DEVELOPMENT AND TESTING: SOUL was approached to create an exhaust solution to maximize the sound and weight reduction of the exhaust system while maintaining reasonable cabin presence and investment. We took this one step further by making this solution modular by combining our side and center muffler deletes. This means you can easily mix and match the system with the factory center muffler or side mufflers to experiment with different sound characteristics of the car and reduce or increase overall sound level. As deleting the factory center and side mufflers at the same time inherently deletes the factory support brackets, we created Porsche 991 GT3 / GT3 RS / 911R Modular Competition Exhaust Package brackets for this combination of components.
This system is available in a non-valved and valved configurations. The valved configuration maintains factory PSE button control. With valves closed, 100% of the exhaust is channeled through smaller diameter piping before entering the expansion chamber of our center muffler bypass. This will make a notable difference in sound level on the exterior of the car, though will be less noticeable in the cabin of the car. The expansion chamber design of our center muffler does a great job at reducing drone/vibration in cabin, and has the most reasonable cabin presence of any “straight pipe” headerback/catback configuration we have experienced on the GT3 platform.
Porsche 991 GT3 / GT3 RS / 911R Modular Competition Exhaust Package CONSTRUCTION:
Each exhaust component is made from mandrel-bent T304L stainless steel tubing. Mikalor Supra Heavy-Duty W4 Clamps are included to mount the system to the vehicle (also included to mount Single Wall tips). Projection welding spots, swinging bridge, high-strength stainless steel bolt and the exclusive design of the captive nut and trunnion offer superior clamping forces and longevity. AccuSeal clamps are included to connect the exhaust to the side mufflers. A variety of exhaust tip options ranging from double wall tips to attractive single wall stainless steel tips are available. Logo customization – or no logo at all is optional – contact us for something special. The 991.2 tips are longer due to the difference in rear bumper depth from the .1 model, providing perfect fitment for all years.
BOLT ON AND GO: Each exhaust component is tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition. We include plugs for the vacuum lines for those running the non-valved setup. Installation is straight forward and can be performed by most DIY enthusiasts. No check engine lights are associated with this system as the o2 sensors are located in the headers.
