My headers were coated by Jet-Hot.

 

Honestly, I'm not too pleased with them at all. Luckily, they have a 10 year warranty, so whenever I pull the motor, I'll send the headers back in.

 

The problems:

- They car in a "sterling finish" which almost looked chrome....they looked freaking AWSOME. That lasted about a week. :rolleyes: Not they are gray.

 

- RUST. The whole idea of coated is to prevent rust and keep engine bay temps down. I have long tube headers, so the collectors go under the car. All along the collectors, they are full of surface rust. They started rusting after a month. There is even a tiny bit of rust forming around where the primaries meet the header flange. The "Hooker Super Comp" tag also has a little rust on it.

 

Overall, I don't know if I can really suggest them or not. I'd like to see how my headers are after they get re-coated, to see if they last this time. I sure hope they do!!

The best ceramic coating materials in terms of resisting heat are satin black in color. (It has nothing to do with the color, but the chemical composition) All of the coating places are generally using the same sets of chemicals, btw.

 

I'm probably going to get some over the winter and see how it works. If I can find a link to the stuff I was looking at, I'll post it.

Mark, keep me updated please. There is a certain 4 door V6 that will need it's headers coated this winter and requires the same degree coating that you are looking into. (Damn M90!) smile.gif:cool:
