Its a process for ceramic coating exhaust headers inside and out, I can only find dealers in the USA, anyone seen it advertised in the UK.
This USA Zetec MGB manifold is treated and looks pretty cool:

I think there is a UK company called camcoat.
There is always the do-it-yourself option
Cermachrome
I used this on the Radical's exhaust and has held up well (apart from where TTS ground some off to weld in a bung for a Lambda sensor)...

I think TimC had the same thing done to his vortX - check out his blog for details on it....

My sidepipes for my Cobra came from the 'states. The Jet Hot coating is amazing. they are cool enough to touch so quickly and the coating seems to keep it's appearance (2+ yrs on)
Zircotec advertise in PPC mag, they coated an exhaust manifold for a Westy in an article. It seemed very positive,
the article that is.
