Ceramic or other header coating

I use Calico Coating, in Denver, NC....which is close to Hickory. They did the TTI headers for a Challenger I had, and they never even offered to discolor or flake. They blast them inside and out, and do a high heat thermal barrier on the inside. They will do whatever you want on the outside. They charged $225 to do them, but that was about 10 years ago and the price may have gone up some.
