Would actually recommend you start with suspension and wheels if you haven't already. When I think performance my mind goes straight to tires and suspension, to start. Then adding CAI, exhaust, maybe a bigger fuel pump, bigger injectors, forced induction if you want it. Then after the serious power stuff add the supporting mods, upgrade cooling, brakes. Then like the endgame would be to gut the car and put in a roll cage if you're going to take it to the track seriously. Ofc you could go any way you want to but this is how i'd start my build.
