if i keep my car

im going 2.5" catback... LSJ header

2.5 will consist of... OMG 2.5" piping!!!

a thrush (sp) glasspack for a resonator, and a magnoflow 40 series for end muffler...


all i need now is a way to hang it

to much work... just get a catback exhaust.. i got the DC sports it just bolts on and only cost me $375

where'd you find it for $375?

2.5 in my opinion might be slightly larger than you really need and will effect your exhaust velocity negatively. Stick with a 2 1/4" exhaust diameter.

it was on sale at Nopi.com

GM's exhaust is mandrel bent 2 1/4"
