ECU reflash is a definite option considering it ups your boost a bit and is completely reversible.. I'd avoid the MBC to avoid any problems down the road. Little things like a K&N panel filter... catback exhaust.. minor suspension upgrades, won't get you in too much trouble based on the warranty. Anyways, get on some Subaru forums and do some searches, all of these topics have been discussed 100s of times and have great information. Enjoy the ride, just don't go overboard and you'll be fine.
