Hey ppl, just wondered if you could give me some advise on the standard exhaust set up on my 2006 S4.
It sounds decent as standard, but would like it slightly louder if poss without going down the Milltek route of a cat back system.
Was chatting to a mate of a mate and said i could poss remove the pre cats and resonator before the rear boxes to increase the lovely V8 sound track
Just wouldnt want to remove both and it sound like tank after its been done.
Gather from what ive heard is the system has main cats, then pre cats and resonator before the rear boxes ???
Any help/pointers would appreciate it
