DEVELOPMENT AND TESTING:  Soul Performance Products was asked to deliver a custom exhaust system solution that increases volume and flow without taking the step up to spending thousands of dollars on upgraded headers. Retaining the stock side mufflers and valves allows you to control the sound with the factory sport button. This exhaust also pairs well with upgraded headers for those looking for the ultimate track setup in terms of power and sound – and it’s backed for track use under an industry leading Lifetime Warranty! 

CONSTRUCTION:  Each system is made from mandrel-bent T304L stainless steel tubing. New brackets and hardware are included to mount the system. AccuSeal clamps are included to connect the exhaust to the side mufflers. 

BOLT ON AND GO:  Each exhaust system is tested in a fixture to ensure perfect fitment and then foam packed to ensure it arrives in perfect condition. The Center Muffler Bypass Exhaust is a straightforward install that can be performed by most DIY enthusiasts.

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

    Switched from another brand’s center delete to the Soul Performance version and couldn’t be happier! The black tips fill out the 997 GT3’s rear valence perfectly and the car has an extremely aggressive tone with the valves open but once closed, the car is as tame as factory. It really is the perfect solution.

    Very pleased, good fit and build quality. Sounds awesome. Loud but very livable as a daily driver with no drone.

    I recently installed the Soul Performance muffler bypass on my GT3. The stock sound is amazing as we know, but I wanted a little more grunt. Installation was relatively easy if you have a lift. I did it with a help of a friend and we completed the job in 2 hours. Most of that time was taking the stock muffler off. We did it without removing the bumper but it would be much easier with the bumper removed. The key is to loosen the clamps to the cats as well as to the side mufflers so you have enough play in the system to remove and install everything. Otherwise, pretty straightforward. I went with 88mm black slash-cut tips. It’s a nice piece of kit and I highly recommend this mod. Lastly, there is some video and audio with the bypass installed.
