Im doing a full 2 1/4" pipe straight through from the flange after the turbo. I'm still thinking on wether or not to do an RX7 or Legacy top mount where the spacesaver is normally kept.
Anyhow we've free bosted her breifly and she pushes on to 20psi but hold 7 - 10 standard. Thats another thing i'll crank that to like 10 - 12 if i can intercool it otherwise i dont know. i've done the stereo but thats not important :D
