will this fit?
Honestly can't see much of a sound difference, muffler is almost the same. Slightly larger piping, but not worth the hassle if you're doing it for performance. The SS tip looks much better though
the stock ls exhaust is a 2" exhaust it actually does a decent job as far as gains and is much cheaper then an after marketsystem
i guess im more concerned with sound difference, im not fooling myself its only a LS... i would just like a deeper sounding tone, no ricer effect
I gained 3hp going from a stock LSJ catback to a GMPP one. There isn't power to be had in a catback on these cars. Header/dp is where the restriction is.
