I am currently in Iraq but have very few days left. I have been buying performance and dress up parts like crazy while I have been over here. So far I got a hypertech power programmer 3, K&N cold air intake, plugs and wires ( I think it still had the original plugs and wires) just little stuff for to dress it up thinking about a cowl hood and headers but no sure if headers are worth the money any insight on that question? headers being worth the money?
