DEVELOPMENT:  The 958.2 Cayenne comes with two sets of catalytic converters from the factory for a total of four restrictive units – upgrading them is a common, cost effective modification. Our goal was to provide a cost effective upgrade while incorporating quality wherever possible. The OEM pipes were first scanned with a ROMER arm, and a bend profile was developed to produce smooth, large radius bends from thick US sourced T304L stainless steel – mandrel bent to strict ISO 9001:2015 quality standards.  You’ll be treated to a fuller exhaust sound without a significant increase in drone. Throttle response and overall drivability is increased.

CONSTRUCTION:  Each set is assembled out of 2.5″ OD, thick-wall .065″ T304L stainless steel and rigorously quality checked in-house. Every cat bypass pipe is built from smooth mandrel bends, thick water-jet cut flanges, and laser cut brackets. Back purged welds ensure proper penetration and overall product longevity. The final pipes are tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition. New hardware is included for the header flanges.

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.

CHECK ENGINE LIGHT?:  This product should not trigger a check engine light as the secondary catalytic converters are unmonitored by the ECU.

    I had my 2017 Cayenne GTS ECU flashed by the guys at Soul Performance (John Gaydos). Had my local mechanic pull the ECU and ship it, took about 48 hours round trip.
    Resulted in noticeably more torque in the lower rev range and smoother shifting. Sounds badass with their exhaust as well. Nice growl at full throttle with no drone. It gets lots of compliments. Well worth it.

    I do want to say that I do love how the car sounds with the pipes. There is more crackles and pops with the car. I do notice that with the OEM pipes, I was getting towards 12 PSI on WOT, but with these pipes, it’s getting close to 15 PSI.

    In terms of interior noise, it isn’t a significant gain, however, once you roll the windows down, you can’t help but hit the gas hard every time.
