I have a 2003 mustang gt with ark cat-bac exhaust and a mac pro-chamber
(not off road has catalytic converter) and stock manifolds! I wanted to know if it is a good option to put ford racing headers on it ??
If you dont look into midlength or LTs. Ford Racing Headers are shorties.
Any headers are a pain to put on so you might as well make the most power you can with them. I put on JBA LTs and they made good power and made the car sound much better too. I kept my magnaflow O/R X pipe also and just modified it to fit the headers.
