I have an 2001 Audi S4 and have been considering this and consistantly interested in this for a long time now. I want to remove my exhaust system and run the pipes through my fenders or a wall of some kind like the M3 RaceCar. If anyone knows anyone who did this before or can give me any suggestions that would be awesome. Thanks Alot

 

BUMP

 

Err, a lot of money for a useless system in my opinion, and you'd have to run one of the exhaust pipes over or under the driveshaft if you want it on one side, I doubt you could cut threw the uni-body and going under it would look weird and cause clearance issues. And the rear bumper would look weird with a hole in it for no reason.
