I'm working with a stock '01 Legacy L Sedan. I need more power, but don't have the cash to go out and pick up something like an '01 2.5 RS or something like that, so I'm just gonna stick with what I got and make it decent.
I'm investigating Borla headers (part #17183), an Injen cold air intake (part #RD1210P), and a K&N air filter (Part # 332154). Any suggestions for a decent catback exhaust system? I'm looking for something with a nice and deep sound, but not very loud. Any suggestions?
