civic addict has the right answers for you..
I agree the AEM CAI would work for te intake. Good sound and performance from it along w/ being ok to pass inspection.
As for exhaust it treally depends on sound and how much you have to spend. I would also recommend DC Sports,Brullen,Greddy and HKS..
there are also othere to get but show around and find a good price for the mods you want...
Hoep this helps a little..
