I have an automatic zx3 and I want to get the focus sport race header while it is on sale. What all do I need? Do I need O2 cheaters? I have a diablo chip already in, does it need to be rebured because of the header? How much and where can I get O2 cheaters? Do I just need 1? What kinds of gains do you think that I would see with the race header? I have thermal exhaust, intake, udp, throtle body, diablo chip. Thanks for your help.
Mike
