Picked up my second Cayenne few days ago.

My previous Cayenne was 2008 3.6 fabspeed cat bypass with Supersprint race exhaust.

Now I have 3.6 turbo with PSE. I saw on the Macanforum.com that PSE needs minimum 5000 km running in. At the moment the PSE sound is VERY quite compare to my last car.

Fabspeed, IPE or SuperSprint does not have any exhaust options for 958.2 yet

So I went to my local exhaust shop, he can offer cat bypass for US$130 or X pipe (stock is H pipe) US$200.

I am leaning towards cat bypass, will I loose torque on this 3.6 turbo?

 

you would lose exhaust scavenging without the x-pipe/h-pipe, but its probably negligible either way. The x-pipe might also sound a bit better.

make sure you post a video after!
