Welcome, search function is your friend.

Forget the COBB system. The one map suits all nature of them is a good way to either a) not get the most out of your car, or b) have your engine shit its nappy. Since the maps are based in the US they hold very little relevance here in regards to fuel and atmospheric conditions. Get a custom turbo-back exhaust and a tune to start you off. Search "Verso" and "ecutek", read lots, make a decision. Nothing much to be gained using cold air intake on the MY08-MY13 but if you want annoying intake sounds then go for it. Just make you do that before getting it tuned.

I'm not sure what the stock STi swaybars are like, but swaybars are one of the best bang for buck mods you can do (on a WRX at least).
