.

The upgraded architecture allows the 4.0-liter naturally aspirated flat-six to breathe more freely while retaining catalytic converters. Because the factory rear muffler and electronic exhaust valves remain in place, the Street Headers provide a meaningful increase in engine and exhaust character without requiring replacement of the complete rear exhaust.

WHY UPGRADE THE FACTORY HEADERS?

The factory 992.1 GT3 header assemblies are constrained by emissions, sound, packaging, durability, and production requirements.

Catalytic converters and particulate-filter-related hardware occupy a significant portion of the available exhaust path, limiting the freedom Porsche has to optimize runner geometry and exhaust flow strictly for performance.

SOUL's Street Headers replace those restrictive assemblies with a performance-oriented catted design intended to improve:

• Exhaust-gas flow

• Throttle response

• Naturally aspirated engine character

• Exhaust sound

• High-RPM breathing

The result is a less restrictive path from the cylinder heads into the factory rear exhaust while retaining catalytic converters.

BILLET CNC HEAD FLANGES:

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

The flange design serves two important purposes.

First, it creates a more efficient transition from the cylinder-head exhaust ports into the header runners.

Second, the billet construction provides additional strength in an area subjected to repeated thermal cycling and mechanical stress during aggressive street and track use.

This helps reduce the likelihood of cracking associated with repeated high-temperature operation.

HIGH-FLOW CATALYTIC CONVERTERS:

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

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

This makes the Street Headers the more road-oriented option for owners who want improved exhaust flow and sound without moving to SOUL's completely catless Competition Headers.

FACTORY REAR EXHAUST COMPATIBILITY:

The SOUL Street Headers are specifically engineered to work with the factory 992.1 GT3 / GT3 RS rear exhaust system.

The original:

• Rear muffler

• Electronic exhaust valves

• Factory valve-control strategy

• Rear exhaust outlets

remain in place.

This makes the Street Headers particularly attractive for owners who want to improve flow and sound upstream while retaining the Porsche rear exhaust hardware and valve functionality.

SOUND CHARACTER:

Replacing the restrictive factory header assemblies allows more of the GT3's naturally aspirated character to reach the rear exhaust.

Expect:

• Greater flat-six presence

• Increased mechanical engine sound

• Stronger exhaust tone under load

• More pronounced high-RPM character

• Increased sound when the factory exhaust valves open

• Greater differentiation between subdued and aggressive factory valve operation

The final sound character depends heavily on the rear exhaust installed.

With the factory rear muffler retained, the car remains more restrained than one using a SOUL Performance, Valved, Race, or High Pitch rear exhaust.

STREET HEADERS VS. COMPETITION HEADERS:

Street Headers

• Retain performance catalytic converters

• More street-oriented configuration

• Improved exhaust flow

• Increased flat-six sound

• Retain factory rear exhaust and valves

• Best suited to customers wanting increased performance while maintaining a catted configuration

Competition Headers

• Completely catless

• Remove factory catalytic-converter restrictions

• Maximum available header flow

• Greater sound increase

• More competition-focused

• Retain factory rear exhaust and valves

Both products are standalone header replacements designed around the stock rear exhaust architecture.

STREET HEADERS VS. COMPLETE EXHAUST PACKAGES:

The SOUL Street Headers should not be confused with the headers supplied as part of SOUL's complete Valved or Race Exhaust Packages.

Street Headers

• Standalone header replacement

• Retain factory rear muffler

• Retain factory exhaust valves

• Retain catalytic converters

• Single fixed configuration

Complete Exhaust Packages

• Replace both headers and rear exhaust

• Use their own downstream exhaust architecture

• Provide substantially greater changes in sound and overall exhaust configuration

• May offer catted and catless configurations

For customers retaining the factory rear exhaust, the standalone Street Headers are the appropriate product.

CHECK ENGINE LIGHT / ECU CALIBRATION:

SOUL's current 992.1 GT3 Street Header listing does not publish a blanket guarantee regarding check engine light behavior or state that an ECU calibration is required.

Because these headers replace factory emissions components with aftermarket high-flow catalytic converters, diagnostic behavior can depend on vehicle specification, software, sensor condition, and market.

No tune or check-engine-light guarantee should be assumed beyond SOUL's current published product information.

EMISSIONS NOTE:

The SOUL Street Headers retain catalytic converters but replace the original Porsche emissions components with aftermarket performance parts.

They are not CARB certified.

Retaining catalytic converters does not necessarily make the headers legal for road use in every jurisdiction.

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

Porsche 992.1 GT3 / GT3 RS SOUL Competition Headers

$4,795.00

Product Description

The SOUL Competition Headers are designed for Porsche 992.1 GT3 and GT3 RS owners looking to remove one of the most restrictive portions of the factory exhaust while retaining the factory rear exhaust system.

The factory header assemblies incorporate the catalytic converters and particulate-filter sections, forcing compromises in primary-runner length, diameter, collector design, sound, and exhaust flow. SOUL replaces these assemblies with long-tube stainless steel headers featuring optimized runners and billet CNC-machined merge collectors engineered around the 4.0-liter naturally aspirated flat-six.

The resulting design improves exhaust flow, throttle response, and engine character while allowing significantly more of the GT3's naturally aspirated sound to reach the factory rear exhaust.

These are SOUL's most performance-focused standalone headers for owners who want to retain the factory rear muffler while eliminating the restrictive factory header and emissions assemblies. SOUL Performance Products

LONG-TUBE HEADER DESIGN:

Even on a GT3, the factory exhaust manifold must satisfy emissions, packaging, noise, manufacturing, and regulatory requirements.

The factory header assemblies incorporate catalytic converters and particulate-filter hardware very close to the engine. This places significant restrictions on runner length, collector design, and available exhaust flow.

SOUL's Competition Headers remove those constraints and replace the factory assemblies with dedicated long-tube runners optimized around performance rather than emissions packaging.

The goal is to improve the way exhaust pulses travel from each cylinder into the collector while reducing restriction before the factory rear exhaust.

CNC-MACHINED MERGE COLLECTORS:

The merge collector is a critical component of a naturally aspirated performance header.

SOUL uses billet CNC-machined merge collectors rather than relying on a basic stamped or fabricated convergence of the individual runners.

The optimized collector architecture is designed to merge exhaust pulses more efficiently while maintaining exhaust-gas velocity.

On the GT3's high-revving naturally aspirated engine, improved collector geometry can contribute to:

• Better exhaust scavenging

• Improved throttle response

• Stronger midrange character

• Improved high-RPM breathing

• A cleaner transition between the individual primary runners and downstream exhaust

The complete header is designed as a system rather than simply increasing tubing diameter.

FACTORY REAR EXHAUST COMPATIBILITY:

These Competition Headers are specifically designed to work with the factory 992.1 GT3 / GT3 RS rear exhaust.

The factory rear muffler, electronic exhaust valves, exhaust tips, and associated rear-exhaust functionality remain in place.

This makes the Competition Headers particularly attractive for owners who want:

• Reduced exhaust restriction

• Increased engine sound

• Improved response

• Factory rear muffler packaging

• Continued factory exhaust-valve operation

The final exhaust volume will still be influenced by the factory rear muffler and Porsche's electronic valve-control strategy.

SOUND CHARACTER:

Removing the restrictive factory header, catalyst, and particulate-filter assemblies allows substantially more of the GT3's natural exhaust character to reach the rear muffler.

Expect:

• Greater mechanical engine sound

• Stronger naturally aspirated flat-six character

• Increased exhaust presence throughout the rev range

• More aggressive tone under load

• Greater high-RPM intensity

• More noticeable changes when the factory rear exhaust valves open

• Significant amplification of whichever rear exhaust system is installed downstream

With the stock rear muffler retained, the resulting sound remains more controlled than SOUL's complete Race Exhaust or High Pitch Exhaust systems.

THROTTLE RESPONSE & PERFORMANCE:

SOUL developed the Competition Headers around improvements in exhaust flow and throttle response.

The factory emissions assemblies create substantial restriction immediately downstream of the engine. Removing those restrictions allows exhaust gases to leave the cylinders more efficiently and gives the 4.0-liter flat-six a less restrictive downstream path.

SOUL does not currently publish a standalone horsepower or torque figure for these headers, so no specific power gain should be assumed.

COMPETITION HEADERS VS. STREET HEADERS:

The Competition Headers eliminate the factory catalytic converters and particulate-filter assemblies entirely for maximum available exhaust flow and sound.

The Street Headers are the more street-oriented alternative and incorporate high-flow catalytic converters.

Competition Headers

• Catless

• No particulate-filter sections

• Maximum available exhaust flow

• Maximum header-induced sound increase

• Lower restriction

• Competition-oriented configuration

Street Headers

• Retain high-flow catalytic converters

• More street-oriented configuration

• Reduced emissions-hardware removal compared with Competition Headers

• Higher purchase price

For customers prioritizing outright flow and sound, the Competition Headers are the more aggressive option.

COMPETITION HEADERS VS. COMPLETE RACE EXHAUST:

These standalone Competition Headers should not be confused with the header architecture supplied as part of SOUL's complete Race Exhaust System.

Competition Headers

• Standalone header replacement

• Designed to connect to the factory rear exhaust

• Retains factory rear muffler

• Retains factory electronic exhaust valves

• One fixed configuration

Race Exhaust System

• Complete header-back exhaust

• Replaces the factory rear exhaust

• Uses SOUL-specific downstream connections and exhaust architecture

• Available with catted or catless sections

• Non-valved rear exhaust

• Multiple exhaust-tip configurations

For customers keeping the factory rear exhaust, these Competition Headers are the appropriate standalone product.

CHECK ENGINE LIGHT:

Because the Competition Headers remove the factory catalytic converters and particulate-filter assemblies, emissions-related diagnostic trouble codes and a check engine light are possible.

An appropriate ECU calibration or diagnostic solution may be required depending on vehicle specification and intended competition use.

Customers should not expect factory catalyst-monitoring functionality to operate normally after installation of a catless header system.

EMISSIONS / COMPETITION USE NOTE:

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

This product is not CARB certified and may not be legal for use on emissions-controlled vehicles on public roads.

The headers are intended for closed-course competition use only where required.

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

Product Description

F1-INSPIRED HIGH-PITCH DESIGN:

The High Pitch Exhaust is fundamentally different from a conventional muffler-delete or X-pipe exhaust.

SOUL developed the complete exhaust path around acoustic tuning rather than simply removing restriction.

After leaving the headers, exhaust flows through reverse megaphones before entering two 2.5-inch exhaust paths. The two banks then merge into a single 3-inch section of carefully calculated length.

The transition from dual exhaust paths into one centralized flow path changes the way the individual cylinder-bank pulses interact, pushing the exhaust note toward a higher and more continuous frequency.

The goal is a progressively sharper motorsport sound that becomes increasingly exotic as engine speed approaches the GT3's redline. SOUL Performance Products

REVERSE MEGAPHONES:

Rather than connecting the header outlets directly into conventional constant-diameter tubing, SOUL incorporates reverse megaphones into the exhaust architecture.

These transitions are part of the system's acoustic and flow tuning and help transition exhaust gases from the header outlets into the downstream dual 2.5-inch system.

Combined with the later single 3-inch merge, the complete geometry is designed around maintaining exhaust velocity while manipulating exhaust frequency.

DUAL 2.5-INCH TO SINGLE 3-INCH EXHAUST:

The two cylinder banks initially remain separated through 2.5-inch exhaust tubing.

Farther downstream, the banks merge into a single 3-inch exhaust path.

SOUL carefully calculated the length and placement of this merged section to influence exhaust tone while maintaining efficient exhaust flow.

This is a very different architecture from the conventional dual-bank X-pipe used on SOUL's Performance and Race Exhaust systems.

SOUND CHARACTER:

The SOUL High Pitch Exhaust is designed specifically for customers prioritizing an extreme motorsport soundtrack.

Expect:

• Dramatically increased overall exhaust volume

• Sharper exhaust frequency

• Higher-pitched flat-six character

• Significantly greater mechanical engine sound

• An increasingly exotic tone as RPM rises

• Aggressive naturally aspirated sound throughout the rev range

• A focused motorsport character rather than a conventional deep aftermarket exhaust note

• Maximum sound without factory exhaust-valve intervention

This is a competition-focused system, not a quiet or dual-purpose valved exhaust.

3D-METAL-PRINTED CENTER OUTLET:

One of the defining features of the High Pitch Exhaust is its single center exhaust outlet.

Rather than using conventional fabricated twin tips, SOUL digitally engineered the outlet and manufactures it using its own 3D metal printers.

The tip is constructed from 316L stainless steel and shaped to integrate within the GT3's factory bumper surround.

The printed construction gives SOUL greater freedom over the internal and external geometry than would be possible with conventional bent and welded tubing.

The resulting outlet provides a distinctive motorsport appearance while also being designed to limit unnecessary heat transfer into the surrounding bumper area. SOUL Performance Products

VALVE DELETE MODULES:

The factory 992 GT3 uses electronically monitored exhaust valves.

The High Pitch Exhaust eliminates the factory valved rear exhaust entirely.

SOUL therefore includes dedicated Valve Delete Modules that replicate the electrical signals expected from the original valve actuators.

This allows the factory valves and actuators to be removed while making the ECU recognize the system as operating normally, preventing a valve-related check engine light.

WEIGHT SAVINGS:

The factory exhaust components weigh approximately:

68.2 lbs / 30.9 kg

The complete SOUL High Pitch Exhaust weighs approximately:

35.9 lbs / 16.3 kg

Approximate weight reduction:

32.3 lbs / 14.6 kg

That represents a reduction of approximately 47% of the factory exhaust-system weight.

Because much of the factory exhaust mass is positioned at the rear of the vehicle, this is a particularly meaningful reduction for a performance-focused GT3 or GT3 RS.

HIGH PITCH VS. PERFORMANCE EXHAUST:

High Pitch Exhaust System

• Complete header-back system

• Removes factory catalyst assemblies

• Eliminates particulate-filter sections

• Removes factory exhaust valves

CATALYTIC CONVERTERS / EMISSIONS EQUIPMENT:

The High Pitch Exhaust removes the factory catalytic-converter assemblies and particulate-filter sections as part of the complete system.

There is no catted version listed for this product.

Removing the factory emissions equipment may produce emissions-related diagnostic trouble codes depending on vehicle specification and ECU configuration.

European-specification vehicles require an appropriate OBD solution or ECU calibration according to SOUL.

EUROPEAN-SPEC VEHICLES:

SOUL states that the High Pitch Exhaust physically fits applicable European-specification GT3 and GT3 RS models.

Because European vehicles use different emissions monitoring and particulate-filter strategies, SOUL requires an appropriate OBD device or ECU calibration to eliminate resulting check engine lights.

EMISSIONS / COMPETITION USE NOTE:

The SOUL High Pitch Exhaust System removes factory catalytic converters and particulate-filter hardware.

This product is not CARB certified and may not be legal for use on emissions-controlled vehicles.

SOUL specifies the system as intended for closed-course competition use only where required.

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

Product Description

The SOUL Performance Exhaust System is designed for Porsche 992.1 GT3 and GT3 RS owners who want substantially more sound throughout the entire rev range without replacing the factory headers or catalytic-converter assemblies.

The factory GT3 exhaust uses electronically controlled valves and programming that keeps much of the 4.0-liter flat-six's character subdued until higher engine speeds. SOUL eliminates the secondary valved flow path entirely, replacing the factory rear muffler with a non-valved 3-inch X-pipe exhaust system.

Exhaust flows from the factory headers through SOUL's purpose-built smooth-radius cast transition cones, into 3-inch tubing, through a bespoke X-pipe, and out through the customer's choice of 4-inch exhaust tips.

Tailored Helmholtz resonators target the resonance encountered during development around 3,400–4,000 RPM, helping maintain reasonable cabin presence while preserving the aggressive, higher-pitched flat-six character of the GT3.

NON-VALVED PERFORMANCE DESIGN:

The factory 992 GT3 uses electronically controlled exhaust valves to manage sound throughout the rev range.

Even when Porsche Sport Exhaust is selected, the factory programming can restrict the car's exhaust character until approximately 5,000 RPM.

The SOUL Performance Exhaust removes this valved secondary-flow architecture entirely.

Instead, the system provides one dedicated exhaust path through the cast transition cones, 3-inch piping, X-pipe, and 4-inch exhaust tips.

The result is immediate access to substantially more of the GT3's natural exhaust sound regardless of factory valve programming.

CAST TRANSITION CONES:

The factory exhaust exits through large header flanges before entering the rear muffler assembly.

SOUL developed unique cast transition cones to smoothly reduce this large factory connection into the 3-inch rear exhaust.

Rather than using a short, aggressive fabricated taper, SOUL designed the transition in CAD with a gradual internal radius intended to preserve exhaust flow.

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

The cast construction also reduces the number of welded joints compared with a multi-piece fabricated transition, improving durability and consistency.

3-INCH X-PIPE:

Once through the cast transitions, exhaust travels through 3-inch tubing into SOUL's dedicated X-pipe.

The crossover blends exhaust pulses from the opposing cylinder banks, helping create a smoother and more continuous exhaust tone.

For the GT3's high-revving naturally aspirated 4.0-liter flat-six, the result is a more pronounced, higher-pitched character as RPM increases.

HELMHOLTZ RESONATORS:

During development, SOUL identified a resonance / drone range around approximately 3,400–4,000 RPM.

Rather than adding conventional mufflers to the primary exhaust path, SOUL uses specifically tuned Helmholtz resonators to target these undesirable frequencies.

This allows the Performance Exhaust to remain:

• Free flowing

• Non-valved

• Aggressive throughout the rev range

• More comfortable inside the cabin than an unresonated muffler-delete system

The resonators are intended to reduce and smooth resonance, not make the system silent.

SOUND CHARACTER:

The SOUL Performance Exhaust provides a major increase in sound while remaining less extreme than a complete header-back Race Exhaust.

Expect:

• Throatier low-RPM sound

• Greater flat-six presence during normal driving

• Increased mechanical engine character

• More immediate exhaust feedback from throttle inputs

• Stronger sound throughout the rev range

• A smoother tone through the X-pipe

• Progressively more aggressive character as RPM rises

• A pronounced high-RPM flat-six wail

• No dependence on factory exhaust-valve programming

SOUL describes the resulting volume as similar to the center muffler bypass systems used on previous 997- and 991-generation GT3 models.

FACTORY HEADERS & CATALYTIC CONVERTERS:

This Performance Exhaust System is a rear exhaust upgrade only.

It retains the Porsche factory:

• Headers

• Catalytic converters

• Emissions equipment

Because the factory header and catalyst assemblies remain installed, SOUL states that installing this rear exhaust does not affect the vehicle's emissions requirements.

Customers looking for replacement headers or a complete header-back solution should instead consider SOUL's Race Exhaust System or Valved Exhaust Package.

VALVE DELETE MODULES:

Removing the factory rear exhaust also removes the original electronic exhaust valves.

The vehicle electronics expect those valve actuators to remain present and functioning.

SOUL includes dedicated Valve Delete Modules that replicate the expected factory valve signals, allowing the original valved exhaust hardware to be removed without creating a valve-related check engine light.

No separate exhaust-valve controller is required for the Performance Exhaust itself because the new exhaust contains no valves.

PERFORMANCE EXHAUST VS. VALVED EXHAUST:

Performance Exhaust System

• Non-valved

• 3-inch X-pipe architecture

• Exhaust sound available throughout the RPM range

• Helmholtz resonators control undesirable resonance

• Simpler, lighter rear exhaust architecture

• Best suited to owners who prioritize sound and do not need a quiet mode

Valved Exhaust System

• Retains electronic exhaust valves

• Quieter muffled flow path available

• More refined cruising character

• Factory-style changes in exhaust volume

• Better suited to owners prioritizing maximum street refinement

PERFORMANCE EXHAUST VS. RACE EXHAUST:

Performance Exhaust

• Rear exhaust only

• Retains factory headers

• Retains factory catalytic converters

• Non-valved

• Lower purchase price

• Significant sound increase without replacing emissions components

Race Exhaust

• Complete header-back system

• Replaces factory headers

Porsche 992.1 GT3 / GT3 RS SOUL Valved Exhaust System

from $5,755.00

Product Description

The SOUL Valved Exhaust System is designed for Porsche 992.1 GT3 and GT3 RS owners looking for a substantial improvement in sound while retaining the factory headers, catalytic-converter assemblies, and electronically controlled exhaust valves.

Rather than replacing the complete exhaust system, this system replaces the factory rear muffler assembly and connects to the existing header outlets through SOUL's purpose-built smooth-radius cast transition cones.

With the valves open, exhaust flows through 3-inch piping into a large-diameter X-pipe, blending the two cylinder banks for a smoother, higher-pitched flat-six exhaust note. With the valves closed, exhaust is progressively directed through SOUL's bespoke X-chamber muffler, which uses straight-through perforated tubing, acoustic packing, and an internal X-pipe to reduce unwanted resonance while maintaining a more engaging tone than the factory exhaust.

The result is an OEM+ style system that preserves factory-controlled valve operation and cruising refinement while providing significantly greater mechanical character and an aggressive high-RPM wail when the valves open. SOUL Performance Products

CAST TRANSITION CONES:

The factory GT3 exhaust uses a large outlet from the factory header and emissions assembly before entering the rear muffler.

SOUL developed dedicated cast transition cones to create a gradual transition into the aftermarket rear exhaust.

Rather than using an aggressively tapered fabricated section, the cast design allows SOUL to optimize the radius and internal shape from CAD through final machining.

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

The design reduces unnecessary weld joints while creating a smooth exhaust path into the rear system. SOUL Performance Products

VALVES OPEN:

As the factory electronic valves open, exhaust flows through the system's primary 3-inch piping and external X-pipe.

This configuration provides:

• Increased overall exhaust volume

• Higher-pitched flat-six character

• Stronger mechanical engine tone

• Greater high-RPM presence

• Smoother blending between the two cylinder banks

• More aggressive character at wide-open throttle

Unlike a simple bypass-style system, some sound energy continues to interact with the secondary muffled path even when the valves are open. SOUL uses this intentionally to smooth the exhaust tone and reduce unwanted resonance without adding additional resonators to the primary path. SOUL Performance Products

VALVES CLOSED:

With the valves closed, exhaust is routed through SOUL's bespoke X-chamber muffler.

The muffler uses straight-through perforated piping surrounded by acoustic packing rather than a highly restrictive chambered flow path.

An internal X-pipe allows exhaust from both cylinder banks to merge inside the muffler.

This provides:

• Reduced cruising volume

• Smoother low-RPM tone

• Reduced cabin drone

• Increased refinement during normal driving

• More exhaust character than the factory rear muffler

• A more gradual transition between quiet and aggressive operation

SOUL specifically developed this architecture to control resonance in the sub-3,000 RPM range. SOUL Performance Products

FACTORY ELECTRONIC VALVE OPERATION:

The 992 GT3 uses electronically actuated exhaust valves rather than simple vacuum-operated valves.

SOUL states that the factory programming generally operates the valves as follows:

• Closed below approximately 4,000 RPM

• Gradually opening between approximately 4,000 and 5,000 RPM

• Fully open at approximately 5,000 RPM

Even with PSE activated, the factory control strategy can close the valves again under acceleration before progressively reopening them as RPM increases.

The SOUL Valved Exhaust retains this factory-controlled behavior.

For owners looking for complete valve override and 100% open operation regardless of RPM, SOUL notes that ECU calibration or an appropriate aftermarket valve controller can alter the factory strategy. SOUL Performance Products

SOUND CHARACTER:

SOUL designed this system as a refined OEM+ valved exhaust rather than its most extreme GT3 offering.

Expect:

• Greater exhaust presence during casual driving

• Smoother flat-six tone

• Higher-pitched character throughout the RPM range

• Increased mechanical engine sound

• More refined tone than the hollow factory rear exhaust

• Comfortable cabin presence during normal driving

• Moderate increase in aggression at wide-open throttle

• Stronger high-RPM wail as the valves progressively open

SOUL describes the system as a "gentleman's OEM+" type of experience: clearly more exciting than stock, but substantially more restrained than its Race Exhaust System. SOUL Performance Products

FACTORY HEADERS & CATALYTIC CONVERTERS:

Unlike the SOUL Valved Exhaust Package, this standalone Valved Exhaust System does not include replacement headers or catalyst sections.

The factory header and emissions assemblies remain installed.

This makes the Valved Exhaust a good option for owners who primarily want to improve exhaust tone and volume without replacing the complete header and catalyst system.

Owners looking for a complete header-to-tip solution should instead consider SOUL's Valved Exhaust Package.

VALVED EXHAUST SYSTEM VS. VALVED EXHAUST PACKAGE:

Valved Exhaust System

• Rear exhaust upgrade

• Retains factory headers

• Retains factory catalyst assemblies

• Retains factory electronic valve control

• Lower cost

• Best suited to owners primarily seeking improved sound

Valved Exhaust Package

• Complete header and rear exhaust solution

• Replaces factory headers

• Available with catted or catless sections

• Greater exhaust-flow potential

• More extensive performance-oriented upgrade

• Considerably higher purchase price

EXHAUST TIP OPTIONS:

Two 4-inch single-wall exhaust-tip designs are available:

4" Slash Cut Single Wall

or

4" Straight Cut Single Wall

Each design is available in:

• Signature Satin

• Brushed

• Satin Black

Product Description

The SOUL Valved Exhaust Package is a complete header-and-rear-exhaust solution for the Porsche 992.1 GT3 and GT3 RS, combining long-tube performance headers with a purpose-built valved rear exhaust system for substantially improved flow, sound, and driver control.

SOUL replaces the restrictive factory header architecture with long-tube runners and CNC-machined merge collectors, then routes exhaust into interchangeable catted or catless sections before reaching the rear valved exhaust. With the valves open, exhaust flows through a full 3-inch X-pipe path for maximum flow and a higher-pitched, aggressive flat-six wail. With the valves closed, gases are routed through a secondary path and bespoke SOUL muffler to reduce cabin presence and drone while retaining considerably more character than the factory system.

The result is a complete exhaust package that combines the response and flow benefits of performance headers with meaningful factory-style valve control—comfortable enough for normal driving while delivering a dramatically more aggressive sound when the engine is pushed. SOUL Performance Products

LONG-TUBE HEADER DESIGN:

The SOUL Valved Exhaust Package replaces the factory headers rather than connecting only to the stock manifolds.

The factory system must accommodate emissions hardware, mass-production requirements, sound regulations, packaging constraints, and the large connection into the original rear muffler.

SOUL's long-tube design allows the primary runners and collectors to be optimized around exhaust flow and performance instead.

The headers feed directly into the interchangeable catted or catless sections before reaching the valved rear exhaust, creating a cohesive header-back system rather than combining an aftermarket rear muffler with restrictive factory manifolds.

CNC MERGE COLLECTORS:

The headers use dedicated CNC-machined merge collectors to smoothly combine the individual primary runners.

Collector geometry is particularly important on the GT3's naturally aspirated 4.0-liter engine because exhaust-pulse management can influence scavenging, engine response, midrange performance, and high-RPM breathing.

SOUL designed the collector architecture as part of the complete system rather than simply increasing tubing diameter.

VALVES OPEN:

When the factory-controlled valves open, exhaust is allowed to flow through the system's 3-inch primary piping and X-pipe.

This configuration provides:

• Maximum available exhaust flow

• Significantly greater overall exhaust volume

• Higher-pitched flat-six character

• Stronger mechanical engine tone

• Aggressive high-RPM wail

• Smooth blending of the two cylinder banks through the X-pipe

The system is designed to become increasingly aggressive as the factory valve strategy opens the exhaust at higher RPM.

VALVES CLOSED:

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

The muffler uses straight-through perforated tubing rather than forcing exhaust through a highly restrictive chambered design.

Sound energy passes through the perforations into the surrounding packing material, while an internal X-pipe blends flow from both cylinder banks.

This configuration is designed to provide:

• Reduced cabin presence

• Lower cruising volume

• Smoother low-RPM sound

• Reduced drone below approximately 3,000 RPM

• More refined sound than a muffler-less Race Exhaust

• Meaningful sound separation between casual and aggressive driving

FACTORY ELECTRONIC VALVE CONTROL:

The 992 GT3 uses electronically actuated exhaust valves.

SOUL states that the factory programming generally keeps the valves closed below approximately 4,000 RPM, gradually opens them between approximately 4,000 and 5,000 RPM, and reaches fully open operation around 5,000 RPM.

The SOUL system retains this electronically controlled behavior.

The included hardware is important because simply relocating, disconnecting, or improperly mounting the factory valve actuators can create check engine lights and performance-related problems.

For owners who want the valves commanded 100% open regardless of RPM or throttle strategy, an appropriate ECU calibration can be used to alter the factory valve logic.

SOUND CHARACTER:

The Valved Exhaust Package is designed to bridge the gap between a touring-friendly exhaust and SOUL's significantly more aggressive Race Exhaust.

Expect:

• More exhaust presence during normal driving

• Higher-pitched flat-six tone

• Greater mechanical engine character

• Smoother exhaust quality at lower RPM

• Reasonable cabin presence below approximately 4,000 RPM

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

• Aggressive high-RPM wail as the valves open

• Greater refinement than a muffler-less race system

With the valves closed, the system remains noticeably more pronounced than stock but is designed to stay controlled.

As RPM rises and the valves open, the system transitions into a much more aggressive motorsport-oriented sound.

COMPETITION / CATLESS CONFIGURATION:

The Competition configuration eliminates the catalytic converters entirely.

This provides:

• Maximum exhaust flow

• Maximum sound

• Greatest track-focused character

• Reduced exhaust restriction

• Most aggressive high-RPM exhaust note

• Ability to convert later to the catted configuration using the modular catalyst sections

Removing the catalytic converters can trigger catalyst-efficiency-related diagnostic trouble codes and a check engine light.

SOUL recommends an appropriate custom ECU calibration when necessary for track-use applications.

CATTED CONFIGURATION:

The catted configuration incorporates SOUL's current-production high-flow performance catalytic converters into the exhaust system.

This configuration:

• Retains catalytic converters

• Reduces overall exhaust volume compared with the catless version

• Maintains the full valved-exhaust architecture

• Retains the long-tube headers and high-flow X-pipe design

• Allows later conversion to the Competition configuration

SOUL's current construction specification lists a SOUL-designed 300-cell catalytic converter with a custom-specified precious-metal coating and triple-metal-matrix core. SOUL Performance Products

MODULAR CATTED / CATLESS SECTIONS:

The catalyst sections are interchangeable.

This means an owner can purchase the system in one configuration and later change between:

Competition / Catless

and

High-Flow Catted

without replacing the headers, rear valved exhaust, or exhaust tips.

This is particularly useful for GT3 owners who want a quieter catted configuration for normal use but may want the additional flow and sound of a catless configuration for closed-course events.

EXHAUST TIP OPTIONS:

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

• Slash Cut Single Wall

• Straight Cut Single Wall

Each style is offered in:

• Signature Satin

• Brushed

• Satin Black

The exhaust uses a modular tip plate similar in concept to SOUL's previous-generation GT3 systems, allowing the tip assemblies to be changed independently of the exhaust itself.

VALVED PACKAGE VS. RACE EXHAUST:

The SOUL Valved Exhaust Package and Race Exhaust share the same general philosophy of replacing the restrictive factory headers and exhaust architecture, but they target different priorities.

Valved Exhaust Package

• Retains functional electronic exhaust valves

• Bespoke muffler for quieter operation

• Reduced cruising drone

• Strong difference between casual and high-RPM driving

• Better suited to mixed street and track use

Race Exhaust

• Non-valved

• No primary muffler

• Lower weight

• Maximum exhaust volume

• More consistently aggressive character

• Better suited to owners prioritizing track use, maximum sound, and minimum weight

EUROPEAN-SPEC VEHICLES:

SOUL lists European-specification GT3 and GT3 RS models as physically compatible.

Because these vehicles use different emissions hardware and diagnostic strategies, SOUL states that European applications must be paired with an appropriate OBD device or ECU calibration to address resulting check engine lights.

CHECK ENGINE LIGHT:

The Competition / Catless configuration may trigger a check engine light because the factory catalytic converters are removed.

SOUL recommends an appropriate custom ECU calibration where necessary for closed-course use.

The catted configuration reduces the likelihood of catalyst-related diagnostic issues but replaces the factory emissions hardware and should not be treated as guaranteeing OEM-equivalent emissions-monitoring behavior.

EMISSIONS / COMPETITION USE NOTE:

The SOUL Valved Exhaust Package replaces factory emissions components and is not CARB certified.

The Competition configuration completely removes the catalytic converters.

The catted configuration replaces the factory catalysts with aftermarket high-flow units.

SOUL identifies this product for closed-course competition use only where required.

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

Product Description

The SOUL Race Exhaust System is the most performance-focused complete exhaust configuration for the Porsche 992.1 GT3 and GT3 RS, replacing the restrictive factory headers, catalytic-converter assemblies, particulate-filter sections, factory rear muffler, and exhaust valves with a lightweight, high-flow system engineered around maximum power and sound.

Long-tube headers use optimized primary runners and CNC-machined merge collectors to improve exhaust flow before feeding interchangeable catted or catless sections. From there, exhaust travels through a full 3-inch rear exhaust system and X-pipe designed to blend the two cylinder banks for a smoother, higher-pitched motorsport exhaust note.

The modular architecture allows owners to switch between the Competition catless configuration and SOUL's 300-cell high-flow catalytic-converter configuration without replacing the complete exhaust system.

The result is a dramatic reduction in exhaust-system weight, significantly increased exhaust flow, measurable naturally aspirated power gains, and a high-pitched sound designed to evoke a Porsche Cup Car or RSR-style experience. SOUL Performance Products

LONG-TUBE HEADERS:

The factory 992 GT3 exhaust manifolds must balance emissions requirements, production packaging, catalyst placement, cost, and noise regulations.

SOUL's Race Exhaust removes those compromises by replacing the original header and catalyst assemblies with a performance-focused long-tube design.

SOUL optimized the transition from the cylinder-head flange into the primary runners and uses smooth-radius bends leading into dedicated merge collectors.

Rather than using a conventional slip-fit collector, SOUL developed a bespoke billet collector designed from CAD and manufactured by CNC machining.

The design allows longer primary runners while eliminating several welded joints from the collector assembly, increasing both exhaust-flow potential and durability.

CNC-MACHINED MERGE COLLECTORS:

The merge collector is one of the most technically significant components of the Race Exhaust System.

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

The collector incorporates performance-oriented merge geometry and merge spikes to smoothly combine exhaust pulses from the individual cylinders.

The goal is to improve:

• Exhaust-gas velocity

• Cylinder-to-cylinder flow consistency

• Throttle response

• Midrange output

• High-RPM breathing

• Overall naturally aspirated engine efficiency

This architecture is particularly relevant to the GT3's 4.0-liter naturally aspirated engine, where exhaust tuning and collector design directly influence scavenging and high-RPM performance. SOUL Performance Products

FULL 3-INCH REAR EXHAUST:

After the interchangeable catalyst section, exhaust flows through a full 3-inch rear exhaust system.

The factory architecture uses large catalyst assemblies feeding an exceptionally heavy dual-entry rear muffler through a large factory connection point.

SOUL removes this architecture entirely and concentrates on maintaining exhaust flow from the headers through the rear of the vehicle.

The system is constructed from .065-inch-wall T304L stainless steel to provide the durability required for repeated high-temperature track use.

X-PIPE DESIGN:

After the catalyst or bypass sections, exhaust from both cylinder banks enters a dedicated X-pipe.

SOUL designed the crossover to minimize internal diameter reduction while maximizing communication between the two exhaust banks.

Blending the exhaust pulses produces a smoother, more continuous exhaust note and helps move the character away from two independent banks toward a higher-pitched motorsport-style wail.

The resulting sound is substantially more aggressive than the factory exhaust.

SOUND CHARACTER:

The SOUL Race Exhaust System sits at the extreme end of the 992 GT3 exhaust spectrum.

Expect:

• Dramatically increased exhaust volume

• Higher-pitched flat-six character

• Much stronger mechanical engine sound

• Aggressive high-RPM wail

• Increased exhaust presence throughout the rev range

• More immediate response to throttle inputs

• A smoother tone from the X-pipe crossover

• A Cup Car / RSR-inspired character at high RPM

SOUL specifically describes the Race Exhaust as being extreme for a street-driven vehicle.

The Competition catless configuration provides the greatest volume and most aggressive sound.

The 300-cell catted configuration reduces sound somewhat while retaining the fundamental character and high-flow design of the Race Exhaust. SOUL Performance Products

DYNO-PROVEN POWER:

SOUL had the Race Exhaust System tested by Hydra Motor Works on a Dynojet.

With the SOUL Race Exhaust System alone, testing produced peak gains of approximately:

+23 wheel horsepower

+19 lb-ft of torque

SOUL also reports strong gains through the midrange and near maximum engine speed.

When the Race Exhaust was subsequently paired with a Hydra Motor Works Stage 2 ECU calibration, SOUL reports peak gains of approximately:

+60 wheel horsepower

+26 lb-ft of torque

with maximum gains at portions of the power curve exceeding:

+60 wheel horsepower

+70 lb-ft of torque

The +23 whp / +19 lb-ft figures are the exhaust-only test results. The larger numbers represent the combined exhaust and ECU calibration rather than the exhaust alone. SOUL Performance Products

WEIGHT SAVINGS:

The factory exhaust components weigh approximately:

68.2 lbs / 30.9 kg

The complete Competition / Catless Race Exhaust weighs approximately:

42.9 lbs / 19.5 kg

Approximate weight savings:

25.3 lbs / 11.4 kg

The complete Catted Race Exhaust weighs approximately:

47.6 lbs / 21.6 kg

Approximate weight savings:

20.6 lbs / 9.3 kg

This is a significant reduction at the rear of the vehicle while simultaneously replacing the headers, catalyst assemblies, muffler, valves, and associated factory exhaust hardware. SOUL Performance Products

MODULAR CATALYST SECTIONS:

The Race Exhaust is designed so the catalyst section can be changed independently of the headers and rear exhaust.

Owners can therefore switch between:

Competition – No Catalytic Converters

• Maximum exhaust flow

• Minimum system weight

• Maximum exhaust volume

• Maximum motorsport character

• Approximately 42.9-lb complete system weight

300-Cell High-Flow Catalytic Converters

• Retains catalytic converters

• SOUL-designed 300-cell catalyst cores

• Custom-specified precious-metal catalyst coating

• Triple-metal-matrix core construction

• Reduced exhaust volume compared with the catless configuration

• Approximately 47.6-lb complete system weight

The modular architecture also allows replacement catalyst or catless sections to be purchased later without replacing the headers or rear X-pipe assembly. SOUL Performance Products

ELECTRONIC VALVE SIMULATORS:

The factory 992 GT3 uses electronically actuated exhaust valves.

These actuators cannot simply be unplugged or removed when installing a non-valved race exhaust.

SOUL states that removing the factory valve actuators without properly simulating their operation can trigger a check engine light and place the vehicle into a reduced rev limiter of approximately 6,000 RPM.

The Race Exhaust therefore includes dedicated valve simulators.

The simulators plug into the factory valve wiring and allow the original exhaust valves and actuators to be removed without creating the valve-related fault condition.

CHECK ENGINE LIGHT:

Both Race Exhaust configurations replace the original Porsche catalyst assemblies.

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

European-specification vehicles require an appropriate OBD device or ECU calibration to address resulting diagnostic faults.

Customers should not assume that selecting the high-flow catted configuration guarantees factory-equivalent emissions-monitoring behavior.

EXHAUST TIP OPTIONS:

The Race Exhaust is available with two 4-inch single-wall exhaust-tip styles:

• 4" Slash Cut Single Wall

• 4" Straight Cut Single Wall

Each tip style is available in:

• Signature Satin

• Brushed

• Satin Black

The tip design does not change exhaust-system performance, allowing the customer to select the appearance that best matches the vehicle.

EMISSIONS / COMPETITION USE NOTE:

The SOUL Race Exhaust System replaces the factory emissions hardware and is not CARB certified.

SOUL identifies this system as intended for closed-course competition use only where required.

The Competition configuration completely removes the catalytic converters.

The high-flow catted configuration also replaces the original Porsche catalytic converters with aftermarket components.

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