Porsche 991.2 GT2 RS SOUL Competition Race Pipes

Product Description

The SOUL Competition Race Pipes are the most aggressive exhaust configuration offered for the 2018–2020 Porsche 991.2 911 GT2 RS, replacing the factory catalytic converters, exhaust valves, and muffler architecture with an ultra-lightweight, completely catless and valveless straight-pipe system.

Unlike SOUL's Cat Bypass Pipes, which retain the factory exhaust valves and rear muffler, the Competition Race Pipes eliminate the GT2 RS's dual-mode exhaust architecture entirely. Exhaust flows directly from the turbocharger area toward the rear outlets without catalytic converters, ECU-controlled valves, or the factory muffler system.

The result is maximum turbocharger presence, an extremely aggressive 3.8L twin-turbo flat-six exhaust note, substantial reduction in exhaust restriction, and one of the largest weight reductions available within the SOUL GT2 RS exhaust lineup.

The complete SOUL Competition Race Pipe assembly weighs approximately 8.3 lbs, compared with approximately 29.2 lbs for the factory components it replaces, removing approximately 20.9 lbs / 9.4 kg from the rear of the GT2 RS.

FULL RACE EXHAUST ARCHITECTURE

The Competition Race Pipes are fundamentally different from the Cat Bypass Pipes we just cataloged.

The Cat Bypass Pipes remove the catalytic converters but retain:

• Exhaust valves

• Factory ECU valve control

• Factory rear muffler

• Quiet valves-closed operation

The Competition Race Pipes eliminate:

• Catalytic converters

• Exhaust valves

• ECU-controlled valve operation

• Factory muffler routing

The result is a fixed, straight-through exhaust path intended to maximize sound, flow, simplicity, and weight reduction.

CATLESS

The Competition Race Pipes completely remove the original Porsche catalytic converters.

This eliminates the catalyst substrates immediately downstream of the turbochargers and allows exhaust gases to flow through a substantially less restrictive path.

Benefits include:

• Maximum catalyst-section flow

• Increased turbocharger sound

• Increased exhaust volume

• Reduced exhaust-system mass

• Greater performance potential on modified vehicles

This configuration also introduces the emissions, exhaust-odor, and diagnostic consequences associated with removing the factory catalysts.

VALUELESS DESIGN

The factory GT2 RS uses ECU-controlled exhaust valves to vary how much exhaust flows directly toward the tips versus through the factory muffler system.

The Competition Race Pipes remove that functionality entirely.

There is:

No valves-open mode.

No valves-closed mode.

No ECU-controlled exhaust-volume change.

The race exhaust path is active continuously.

NO FACTORY QUIET MODE

This distinction is particularly important for GT2 RS customers.

With SOUL's:

Cat Bypass Pipes

or

Sport Catalytic Converters

the factory valves and muffler continue providing a comparatively restrained valves-closed mode.

With the Competition Race Pipes, that capability is removed.

Customers should expect the car to remain aggressive at all times.

EXTREMELY LOUD

SOUL explicitly warns that the Competition Race Pipes are:

very loud.

This is a straight-pipe race configuration on a 700-horsepower twin-turbo GT2 RS.

Expect a dramatic increase in:

• Cold-start volume

• Turbocharger spool

• Turbine sound

• Flat-six engine note

• Acceleration volume

• High-RPM intensity

• Shift-related sound

• Deceleration character

• Overall cabin presence

This is not intended to provide factory-like refinement.

TURBOCHARGER SOUND

Removing both the catalytic converters and the factory muffled/valved architecture makes the turbochargers dramatically more audible.

Expect substantially more:

• Turbo spool

• Turbine whistle

• Boost-related sound

• Throttle-transition sound

• Mechanical turbocharger character

SOUL describes the turbo note as intense essentially all the time rather than only when the factory ECU decides to open the exhaust valves.

3.8L FLAT-SIX SOUND

The Competition Race Pipes also allow substantially more of the GT2 RS engine's combustion and exhaust-pulse character to reach the rear outlets.

Expect a much bolder:

• Idle

• Acceleration note

• Midrange exhaust character

• High-RPM roar

• Gear-change sound

• Deceleration note

The system prioritizes motorsport character rather than acoustic isolation.

TURBOS HELP CONTROL CRUISING DRONE

Despite the absence of mufflers and valves, SOUL notes that the turbochargers themselves provide some acoustic attenuation during steady-state cruising.

Turbocharger turbines naturally interrupt and absorb some exhaust-pulse energy before the gases enter the downstream exhaust system.

SOUL therefore describes cruising resonance as more manageable than might be expected from a completely straight-piped naturally aspirated engine.

That does not mean the Competition Race Pipes are quiet or drone-free.

They remain an extremely aggressive race exhaust.

MAXIMUM FLOW

Eliminating the:

• Catalytic substrates

• Valve assemblies

• Factory muffler path

removes multiple restrictions from the exhaust system.

The resulting straight-through architecture provides substantial exhaust-flow capacity for:

• Factory power levels

• ECU tuning

• Increased boost

• Intake modifications

• Intercooler upgrades

• Turbocharger upgrades

• Higher-output engine builds

20.9-LB WEIGHT REDUCTION

SOUL publishes:

Factory Components:
approximately 29.2 lbs / 13.2 kg

SOUL Competition Race Pipes:
approximately 8.3 lbs / 3.8 kg

Weight Savings:
approximately 20.9 lbs / 9.4 kg

That represents roughly a:

72% reduction

in the weight of the corresponding factory exhaust components.

This is one of the most significant weight reductions within SOUL's GT2 RS exhaust catalog.

WHY THE FACTORY WEIGHT IS 29.2 LBS HERE

The Competition Race Pipe weight comparison should not be confused with the Cat Bypass Pipe comparison.

SOUL's Cat Bypass Pipes replace only the factory catalyst/valve sections and are compared with approximately:

18.3 lbs of factory hardware

The Competition Race Pipes eliminate more of the factory exhaust architecture, so SOUL compares them with approximately:

29.2 lbs of factory components

This is why:

Cat Bypass Pipes save 6.9 lbs

while:

Competition Race Pipes save 20.9 lbs

The two weight figures represent different amounts of factory hardware being replaced.

T304L STAINLESS CONSTRUCTION

SOUL fabricates the Competition Race Pipes from:

T304L stainless steel

with:

.065-inch wall thickness

T304L provides:

• High-temperature durability

• Corrosion resistance

• Structural strength

• Low mass

• Long service life

• Suitability for repeated track heat cycles

MANDREL-BENT TUBING

SOUL uses mandrel-bent tubing to maintain the intended internal cross section through the exhaust routing.

This minimizes unwanted deformation through bends and supports a smooth exhaust-flow path.

CNC-CUT FLANGES

The Race Pipes use precision CNC-cut flanges at the required mounting interfaces.

Accurate flange geometry helps maintain:

• Exhaust sealing

• Proper alignment

• Installation consistency

• Long-term durability

BACK-PURGED WELDS

All welds are back purged during fabrication.

Shielding the inside of the stainless tubing during welding helps provide:

• Cleaner internal weld surfaces

• Reduced oxidation

• Proper weld penetration

• Greater long-term durability

This is especially valuable on exhaust components exposed to sustained track temperatures.

THICK-GAUGE ALUMINUM FABRICATION FIXTURES

SOUL constructs each system in a thick-gauge aluminum fixture.

The fixture helps control heat distortion during fabrication and maintains:

• Flange location

• Pipe alignment

• Outlet positioning

• Repeatable vehicle fitment

FIXTURE-TESTED FITMENT

Every set is tested in its production fixture before shipment.

SOUL then performs a final quality-control inspection and foam packs the components for transportation.

DIRECT BOLT-ON INSTALLATION

The Competition Race Pipes are designed as a bolt-on replacement for the corresponding factory exhaust hardware.

No permanent chassis modification is required during normal installation.

Because this product replaces significantly more hardware than the standalone Cat Bypass Pipes, installation is more involved than a simple rear exhaust-tip or muffler modification.

CHECK ENGINE LIGHT

Because the Competition Race Pipes completely eliminate the factory catalytic converters, the vehicle may detect that catalyst functionality is no longer present.

SOUL states that the system:

may trigger a check engine light.

DasMotoring therefore does not represent this system as CEL-free.

O2 SPACERS

SOUL notes that O2 spacers are available separately to reduce the likelihood of catalyst-related diagnostic faults.

They are not included as part of the standard Competition Race Pipe SKU.

DasMotoring does not represent O2 spacers as a guaranteed CEL-prevention solution.

ECU TUNING

SOUL recommends an appropriate custom ECU calibration for catalyst-related CEL management on competition vehicles.

A tune is not required for the Race Pipes to physically bolt onto the vehicle.

A suitable performance calibration may also allow a modified GT2 RS to take greater advantage of the system's reduced exhaust restriction.

NO PUBLISHED STANDALONE DYNO RESULT

SOUL describes the Competition Race Pipes as producing major increases in exhaust flow.

However, the current product page does not publish a controlled stock-exhaust versus Competition-Race-Pipe dyno comparison.

DasMotoring therefore does not advertise a specific horsepower or torque increase for the system.
