We recommend to all, buy your headers "uncoated" and send them to a coating company. We use Thermal Tech in Hopewell, Virginia. Not only are they fairly close (about 60 miles away), they are absolutely the best we've ever seen. After 5 years of circle track racing, the headers still look great, even the dirt track guys'.
Jet Hot and Swain are the other two we've seen anywhere near the level of quality.
