Well after some more research, I think I'll be going with the AEM CAI, the Cobb Access Port, and the Cobb Catback exhaust.
I had one other question, on the topic of downpipes. I really want to build my car up with the eventual goal of having big numbers on hp/tq. I am nowhere near compitent yet but as I learn, I will eventually want to go with forged internals and bigger injectors and a bigger turbo and such. With that in mind, for the downpipe is it reasonable to get a catd downpipe or does it only make sense to get a downpipe w/out a cat in it? How drastically is the performance effected by the cat? And will I be able to pass emissions etc?
I'm just tryin to do all the research I can before I really start working on it.
