Probably? Ehh, I was searching and i was reading this one thing where it said the a4 Exhaust is not to restrictive and changing the piping will really serve no purpose is that true? That was about the 12V though?

A little bit of help here.

 

Seems most people with the 30V engine just do the axle-back setup, from what I've seen. The full cat-back looks and sounds great, but it is expensive, and I think I remember seeing the advice here that on a non-SC'ed 2.8, just do the axle-back and save the money - it'll get you a great sound, nice look, and might make some power to boot.

 

I'm pretty sure after the exhaust manifolds everything on the 12v and 30v is the same. If not I bet an exhaust shop could easily modify it to work.
