Hey everyone, I should be buying an 05 STi in a week or two. I'm overseas in the desert right now, so hopefully I'll be back in a week or two. Not new to the whole forum thing, so I did try searching.
I don't plan on doing too much in the way of mods, except for probably a turbo back exhaust and maybe something along the lines of accessport.
Now to my nOOb questions. I was thinking of getting a perrin downpipe and perrin catback exhaust. But what kind of power gains would I most likely see? And if I go stage 2, what gains would that yeild?
