got an ex and was wondering what would i need. ive seen em sell with only the header itself and sometimes with a downpipe. would i need the downpipe to complete the install? ive alrdy got aem sri on its way, and im about to buy the magnaflow cat in the group buys, and now im just lookin on what to buy and what i need to complete intake/header/cat.

i know NOTHING at all about performance. please dont tell me to get turbo, cuz im not out for speed. im just goin show and sound. thanks for all your help cuz i sure do need it.

peace
