DEVELOPMENT AND TESTING: Soul Performance Products was asked to deliver a exhaust system solution that increases volume and flow without taking the step up to spending thousands of dollars. Retaining the stock side mufflers and valves allows you to control the sound with the factory sport button. This Porsche exhaust also pairs well with upgraded headers for those looking for the ultimate track setup in terms of power and sound – and we back for track use under our Lifetime Warranty! No check engine lights occurred during both development and long-term road testing. We offer a variety of exhaust tip options ranging from double wall tips to attractive single wall stainless steel tips. For 991 GT3 exhaust applications, we recommend 4″ tips to fill out the bumper, but 3.5″ tips are available by request. 991.2 GT3 tips are slightly longer as a result of the change in the bumper.

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 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.

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 parts 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 or answer any questions 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.

    Everything arrived last week and of course I couldn´t resist to install the new exhaust immediately.

    Fitting was easy, I only had to use all available adjustment range downward to ensure enough clearance to the rear bumper. Doing so, it fits perfectly!

    I´m very happy with the outcome…PSE closesd is still neighbour-friendly, open makes you smile from ear to ear, this is what a GT car should sound like.Sound is amazing and the PSE button gives a wider range than in stock trim. Tame and quiet when you want it. Really inspiring when you need it, never annoying. Very good.

    I found the pricing of some other vendors a bit over the top for some welded pipes, and Soul was less than half the price,so I gave it a try.

    Can´t complain at all, fitting was spot-on, sound is just right for my taste and still neighbour-friendly with PSE off, yet absolutely amazing in open mode.
    Since all center deletes are more or less similar in design and dimensions, I wouldn´t expect huge differences in sound anyway.

    Thank you for doing great business!

    Customer satisfaction is their top priority and is what their business is focused around. They’ve taken care of me and my 991 GT3 on numerous occasions. If there’s one reason to consider Soul’s products, besides the price and value, it’s the fact that they go above and beyond for their customers.

    My initial impressions of the new muffler bypass:

    Its absolutely louder. Its a DEEPER tone.
    The transition from Vales closed to valves open is alot more apparent. Where as with the stock muffler it was alot harder to hear the difference.

    There is obviously more resonance within the cabin (that comes with a lounder exhaust)
    But sound is really subjective.

    The overall construction of the exhaust appears to be very nice. I dont know much about welding etc. But the welds do look very nice. Inside the exhaust there are some little gaps between where the two metal surfaces meet. Though i dont think this will affect the performance. There were no gaps on the outside whatsoever.

    I love the finish of the metal. Its very nice. Looks like really really nice quality.

    I do not feel any performance gains ( i didnt expect too by the way- but i was just clarifying for others) I also dont feel any decrease in performance.
