with a S4 catback exhaust? I ask because i dont think iv seen a 2.8 exhaust as big as the S4 exhausts...it would make sense in my eyes for more flow.. and yes i know they dont fit perfectly but you can get them to fit on the 2.8's

Why not just buy a Milltek and call it a day? Would sound better, as well, and you'd save yourself fitment/adjustment headaches.

The S/C exhaust game is also much closer to the naturally aspirated exhaust school of thought...and very different than that for a turbo car.

i ahve the s4 catback on my 2.8. it was slightly bigger then the stock, does seem to flow better, but as you said, ive never been able to fit it properly. i can't get the slips to seal 100% at the middle point where the stock 2.8 cats meet up with the s4 catback. im getting rid of my s4 catback in place of the factory. but i would think that the s4 would be great for a S/C. and cheaper. much cheaper then the milltek.
