Hi Jack
I am about to get my headers and pipes done in the next 2 weeks.
The man doing them does not use "jet hot" but another product line. His claim was made to me on the phone while we talked about the product. He also mentions that the 200 degrees was knocked off or a harley drag bike and I think was measured with an IR thermal gun. He also claimed the heat is contained more within the header.

Just like the story about painting headers white vs. black

I agree about your comments on appearances...As for the overheating..who knows? Maybe the ultimate is the wrap

We all know that bare headers will act like heating tubes in a heat exchanger as the air is passed over them, that air will get hotter. Open the hood or close the hood all contributes to contained hotter air
Too bad the comparison you use or had wasn't between painted headers or bare and then ceramic coat.

You may be right about wrap...a simple test is too grab either one....whichever method burns you the worst is likely the least desired for insulative thermal barrier.
