hello all i have an 03 civic ex that is bone stock. i'm looking to upgrade and start tuning but have no idea where to start. A friend told me to start with an exhaust. So as to not waste my money on crap; does anybody have any recommendations on where to start and what is best in terms of quality and price? Thanks. note: i am a serious noob who does not know anything about cars. But I love speed. help in anyway!
