Exhaust Coatings
Discussion
Hi All,
I just wanted to post this pic of my Griff manifold for those who have had thoughts about improving the under bonnet aesthetics.
I didn't want to put the rusty old ones back into a fully restored car so I had them very fine grit blasted by Central Engineering Design Ltd and then asked Camcoat to treat them internally (2 coats of internal ceramic coating (TLHB)) and externally (Cermachrome) to reduce the heat and improve the looks. I think these must look close to original stainless and will stay like this forever.
Both these companies were very pleasant to work with. The bill for cleaning and both Camcoat treatments was sub £1000. This was for both headers and the 2-into-1

Nice,
I have used cam coat in the past and recommend them.
I would be concerned about spending that money on a set of rusty manifolds though. I would worry that they would rust through at some point and your investment would be wasted. That said, I note they were blasted and have had the ceramic coating applied internally.
While expensive, it makes a difference to engine bay, and footwell, temps.

They look great and I've no doubt that they'll look great in your car, but, 1k? Wow, that's kinda scared me a little/a lot as I'm planning on a set of Clive Ford's equal length manifolds and getting them double internal coated....Christ knows what that'll cost!
I was clearly well short with my 5-700 estimate!

Two coats internal was £380 for both manifolds and the 2into1 which I thought pretty good going. (including internal pre coat prep) I then send them out for vapour blasting back to clean SS but vapour blasters dont like surfaces as flaky as this as it wrecks their particulate. Therefore they had to be fine blasted ( a very matt finish and resent to Camcoat for the external coating to bring them back closer to original. If I had had Camcoat do both in and out at the same time it might have been £300 cheaper so don't despair. I just went at it arse about face. I'm posting so no one else doesI was clearly well short with my 5-700 estimate!

Hi Dunc,I have used cam coat in the past and recommend them.

The cleaning removed all the rust (more like accumulated tarnishing) so I'm pretty confident that this will last and either way if it can get that engine bay temp down I'm more than happy.
I have very painful memories of being in crawling traffic on the M3 in high summer with the roof down and dreading each time the fans came on to blow oven temp air out of the wheel arches and over the doors onto me. Betty Swallocks......Poached in my own sweat for 2 hours. Lovely. Must have lost a couple of stone.

Looks good, myself due to cost and manifolds being 20 years old bit the bullet went for Clive ford equal length 
very happy ?? 
A thing of mad beauty! very happy ?? But they will eventually look like my old ones
Camcoat doesn't rust or tarnish. I recon such state of the art pipes need a coat. Camcoat do a very high temp clear coat for new SS. I'd be tempted if I was buying new...I'm more than happy if my cf manifolds took on the tarnish golden/Brow look as I personally think it suits, but I having the internal coatings may well prevent them from fully hearing up enough.... 
Im looking to have the internal pipes done as to keep as much heat in them as possible as it may well be necessary to fit a cat further down the system if MOTS/emissions start to become an issue - you need to get cat up to temp and apparently the single pipes cool down quicker that the conventional set up .

Hi Matthew, have yours discoloured yet?
Hi Adrian, yes i never kept on top of the polishing so they have tarnished. They still looked good on the car as I did give the tops a quick polish now and then. When I took them off the car the places where you cannot reach with Autosol are very dull. 
also pre cat. Proper Tvr. In mine opinion could be opening a new debate don't have pennies for new one parents still here. ( joking) Camcoat do say that if there is any tarnishing a rub with 0000 grade wire wool does the trick.
I suppose nearly anything, metal or coating, if at a constant high temp will have a degree of surface oxidization over time. Not necessarily degrading the coating but collecting on its surface where it meets the atmosphere.
