new forum member. not yet a wrx owner, but that may be changing soon. i'm on the boards primarily to get info for now.
one question. the vehicle i may be getting is bone stock. the engine is currently out for a mechanical issue and when it goes back in, it will have the invidia up-pipe, as i read that was the very first mod to do. i was looking into a downpipe too, but i guess you need to tune for that? i have 2 of the 4 cats removed on my expedition, and the only reason i need a tune related to that is to keep the cel off. what's different on these? keep in mind, i'm completely oblivious here....i am a die hard ford man, and have worked for ford for over 10 years, so if this happens, i'm at your mercy! thanks in advance.
