i have a '03 stock WRX. my cousin told me i should just put and intake on it and a good exhaust and that would be enough. i post on here asking about intakes but they all said the stock one is great. so i am planning on keeping it there. but as for exhaust (up-pipe, down-pipe, and catback) what are some good companies that sell them with a good amount of sound and proformance gained? also keep in mind im on a high schoolers budget so dont go say a Turbo Sx exhaust haha.
Thanks foryour time and help!
