yea i feel bad for some of those non PIs. My buddy has one with some mods. basically catback, xpipe, intake and chip. went from a roll one time lol i waited till he got on it then i find out he was in it the whole time with me pacing behind him in second then once his exhaust got louder i hit it and zipped by lol. when we stopped to eat lunch is when he told me he was in it the whole time with me pacing him.
Swap a p.i. intake on, $100 for the intake, $100 for the other parts, and $whatever for the labor, and you'll actually be able to "climb the rpms", as opposed to hitting a brick wall power-wise, causing you to shift early and be way the hell out of your power band. Or just get a blower
