manifold or headers??

[superseb21]

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 ??

Do you have to worry about emissions?

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.
