Soul Performance Products was asked to deliver an exhaust solution that increases volume and flow without taking the step up to spending thousands of dollars on upgraded headers. The Center Muffler Bypass increases the invigorating flat-six tone that you love without sacrificing comfort during daily driving. Retaining the stock side mufflers and valves allows you to control the sound with the factory sport button. This exhaust also pairs well with headers for those looking for the ultimate track setup in terms of power and sound – and we back track use under our Lifetime Warranty! No check engine lights occurred during both development and long term road testing. We offer a variety of tip options ranging from hand-built carbon fiber tips to attractive single wall stainless steel tips. For 991 GT3 applications, we recommend 4″ tips to fill out the bumper, but 3.5″ tips are available by request.

CONSTRUCTION:  Each system 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 and Carbon Fiber Tips). Projection welding spots, swinging bridge, high-strength stainless steel bolt and the exclusive design of the captive nut and trunion offer superior clamping forces and longevity. AccuSeal clamps are included to connect the exhaust to the side mufflers.

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

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 issues that you may have.

    Fantastic! Can’t imagine driving without it now.

    Their exhaust is incredible! The sound is fantastic, no drone what so ever in the cabin. I couldn’t be happier !

    These guys are awesome. I wanted a muffler bypass for my 911R and I’ve always thought the cost of bypass pipes have gotten ridiculous for what they are. I called up Soul Performance and they had one of theirs out to me within the next couple days. The price was incredibly reasonable (almost a third of competitors)…build was great, fit was great and the sound…well the sound is just unreal. I’d recommend them for anything.
