Now that I have done both I see no difference for the performance angle or believe me if one company had the greatest headers everyone would have them. The ceramic coating has nothing to do with the headers performance it’s all about keeping the heat down. Everyone has a choice and can pick which ever one they want, I am just offering my recent experience in two Gen 6 builds. If you just want to buy the most expensive headers then Kooks and American Race Headers are the ones for you.

the only thing a kooks or ar header has over anything else is "made in america". actual fitment & performance are identical.
