Deleting the side mufflers yields huge weight savings, helps with heat management in the engine bay, and keeps the rear tires cooler. The hole leading into the secondary pipe is enlarged to equalize pressure in the center muffler – promoting longevity. Flex bellows allow for easy installation and increase durability under extreme racing conditions in a similar manner to OEM. Large 3″ diameter primary piping increases flow. High quality valves operate like factory.

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 bespoke support 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.
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.
LIFETIME WARRANTY: Enjoy your Soul exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any questions or issues that you may have.
