Yea, listen to wrxisthebest. I would just look for an AP and do it in stages. Are there any mods done to the car already?

On a side note looking to pick up an upgrade under 300 if anyone has an idea to throw out.

well fortunately the downpipe was just installed this last saturday so it's been caught early enough. Looks like the AP is the next item to pick up
