How much of a difference do "offroad" headers make over air headers.

How much do the "offroad" (no air/egr) headers actually make for a difference in power if any over ones with air and egr hookups?

I'm pretty sure the only benefit is getting the AIR crap out of the engine bay so it looks better and not a pain to hook up.

I thought it prevents exhaust gases from contaminating fresh incoming air.

well unless they design the primaries and everything different, they're wouldnt be a power gain by just having a set with the hookups and without..

Off Road Headers are called that cause they are not road legal, cause there is no emissions. They are alot easier to hook up, and look alot better in the Engine bay in my opinion.
