Buddy at school has a 04 WRX not the sti, He said it is stage two, exhaust, intake, lightweight pulleys, slight tune maybe some other **** but I can't remember.
Pulled up to a stop sign together we took off going about 4-5 mph and beat him about by a door length all the way up to 80 where we both shut it down he said I was pulling on him I wasn't watching.
Pretty good for just a gt with a topswap and a crappy tune.
