Yeah, the 3.9 ratio is correct. I remember you saying that the 1.8's had a closer ratio or something, and I imagine that they are on par with the 2.2's for durability. I just don't want to run into an electrical or mechanical non-compatibility.
On the exhaust, I just want a stock look on the muffler, maybe I can have the 3" pipe fitted to the muffler by the shop that does it? Aren't the WRX and STi stock mufflers pretty high-flow? I definitely don't want loud.
