Porsche 992.2 Carrera GTS / Carrera 4 GTS / Targa 4 GTS SOUL Competition Downpipe

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
