hey guys. A stock 03 wrx was handed down to me a year ago. Now its got about 112k miles. Im looking for it to last me a long time but i want to have some fun in it too before it gets too old if you know what i mean. What I'm looking for is to increase hp but not at the expense of my mpgs (~23.5). I want powerful sound, but not shake houses when i drive buy.
A lot of my friends are telling me the first step is an intake and exhaust system. One of my cats is busted so i guess this is the time to do my first mod. Not sure which cat is is though (i think theres 3?). Also I'm looking to do the work myself. Can I do this exhaust work if i buy rhino ramps?
