Side Muffler Bypass Pipes.



Optimized design that replaces the heavy and restrictive factory side mufflers for improved exhaust flow, increased sound and weight savings.

Utilizing premium Helical valves along with the addition of O2 bungs, Fabspeed's Side Muffler Bypass Pipes provide the ultimate track solution for the 991.2 GT3 / GT3 RS. When accompanied with our new Long Tube Competition Headers, our Side Muffler Bypass Pipes allow the maximum amount of exhaust flow possible from the 991.2 GT3 / GT3 RS engine.

HELICAL VALVES

We chose to use Helical Valves on our 991.2 GT3 / GT3 RS track exhaust systems for their unprecedented quality - which have been proven by many OEM manufacturers such as McLaren, Ferrari, Lamborghini, and many more. Helical valves are an integral part of our Side Muffler Bypass pipes, opening and closing with precision to control the gas flow and optimizing engine back-pressure for improved performance. Helical's extensive experience in high-volume OEM automotive applications has led to standard features such as an extremely durable pneumatic actuator, precision flat sealing faces inside the valve, stiffening ribs and high-temperature bearings at both ends of the butterfly spindle.

O2 BUNGS

We relocated the O2 bungs from the collector of the headers to the Side Muffler Bypass Pipes in order to maintain factory-like functionality with our Long Tube Competition Headers - allowing them to read all cylinders while maximizing the performance of the collector. This design will replace our existing SMBP's allowing you to upgrade to our Long Tube Race Header design at any time in the future.

FEATURES:

• Fits all Porsche 991.2 GT3 / GT3 RS vehicles (2017+)
• Highest quality Helical valves
• Includes O2 bungs for factory like functionality when paired with Fabspeed Long Tube Competition Race Headers
• Saves 34 lbs from the rear of the vehicle
• Replicates aggressive CUP car sound for the street
14-16ga T304 Stainless Steel construction
• Simple bolt-on installation

• All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty.

Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

SOUL Catted Race Exhaust System   Porsche 992 GT3 / GT3 RS

Built for maximum power and sound for the 992 GT3 and GT3 RS 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.

•  Fits all Porsche 992 GT3 / GT3 RS models (2022+), and 991 Speedster 
•  Weighs up to 25.3 lbs / 11.4 kg less than factory exhaust components (68.2 lbs vs 42.9 lbs catless / 47.6 catted)
•  Modular cat sections allows swapping from catted to catless
•  Valve simulators allow for removal of factory valves without throwing a check engine light!
•  All Soul Performance Products exhaust components are backed by the industry’s first and finest Lifetime Warranty for both street and track use
•  Designed and built in-house at our Willow Grove, PA facility

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. 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, and emission 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.

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. 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.
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. We have engineered valve simulators to allow removal of the valves! Simply plug the simulators into the factory valve harnesses and expect no check engine lights or issues!

SOUND
The SOUL Race Exhaust System transforms the 992 GT3’s sound into an authentic Cup Car experience. The X-pipe blend produces a higher-pitched, motorsport-style wail, delivering race-ready volume and tone that’s extreme for street use but perfectly suited for track driving. The result is an authoritative, spine-tingling exhaust note worthy of Porsche’s GT racing heritage.

POWER
Dyno testing conducted by Hydra Motor Works revealed substantial power gains:
•  +23 whp / +19 ft-lbs torque with the SOUL Race Exhaust System alone
•  +60 whp / +26 ft-lbs torque peak gains with the addition of a Hydra Stage 2 ECU tune
•   Maximum observed gains: over +60 whp / +70 ft-lbs torque

These are exceptional results for a naturally aspirated engine—transforming throttle response, midrange pull, and top-end performance.

CONSTRUCTION
Each component is handcrafted in the USA from mandrel-bent .065″ wall T304L stainless steel. The billet 304L stainless steel head flanges and merge collectors are precision-cut on a 5-axis CNC machine for superior flow, strength, and accuracy. All joints are TIG welded and back-purged with ARCAL™ Prime argon gas to ensure perfect weld penetration and long-term durability—essential for demanding track conditions.

CHECK ENGINE LIGHT
Because the factory catalytic converters are removed, this system may trigger a CEL. For competition use, an ECU calibration or tune is recommended.

LIFETIME WARRANTY
All SOUL exhaust components are backed by a Lifetime Warranty covering both street and track use. Our team provides prompt and professional support to resolve any issues or answer questions.

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

Please note: sports catalytic converters or bypass pipes do have type approval and may not be legally installed on vehicles manufactured after 1st March 2001. They can not be used on a public road and are not MOT compliant, they are designed for race and track cars only.

Please note: This item is not a stock product. It is a special order part and once ordered with us is not subject to cancellation or return unless proven not fit for purpose or defected.
