Yep.

Sure do.



I'd be more comfortable knowing the direction you're going, first.

For example, my own car has a complete SMSP system from header all the way back. The header by itself usually sells for $1200.

However, if you're only after mild, economical modifications for a daily driver, then it might be dumb for you not to go the OEM JDM 4-1 header route, which is a hell of a lot cheaper and might do all that you want.

What is it you are trying to accomplish? Whither goest thou?

Are you sure you don't want to get to know your ITR motor a little better, first, before you spend a lot of money you might regret later?

Perhaps you want to think about driving it enough first to know what it is you don't like, if anything at all. There are certainly thousands of ITR drivers, including many who go to the track every season, who feel no need to modify at all.
