y-pipe, y-pipe, y-pipe. It is the only thing I've done that made a really noticable difference. I also have the kkm adaptor, so maybe it wouldn't have made as much without that, but those are only $80. Now that I think of it, I also have the bassani. that probably helped too. But your cat back isn't as restrictive as mine was so that wouldn't really matter. Anyway, kkm + y-pipe. You'll be happy
