litterally just a few hours ago bought a 99 626 LX 4cyl. I was not immediatly drawn to it but thats what i got and have already found all the potential it has. I have read other posts about "true" CAI's and havent really learned much from them. Im not at all a mazda guy, more toyota, but i would love to make this car something to behold. what i was wondering is where can i buy a "true" CAI without having to fabricate anything or atleast fabricate very little and if i have to relocate the battery how would i do so? Also what is a catback exhaust system relative to others and where can i get a good exhaust system? I also do not know what a Header does so if somebody could fill me in on that as well...

Thanx much
