I love my borla...I have BBK shortys cuz of emissions.
theres alot of setups. Headers look at: Kooks, Hooker and Jet hot
Exhausts: SLP LM, Borla, Corsa, Tsp ....depends on how loud u want.. I know the Loud mouth with the resonator out and a borla Xr1 sounds good. Cat wise depends. whatever headers you choose you might want an OryPipe

so the headers are going to come with bolts and gasket most likely right am i going to need a pipe from there to the cat and an orypipe

they just replace ure stock manifold, gaskets and Bolts ure on ure own for.... Earls with stage 8 locking are good to get. the bolts and gaskets most companys give you suck anyway..

whats an orypipe and is there a y pipe before the cat that i need to get and do i need to get a highflow cat

archemedes

orypipe is off road y pipe the one in front of cat, a high flow cat won't hurt, but I doubt you'll notice a difference unless your cat is bad, the new stock ones flow as well or better than all the aftermarket ones

Yep 12 hp gain or whatever is BS. ObD II cars that is

I think the good ones started around '95 on gm cars (I read it somewhere a year or 2 ago)

3inches is good. More air in more air out type of thing!
