SLP Y-Pipe, is it worth it ????
What is the biggest restriction in the exhaust, other than the muffler (I have the loudmouth)??
Thanks!!
Having said that, I have an SLP Y-pipe that I put on when I installed my last catback. It's a nice piece, but I doubt the gains are very big. I'm sure there is some gain though, especially for me since I'm running race pipes in place of the cats.
