On the tt forum the majority love there exhaust for sound and fitment. I have had mine for a year, ordered directly from Britian and had it in under 2 weeks. Probably not going to see much of a power increase on a Cat back although I heard on the RS246 list that this was a non-resonated good sounding exhaust so that probably opens it up for a little more free flowing. Guy also said it sounds great. My tt one sounds great, only slightly louder than stock and no resonance, some aftermarket exhausts can be loud and annoying which would be a definite no on a car of the RS6's caliber. I may wait for sound clip or more feedback but it is a great price and a manufacturer with a great reputation.
