I will say this, with his coating, inside and out, I can put my hand on the headers just a few minutes after a 30 minute race. Before I coated them....forget about it...could take 1/2 hour or more.

Huh? I'd be interested to know more about any objections that 'vendors' (or whoever) might have objections to coating... 
I installed LS7 exhaust manifolds on my LS2... had the Jet-Hot Extreme Sterling done before install... they look super and there can be no question that they reduce under-hood temps.

Hey, that's cool, good price. Here's a dumb question, do you have these already Jet-Hot coated? I'm also thinking about LG's, too, do you also carry these Jet-Hot coated?
We prefer not to use exhaust coatings on headers.....
I never liked em'.

FWIW, I'm on my 5th turbo Buick, 2nd vette, & 1st '09 Cad CTS-V, and from the knowledge that I have gained over the years on this subject and from talking to peeps, I would never again install uncoated headers or downpipes.
Some years back there were some rumors going around that ceramic coating would or could crack the stainless headers / downpipes. I have personally never seen proof of this and doubt it's authenticity in anything other than an isolated incident.
Header wrapping will hold down the heat, but at the risk / loss of appearance and the safety factor of wrap getting oily and being a fire hazard. I would never use wrap even on a race car. Just not as professional looking as I would like to be considered. Stretches in time too.
Not a dig here against any of the fine supporting vendors / suppliers / shops on this and other sites but I think that shops don't like coating as it is an outside process that they can't control, extra time involved, and possibility of any errors such as shipping delaying the shipping time to customer.
Just my curiosity, but does Kooks, American Racing, and most other shops of this nature charge an additional outside source fee.
Regardless, I was quoted $300 a while back for Kooks with the headers coated, don't know if that is inside and outside and whether that is the Sterling or not.
Very sorry for the long post. HTH
