I'm still a rookie on my knowledge of the STi. I was wondering what is the best technique to launch my '06 STi. I don't have any major mods done to it, just a spt exhaust and a greedy bov. Also, what kind of engine mods do any of you recommend to me? i'd like to be around the 350-400hp range. Would a downpipe benefit me? hope to hear from your responses soon! thanks!
