Replaces the restrictive factory catalytic converters with much less restrictive straight-through pipes for maximum flow and performance
You wouldn't believe the incredible sound hiding within your Cayenne's exhaust system. Our Secondary Catbypass Pipes remove the restrictive unmonitored secondary catalytic converters to increase power and entice an incredible V8 sound from the tailpipes. Enjoy a great tone with no check engine light - there's a reason they are our number one selling product for Porsche!

I had them installed on my 2016 CTTS at a Porsche dealership yesterday. I have the factory sport exhaust. OMG, what a sound with exhaust button on!
Pops and crackles are unreal on the downshift and deceleration. Great sound at cruise speed, too. Even a throaty growl with exhaust button off, but very pleasant. Clearly not an option for those looking for a quiet ride.
