Porsche 992.2 Carrera GTS / Carrera 4 GTS / Targa 4 GTS SOUL Competition Exhaust System

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.

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.
