Im relatively new to this board and the whole mustang world. Yes folks after 5 years as a ricer i took the smart route and got myself a real car. Anyways i put a full exhaust on the stang its in my sig. The guy who installed it said adding headers wasnt really worth the time to put them on. I find that hard to believe. Is this guy talking outta his ass or are they not that big of an improvement?
