hi there was looking for a little more h.p. for the hemi... was thinking of headers and dual exhaust and say something like a chip or programer, or a cam. what have you done with what results. what about these turbo intake things from tonado??

 

I've read anywhere from 10-20 HP from headers. Duals don't seem to provide much benefit, yet. We need a controller that allows for increased air flow through the engine. No programmers yet for an 04. Superchips has one for the 03 though.
