Header coatings
Discussion
I had heard the ceramic coating can break away... If so, and you cats downstream of the manifolds, could then damage/ block the cats? That's my worry for an internal coating but this is of interest to me for another project I am working on, so it would b great to get some updates, once you've used the car for a good while!
I have the same finish on my headers and silencers.
Done in 2004 and covered 17K miles.
The finish is still good apart from one section on each side. I have identified that water sprays through a small gap in the inner wheel arch and hits a small section of the pipe. The rapid cooling is most likely why the finish has failed just in this area (about 4 inches).

You need to get out more........... only 17k miles in 9 years - less than 2k a year!
Get it back on the road and continue the enjoyment.

+1 on the internal stuff especially with turbo applications, external is really quite good and lasts a long while.Steve_D said:

Thanks for this - I'll keep an eye out. Done in 2004 and covered 17K miles.

As I won't be running CATS the issue on the internal coating breaking up won't really be a problem but I take the point. Have no intention to turbo the car - would prefer supercharger but that's way down the road when the cars finished and I need more power.
Mine lasted the best part of five years (the black stuff) and is now pretty flaky on the bends of the headers and getting rusty. I have a spare set of manifolds in the loft which I am tempted to get done in Zircotec once I have re-jigged the exhaust to suit the ally heads (also in the loft), add a cross over and a smaller silencer.
Zircotec are also just down the road from me an hence hoping to negotiate a discount face to face..

A number of us had our headers Camcoated a few years back.
I had mine finished in the aluminium (SBC) , thought it was really good and I thought things cooled down much quicker than without the coating.
I liked it so much that as we speak, i'm having my LS headers coated.
Hoping to pick them up at the end of the week.

Ceramic coatings of exhaust systems are awesome! Unfortunately, not all ceramic coatings are the same, nor are the companies that provide them.
I live in the US, and am fortunate to have a very small company that does my coatings. They are very honest and ethical. The owner is a "good-old-boy" who has a small shop, down an alley, with a "Beware of Dog" and a "No Trespassing" sign along the way.
I have my headers and exhaust systems coated inside and out. Over many years, with many cars, I have never had a problem with his coatings! You need to ask around and check out the coating company! I have friends that have them done elsewhere and they are turning to crap in only a few years.
You also need to consider whether you are building a show-car or a functional/race-car. My understanding is that the black coating is the best. Although I don't think it is very pretty, it has the best insulating function and is the most durable for high-heat applications. Ceramacrome is great looking, but has less insulating value, and is not as durable. Personally, for those open applications, such as my Lola Indycar, it is good trade-off, but for enclosed and tight applications,....not so much. Titanium color is simply half-way in between, a mixture of the two. I have one car, a Cobra Daytona Coupe, that has the entire exhaust system coated in white, for obvious aesthetic reasons. I would not consider it to be as durable, but much better durability, and certainly much better insulating, than the old VHT paint.
I have stainless steel exhaust on my Ultima GTR, 383, dry sumpted, etc. My car is currently down in southern California at the Thermal Motorsport track, but when I bring it back to Oregon I plan on having at least the headers and mufflers coated in black. The glue-on heat barrier under the rear canopy gets very HOT! I hate to cover up the stainless steel look with black, but on the other hand it is just like a truly great woman: may not be quite as good lookin', but much better for you in the long run........ Just my opinion.

on pistonheads there is a section called "readers cars" I would very such like to see a thread on your collection. it sounds very good.I live in the US, and am fortunate to have a very small company that does my coatings.
