Porsche 992.2 GT3 / GT3 Touring SOUL Race Exhaust System

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.

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.
