DEVELOPMENT:  The 958 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 purchased and installed the Soul secondary cat bypass pipes on my 2011 Cayenne Turbo 2 weeks ago and I am very pleased with the result. The exhaust now sounds a little deeper and throatier than it did stock. When in park and revved you can slightly hear the turbos spool. Still very quiet inside the cab, just a little more rumble than before and no drone. When accelerating quickly in sport mode it even has a nice upshift note that it didn’t have prior, similar to the PDK

    I Installed the Soul bypass pipes as well on my 2013 CS.

    The fabrication quality on these is masterful to say the least.

    Sounds wise, on the NA V8 motor with the standard exhuast system, there is a very slight increase in sound in the cabin, zero drone in the cabin.

    Most noticeable thing though, the throttle response is a helluva lot better. Drives way smoother.
