mike! ask anyone here, aluminum does not rust! if yours rusted, then it wasnt aluminum. like i said it will corrode and only corrode.
also back the 2.5 thing. you know im not trying to get 2.5 just to brag to 12 year olds or be cool like a corvette or try to be something im not.
its just, with that 2.5 headers and 2.5 cat back exhaust it just seemed so much more reasonable to have. in fact i forget who it was exactly (he's on this board), but all he had was "light mods" including a CAI or WAI i forget, and SLP cat back exhaust, once he got headers he dynoed a 27 whp gain. so im pretty possitive it doesnt matter if you have heavy or light mods, headers will benefit no matter what. offcourse with the teamwork of a cat back exhaust.
but yeah i know for a fact you will loose some low end with the bigger the pipe, but what i was trying to say earlier was, the 3.4 has plenty of low end torque, and not enough high end. but yeah
