They are the originals offering the ceramic coatings for headers. I believe they are one of the few that offer colors other than silver and black.
Nothing magical about doing these coatings, seems most places that do powder coating are doing the high temp coatings now.
I stopped by the shop in my town that does all the coatings for another shop near by that builds custom headers and he gave me the grand tour. First step whether they are new or used is to degrease them. They then get bead blasted to rough up the surface and remove rust. They then go go through the electrostatic application (same as poweder coating) of the coating after which they are baked in an oven. The silver coating comes out quite dull looking and these are tumbled in a drum with media to burnish the surface and create the shiny silver look. The black coating doesn't get this. I was also told that the black actually has a higher temperature rating.
Unless you live near Jet-Hot and can drop the parts off and pick them up I would look for someone local to avoid the shipping charges.
