well i plan to do just about everything with my car. i want to autocross it, i want to take it to a track-day every once in a while. definatly want to street race it, i can't stand honda boys thinking they have more than me when they get smoked every day. plus american cars make a good diet.
so basically the header will be for all purpose, i am trying to build the up my car safely, but enough to get noticable power increases.
