So I'm thinking about getting a custom exhaust put on my 96 GT. Currently I have Flowmaster delta 40 cat back (2 1/4in) on which are quieter that I like. I have a few questions though. I live in California
so we have smog tests
so I'm keeping my stock cats in place and having them weld on a custom 3in xpipe.
My first question is, will this make any difference in sound or performance? Or should I just leave the stock hpipe in place.
I also want to replace the mufflers with 3in Cherrybomb Glasspacks.
Overall if I put the custom xpipe(with the stock cats still there), all new 3in piping and the 3in Cherrybomb Glasspacks, would it be louder than my current set up or am I just wasting my money. Sorry for being such a noob, and thanks in advance!
