Ceramic coated manifold?

[BahnStormer]

As mentioned by @Nvy  on the sale thread (HERE), is this recommended? And if so, are there any recommended places in the UK to get it done?

Thanks!

Depending where you are in the country there's Ravenblast cleaning out Derbyshire way that are currently doing a lot of ceramic work. Can't speak for long term but they have a good reputation in the community for their work.

On paper it should keep some more heat in the manifold and working the same way like heat wrap. It will not harm anything at best.

A friend had it done on his race car. You could touch the manifold without burning yourself after a heavy ragging on track!

Done here if I remember correctly.

I have a v-twin motorbike & got the "stainless" separate headers & collector box done by Camcote some years ago. The main reason was for cosmetics, with the bonus that it should improve the efficiency.
I wouldn't be touching the pipes though.....the above claim sounds extraordinary!

Knew you'd be along sooner or later, tried to "tag" you but couldn't remember either of your two's user names.

Any idea if he just had the exhaust coating product or "thermal barrier"?

Since they do full exhausts, it sounds like it might be worth waiting until the entire exhaust system is ready to be done?

It was a coating, in white.

I know its pretty anecdotal, but I was with him after he had a new engine in, he took it for a few laps around castle coombe, it wasn't running right. When he bought it in, he popped the bonnet, and went to work on it. I watched him check the exhaust manifold for heat (As he was working next to it) and then rest his hand on it. I touched it, I didn't burn my hand off!
I remember being quite suprised.

If I ever turbo, I'd like to get all relevant engine bay bits coated, but I imagine it's expensive!
There must be downsides too.
I know his manifold cracked, but I'm not sure whether it was related.

any chance of asking if he knows why? or what what manifold that was?!?

People say that wrapping the mani can lead to cracking as well. So, same concept. I don't know if there's any truth to it but I don't think I've ever seen a wrapped mani on a race car.

I asked about the crack, he said it was probably a defect on the manifold (An mitsi evo iv aftermarket one).
He generally praised the ceramic coating, as it really worked well.

I think it's got something to do with if the coating isn't even.... Pretty hard thing to get right... But basically thinner bits of coating lead to differences in the expansion and contraction with heat and this this can cause cracking...

I think you'll find wrapped manifolds on most racing cars, unless they're of the expensive sort, in which case they are made of inconel and very special.  Ceramic coating is also common and found on many racing cars.  As for anecdotal evidence of heat coating/wrapping causing cracking, it won't happen to a well-made manifold made out of good materials.  (well,  not often.  Even F1 manifolds crack occasionally.)
