I just bought a 2006 WRX limited. It has a stainless catback, which the muffler was stolen at the dealer the day before I picked it up. So, the dealer is replacing with with a similar stainless axle back. Other than that its stock. Plans are to lower it and put wider rims and tires (255s or wider if I can get them to fit) on it and leave the powerplant alone for the moment.
And where I came from
