Anyone know much about ceramic coating headers?

TTI warns you of this when you buy their headers.

I screwed mine up by doing this to mine when they were new, wish I would have tuned my 440 with old headers first. I did not have enough timing when I broke in my cam and fried the coating right by the flanges. My bad and am living with it. I actually burnt a hole/ crack in one of my headers, took it off and welded it back up from the cam break in.

Other than that I don't have anything else to add. Good luck Stu.

Really.....??? I can understand if the headers were glowing red from way over richened settings, but if that was true why didnt the original TTI coating fall off ater 10 years of use.

just had mine done by the same people, (i'm assuming).

i know my engine isn't too lean, so we'll see what happens. mine are silver though, not the second coating of black.

Yes let me know Mick how they hold up.

The headers wouldn't turn red from a rich condition. That is caused by running lean.

I just had my TTI headers re-ceramic coated by local company who makes and sells headers.

The issue is that the ceramic coating is falling off the upper tubes where they meet the heads.

You can just rub your hands across the tubes and it flakes off.

I paid extra to have them first shoot in silver and then in black as they required for dong the black finish.

I just called them and the owner said it's due to my carburetor being getting far to rich and running to hot.

I disagreed as #1 the header never did that with the factory coating and I just had it checked by the guy who tuned the carburetor last time and his meter showed it was not too rich running.


I told them this but they still insist the header tubes are getting too hot and it's not their problem.

So I think it is their fault somehow for maybe not putting the base coat of silver on first.

Anyone have an experiences with this sort of thing? Just wanted to see if their explanation is truthful?

If you post some pics I can likely tell you what’s going on for sure. Is both the black and silver crumbling??? Based on your guys initial description it sounds like he’s a bit mixed up. As someone already pointed out, damage to that area of the primary is from a lean condition, NOT a rich one. I’m not sure what kind of Frankenstein process he’s doing, as most “non bright “ ceramics should be good for close to 2000F and it’s nearly impossible to hurt them. That being said, most failures for “Bright Ceramics” are caused from either a “too rich” or “too lean” condition. Both are equally BAD…. Too lean will cause failures between the head and mid primary. Too rich is from mid primary to the collector.

It appears that your coater never gave you any direction as many don’t, but special care is required for ALL bright ceramics. Most important on that list is that you NEVER break in, tune, or dyno an engine with bright ceramic headers. Doing so will put them in the dangerous rich / lean area discussed earlier as you can see below....

Can damage to the coatings be caused just during idling? How long does it take to do permanent damage if too rich/lean?

I had mine ceramic coated at a place in Belmont. I forgot the name but they cost me $240. If you want I can try to find they name and give them a call for you. 7 years later they still look great.

Hey Ricky that is ACC Plus shop and i would have gone there but the shop i used was only a couple of blocks away so the convience factory was what i choose (Sandersons).

So what i came up with after talking to the gal there was when i pull they engine to do the rebuild (hopefully at the end of the year) they will recoat them at no charge. Guess that's about the best i could expect them to offer anyway.

You can damage bright headers in less than a minute if fuel or timing are off far enough.....

That will actually burn it turning it darker & making it feel like 320 grit sandpaper
The peeling on the flange if not discolored is poor prep

I think the reason is the company did not first do the sliver coat as they promised. If you wipe away the top coating of black cermaic you can see the bare metal below.

I had them do the rest of the exhaust system in the same black ceramic coating and it is holding up perfectly. Only the areas close to the heads are falling off.
