Soul Performance Products - Race Exhaust System (992 GT3)

Designed to Fit

• 2020+ Porsche 911 GT3 (992)

Product Details

Built for maximum power and sound for the 992 GT3 with interchangeable cat sections. Long tube runners and CNC’ed merge collectors optimize flow through the headers out to straight 3″ piping with an x-pipe for a higher pitched and smoother sound.

HEADERS

For those individuals looking to maximize performance, shed over 25 lbs, and realize full sound potential a complete race system is a logical conclusion. Removing the heavy and restrictive factory headers is central to the performance improvement. By pursuing a full system replacement we can eliminate the restrictive cat assemblies, the “particulate filters”, and the giant 7 ⅝ connection point to the factory rear muffler assembly. A simple flange optimization to our previous generation GT3 Competition Headers allows us to get rid of the factory 991 gen connection point requiring costly OEM clamps and donut gaskets and utilize a more efficient v-band connection point.

Even a premier engineering masterpiece like the GT3 comes from Porsche fitted with exhaust manifolds restricted in terms of primary tubing length, runner diameter, and merge collection efficiency due to dense catalytic converters, mass production, emissions and sound restriction compromises. By refining the interface between the flange/primary tubes, using smooth radius large diameter bends, and implementing performance oriented collectors with merge spikes, we have been able to achieve increased flow, response, and performance with a more aggressive exhaust note to match. A slip on merge collector was not considered to prevent any chances of exhaust leaks. Instead we focused on designing a high flow collector from CAD to CNC for a no compromise end result. This bespoke billet collector allows for maximized runner length and the elimination of several welds in the interest of durability. Our billet CNC head flanges allow for a more efficient transition from exhaust ports into the runners and adds extra strength in a high stress area preventing the chances for any cracking from repeated, hard use during track days.

REAR EXHAUST SECTION

The rear of the SOUL Race Exhaust System is optimized into a single, full 3″ flow. The design of the factory system includes very large catalytic converters terminating into a very heavy dual entry muffler with restrictive piping with variations throughout the flow path which hinder performance. Those seeking a race setup will appreciate the 25+lbs weight savings and concentration on increasing exhaust flow.

From there we dove into creating a header-back system to maintain maximum flow characteristics with a higher, smoother pitch and aggressiveness akin to an RSR race car. This full 3” diameter system is made from thick .065” wall T304L stainless steel and TIG welded with back purging to ensure it withstands hardcore track abuse. It’s also modular to allow interchanging between catless or high flow catted assemblies with minimal effect on exhaust velocity. Reduce the chance of CELs with 200cell cats and tone down the exhaust if need be as the catless version is without a doubt the loudest and most aggressive system we have ever built. After the catted/catless section, the exhaust flows into an X section where we took care to minimize the diameter reduction while maximizing the blend of the exhaust to create that higher smoother pitch you hear in the videos. Finally a tip plate (same used on 991 GT3’s) allows one to switch between tip assemblies at their convenience.

VALVE CONTROL

The electronic valve actuators can not be simply removed from the valves or else the car will throw a CEL and put it into a reduced rev limiter to 6k rpm. Custom brackets hold the electronic valve actuators to simulate the same start/stop point of the valves in the factory exhaust system. This allows the car to run the non valved exhaust system without any CEL or reduced rev range. 

SOUND

The sound experience of this system on the 992 GT3 is something to behold. The blending of the X gives the car a higher pitched sound befitting of a GT car with authoritative volume to match – on the extreme end for a street driven vehicle. Those seeking a Cup Car experience will be rewarded with an aggressive wail, your face will hurt from the permanent smile.

CONSTRUCTION:  Each component is assembled in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Our billet 304L stainless steel head flanges and merge collector are precision cut on a 5-axis CNC machine for the best possible exhaust flow and strength. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity – crucial for durability on the track. We fabricate the headers and system using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.

HJS HD 200 CELL CATALYSTS:  The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse.

BOLT ON AND GO:  Every set is rigorously quality-checked prior to shipping and then foam packed to ensure your order arrives in perfect condition.

LIFETIME WARRANTY:  Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered for life! Soul covers their HJS catalytic converters with a 3 year warranty while the headers themselves are backed by their lifetime warranty.

NOTE: This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for closed course competition use only.
