I straight piped mine and it sounded like I put Dodge mufflers on it.

I ended up going with a nice straight through design muffler.

I am going to straight pipe my stock exhaust with a 3.5" pipe, but was someday thinking of going 4" or 5" downpipe-back MBRP. Would it be worth it, or will making it straight pipe be better in the long run...I am in CA too
