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

• No GPF

• Full 3.5-inch turbo-back system

• Non-valved

• Maximum exhaust flow

• Maximum turbocharger sound

• Lower system price

• Engineered for greater factory-ECU integration

• Manufacturer-tested at 50+ whp / 40+ lb-ft on factory software

The two systems share the aggressive 3.5-inch rear exhaust philosophy, but differ primarily in the downpipe and emissions configuration.

COMPETITION VS. VALVED EXHAUST PACKAGE:

Competition Exhaust

• Catless

• Non-valved

• Full 3.5-inch rear exhaust

• Maximum flow

• Maximum sound

• ECU calibration mandatory

• Competition-oriented configuration

Valved Exhaust Package

• SOUL 300-cell Sport Cat

• Factory electronic exhaust-valve integration

• 3-inch valves-open rear path

• Quiet and aggressive operating modes

• Better suited to mixed street and performance use

• Manufacturer-reported 40+ whp

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:
Approximately 11.5 lbs / 5.2 kg

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

• Approximately 15.9 lbs lighter than factory

• Check engine light without tuning

• ECU tune mandatory

• Off-road / competition-focused configuration

Sport Cat Downpipe

• SOUL 300-cell performance catalyst

• Factory GPF removed

• More street-oriented configuration

• Engineered GPF-monitoring provisions

• Approximately 16.75 lbs

• Approximately 10.65 lbs lighter than factory

• Engineered to minimize CEL potential on an otherwise untuned vehicle

• Higher purchase price

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:

• Porsche 992.2 911 Carrera 4 GTS Coupe

• Porsche 992.2 911 Carrera 4 GTS Cabriolet

• Porsche 992.2 911 Targa 4 GTS

Package Includes

• SOUL Sport Cat Downpipe

• SOUL Valved Exhaust System

• High-flow 300-cell catalytic converter

• Integrated harmonic-dampening resonator

• Required installation hardware

• Resonator heat shield

• New turbo gasket

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.

Weight Reduction

The individual components provide substantial weight savings compared with their factory counterparts.

Sport Cat Downpipe

• Factory: approximately 27.4 lbs

• SOUL: approximately 16.75 lbs

• Savings: approximately 10.65 lbs

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.

PERFORMANCE EXHAUST VS. SPORT CAT DOWNPIPE:

Sport Cat Downpipe

• Replaces factory downpipe only

• Retains factory rear exhaust

• Retains factory electronic exhaust valves

PERFORMANCE EXHAUST VS. VALVED EXHAUST:

Performance Exhaust System

• Complete turbo-back system

• Sport Cat Downpipe included

• Full 3.5-inch rear exhaust

• Non-valved

• Maximum flow

• Aggressive sound at all times

• Best suited to customers prioritizing performance and constant exhaust character

Valved Exhaust System

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

SOUL specifically lists the VTA Charge Pipe for all 992.2 Porsche 911 Carrera GTS models from 2025 onward worldwide. SOUL Performance Products

DETAILS:

• Converts the factory boost-release system to a Vent-To-Atmosphere / VTA configuration

• Produces an audible “whoosh” sound during throttle lift

• Relocates the factory valves from the original intake tube onto the SOUL aluminum charge pipe

• Every assembly is quality-controlled and fixture-tested before shipment

• Foam-packed after final inspection

• Designed and manufactured in-house by SOUL Performance Products in Willow Grove, Pennsylvania

• Backed by SOUL's Lifetime Warranty for street and track use 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

This preserves the factory electronically controlled hardware while producing the desired VTA behavior.

SPEED-DENSITY ENGINE MANAGEMENT:

Vent-to-atmosphere systems can create drivability problems on vehicles using a traditional mass airflow sensor, because air that has already been measured by the ECU may subsequently be discharged before reaching the engine.

The 992.2 Carrera GTS operates differently.

SOUL states that the GTS calculates airflow using a speed-density strategy based on volumetric efficiency, meaning the system does not depend on recirculating the released charge air in the same way a traditional MAF-equipped vehicle would.

This is why SOUL can use a true VTA configuration without the fueling issues commonly associated with venting metered air.

SOUL reports long-term testing of its development vehicle with zero issues. SOUL Performance Products

NO CHECK ENGINE LIGHT / NO TUNE REQUIRED:

SOUL specifically states that the VTA Charge Pipe requires:

No ECU tune

No OBD killer device

and is designed to operate without a check engine light.

The system retains and relocates the factory valve hardware rather than attempting to electronically delete it.

This makes the VTA Charge Pipe a straightforward bolt-on modification for customers primarily seeking additional turbocharger character and improved charge-pipe construction. SOUL Performance Products

BOOST RESPONSE:

SOUL states that rapidly releasing pressurized charge air during throttle lift can improve response during subsequent throttle application.

Traditionally, vent-to-atmosphere systems can also help the turbocharger maintain compressor-shaft speed during throttle transitions rather than forcing the compressor to work against trapped pressure.

SOUL specifically notes this benefit as particularly relevant to the hyper-responsive eTurbo operation of the 992.2 Carrera GTS. SOUL Performance Products

SOUND CHARACTER:

The most immediately noticeable change from the VTA Charge Pipe is acoustic.

Expect:

• Distinctive vent-to-atmosphere “whoosh” on throttle lift

• Greater audible turbocharger activity

• More mechanical interaction between driver inputs and the turbo system

• Stronger perception of boost-release events

• More engaging turbocharged character without changing the exhaust system

The VTA Charge Pipe affects charge-air / turbo sound, not exhaust volume.

It can therefore be installed independently of the factory exhaust, SOUL Sport Cat Downpipe, or SOUL rear exhaust system.

6061 ALUMINUM CONSTRUCTION:

SOUL replaces the flexible factory hose section with hand-welded 6061 aluminum piping.

The rigid aluminum construction eliminates the flexing associated with the factory rubber hose while providing a durable foundation for the relocated factory valves.

The tubing features bead-rolled edges to help securely retain the silicone couplers under boost pressure. SOUL Performance Products

CNC-MACHINED BILLET PORT BLOCK:

The factory valves mount to a precision-machined 6061 billet aluminum port block incorporated into the SOUL charge pipe.

Using a machined billet component allows SOUL to accurately control:

• Valve mounting geometry

• Port dimensions

• Sealing surfaces

• Component alignment

• Structural rigidity

The port block forms the interface between the factory electronic valves and the new VTA charge-pipe architecture.

SILICONE HOSES & T-BOLT CLAMPS:

SOUL includes multi-ply silicone hump hoses and heavy-duty T-bolt clamps with the kit.

The hump-style couplers allow additional controlled movement between the rigid aluminum pipe and surrounding powertrain components.

This provides flexibility for normal engine movement and thermal expansion while retaining the benefits of the rigid aluminum charge-pipe assembly.

COMPLETE KIT:

The VTA Charge Pipe includes the hardware required for installation, including:

• Hand-welded 6061 aluminum charge pipe

• CNC-machined 6061 billet valve port block

• 3D-printed TPU port plugs

• Factory charge-pipe feed-line cap

• Multi-ply silicone hump hoses

• T-bolt clamps

• Required installation hardware

SOUL fixture-tests every assembly before shipment to verify fitment.

Product Description

The SOUL Sport Cat Downpipe is designed specifically for the 992.2 Porsche 911 Carrera GTS T-Hybrid platform, targeting one of the most restrictive sections of the factory exhaust system while retaining a high-flow catalytic converter.

Porsche's 3.6-liter T-Hybrid powertrain uses a high-flow electrically assisted turbocharger / eTurbo, but the factory exhaust gases must pass through a large Gasoline Particulate Filter and restrictive catalytic-converter assembly immediately downstream. SOUL replaces this assembly with a significantly freer-flowing downpipe built around a SOUL-designed 300-cell performance catalyst and a purpose-engineered 316L stainless steel 3D-printed turbo inlet.

The result is substantially reduced post-turbine restriction, noticeably greater turbocharger sound, stronger engine character, improved response, and significant weight savings while retaining a catted exhaust configuration.

The complete SOUL Sport Cat Downpipe weighs approximately 16.75 lbs, compared with approximately 27.4 lbs for the factory assembly, saving 10.65 lbs / 4.8 kg. SOUL Performance Products

992.2 GTS T-HYBRID EXHAUST ARCHITECTURE:

The 992.2 Carrera GTS uses Porsche's new T-Hybrid powertrain architecture rather than the conventional twin-turbo arrangement used by earlier Carrera GTS models.

At the heart of the system is a single electrically assisted exhaust-gas turbocharger.

The electric motor integrated into the turbocharger allows the turbine to accelerate much more rapidly than a conventional turbocharger, significantly reducing the lag that would normally accompany the large exhaust-flow cross-sections required by the engine.

This gives Porsche the ability to move substantial exhaust mass through the turbocharger while maintaining extremely quick boost response.

SOUL identified the exhaust hardware immediately downstream of the eTurbo as a major restriction in that otherwise high-flow system. SOUL Performance Products

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 exhaust exits the eTurbo, it must pass through a large approximately 8-inch GPF assembly and restrictive catalytic converter.

The substantial cross-sectional restriction limits how efficiently the gases can move away from the turbine.

SOUL's Sport Cat Downpipe removes the restrictive GPF section and replaces the catalyst architecture with a much freer-flowing performance configuration. SOUL Performance Products

300-CELL PERFORMANCE CATALYST:

At the center of the SOUL downpipe is a SOUL-designed 300-cell catalytic converter.

The catalyst incorporates:

• 300-cell construction

• Custom-specified precious-metal coating

• Triple-metal-matrix core construction

• High-flow architecture

This allows the system to retain a catalyst while substantially reducing restriction compared with the factory downpipe assembly.

3D-PRINTED 316L TURBO INLET:

SOUL uses next-generation metal additive manufacturing to produce the downpipe inlet.

The inlet is 3D printed from 316L stainless steel and specifically engineered to optimize the transition from the eTurbo into the catalytic converter.

Metal 3D printing allows SOUL to create internal geometry that would be difficult or impossible to reproduce using conventional cut-and-weld fabrication.

The resulting inlet is designed around efficient flow directly into the catalyst core. SOUL Performance Products

FACTORY GPF MONITORING INTEGRATION:

Removing the factory particulate-filter section introduces an important electronic challenge.

The Porsche ECU monitors the operation of the factory GPF system, including exhaust-pressure behavior.

SOUL engineered provisions into the Sport Cat Downpipe to replicate the factory GPF pressure differentials while also accounting for factory oxygen-sensor behavior.

The goal is to minimize the likelihood of diagnostic faults on an otherwise untuned vehicle.

SOUL specifically describes this as helping minimize the potential for a CEL, rather than providing an unconditional no-CEL guarantee. SOUL Performance Products

TURBO RESPONSE / DRIVABILITY:

Reducing restriction directly downstream of the eTurbo allows exhaust gases to leave the turbine more efficiently.

SOUL reports:

• Better response under all operating conditions

• A noticeably harder pull throughout the power curve

• Greater turbocharger sound

• Increased overall exhaust character

Because the T-Hybrid system can spool the electrically assisted turbo extremely quickly, the freer-flowing downstream exhaust allows more of the system's available flow capability to be utilized.

SOUND CHARACTER:

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

Expect:

• Significantly greater turbocharger sound

• Much more noticeable boost / spool volume

• Stronger flat-six engine character

• Increased exhaust presence

• Deeper exhaust tone

• A relatively subtle increase with the exhaust valves closed

• A considerably more noticeable increase with the valves open

• Minimal additional cold-start disturbance because the factory valves close almost immediately after startup

SOUL also reports that undesirable cabin presence remains extremely low across the different valve modes. SOUL Performance Products

WITH FACTORY VALVED EXHAUST:

The Sport Cat Downpipe can be installed while retaining the original Porsche rear exhaust system.

This configuration provides:

• Significantly greater turbocharger sound

• Reduced upstream exhaust restriction

• Greater engine character

• Retention of factory electronic valve operation

• Controlled cruising volume

• A straightforward first-stage upgrade without replacing the rear exhaust

For customers modifying the car progressively, the downpipe can therefore be installed before upgrading the rear exhaust.

WITH SOUL VALVED EXHAUST:

Pairing the Sport Cat Downpipe with SOUL's dedicated 992.2 Carrera GTS Valved Exhaust further increases overall exhaust character while maintaining electronically controlled sound levels.

This combination is aimed at customers wanting a substantial increase in sound without committing to a permanently loud non-valved system.

WITH SOUL PERFORMANCE EXHAUST:

The Sport Cat section is also central to SOUL's development work on its complete 992.2 Carrera GTS Performance Exhaust System.

SOUL reports gains of more than 50 wheel horsepower and 40 lb-ft of torque from its complete Performance Exhaust System while retaining the factory ECU software.

SOUL states that the majority of those gains result from the increased efficiency of the Sport Cat section.

These figures are for the complete Performance Exhaust System, however, and should not be advertised as isolated Sport Cat Downpipe gains. SOUL Performance Products

WEIGHT SAVINGS:

Factory Downpipe Assembly:
Approximately 27.4 lbs / 12.4 kg

SOUL Sport Cat Downpipe:
Approximately 16.75 lbs / 7.6 kg

Weight Savings:
Approximately 10.65 lbs / 4.8 kg

That represents roughly a 39% reduction in downpipe assembly weight.

The weight is removed from the rear portion of the vehicle while simultaneously improving exhaust flow.
