i have the greddy sp2 exhaust, but thats not the full exhaust system..what does full exhaust come with? headers, y pipe, test pipe?? is that what they mean by cat-back? Would that be stupid if i bought the headers now seperately with the test pipe? and maybe plenum spacer/ sorry for the noob question lol

 

no the exhaust means that it goes from the cat...back. I would suggest getting headers y pipe and test pipes, it would add quite a bit more performance

 

OK - if you want the most performance - get hi perf cats or resonated testpipes and a catback system - don't get headers - waste of money unless you are fully building your car NA or going FI with a super charger.

We sell a great catback and resonated testpipes as well...but do your self a favor and save a bunch of money - don't do headers unless you have specific build reasons to.
