I Plan on getting the Apexi N1 exhaust system and was wondering which header would be best to go with it??? and intake too..

I would have to say either dc sports or greddy header. They are both around the same price. I would get stainless if I had the chance. The 4-2-1(more mid power gain) or 4-1(more high end gain) is up to you. As for intake, I would have to say aem. www.nolimitmotorsports.com has very good prices on aem intakes, thats where I got mine. I would get coolair unless you get a lot of rain or snow where u live (i live in ohio, so i got the ram air)
