if you did a drivetrain swap with an STI, that means tranny reduction gear and the Center Diff ? (Plus DCCD ) ?
or just the Tranny ?
and btw, yes the stock BOV on the sti is loud enough for people to hear at least 50 yards away. if you are not going through the stock subaru silecner. I've been told you can do a simple (20 minute) mod so that the stock BOV - escapes directly to the atomosphere, instead of back into your air intake system. and that is suppost to really increase the noise from it. i think i like the noise level that i'm at though ...
