Ok I got an offroad bassani xpipe sitting in my garage waiting to go on, I was going to just get some mufflers and have the xpipe welded in as well as the mufflers. Would I see much difference in power or sound if I went with a catback kit instead of just mufflers? Also I was thinking of going with bassani mufflers because of the bassani xpipe, any thoughts on that? A local performance shop quoted me 100 bucks to have the pipe and mufflers welded in.
