Hey guys, just got an 01 s4, so looking at modding it a bit, it'll have the warranty so i don't want to chip it (yet). I was looking at cat-backs, and there's a big difference in the overall prices, but i was wondering what hte best bang for buck is...

How is the borla cat-back? or how about the neuspeed? Just looking for something to add some power and a nice note.

your best bet is borla. i heard good things. if u like go to cardomain.com and see what cat-back exhaust other audi s4 owners use and what they say about it

 

borla is good, if your looking for a quality sound try milltek, a bit picey but it is well worth the money.
