Wussup wussup! ok guys seeing as how im not a mechanic or anything, i had a question. Would it hurt if my two modds were a cai and rbc intake mani, but with stock Si exhaust, header, etc.
go for it. the main idea is you are just adding more intake.
it shouldnt really effect the exhaust manifold at all. alot of people just replace intake and call it a day and their cars run fine so yeah.
