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.

Josh has a Legacy Sport. Nothing done yet for power just suspension, but we did replace the old exhaust. It has an sti exhaust. Sounds good I would guess it would be plenty sufficent for an upgrade in turbo since it was design to operate the sti. You have to get the exhaust lengthen about 3" iirc, because the front to rear dimension is longer than the Imprezas.
It would be good to upgrade to an engine/ecu that excepts some kind of add on engine management. Josh hasn't done anything to his for power because he'd need a stand alone engine management. Also the engine in these cars is a closed deck model, so it can handle a decent amount of power if you can find a way to manage it.
When Josh wakes up I'll see if he can put some input in on the tread.
