am i better off just buying a full exhaust system like greddy evo2? or working on what i have ( greddy sp2 cat back, injen cai) and adding a y pipe, race/test pipes/mid pipes/headers etc. ?? will this cost more in the long run? thanks

 

I have almost the same set up. I just got test pipes on today and the car feels more free and the sound is bad a**. Little rasp between 3k-4k rpm. but the rasp is very minimal. I am going to sell my greddy sp2 and am getting a full catback exhaust so I think the rasp will be completely gone.

 

get some headers and test pipes
