Ok, so I found a place in the Charlotte area...
DLC, PVD, PECVD, Teflon, Thermal Coatings | Calico Coatings
They come highly recommended and the sheer range of what they coat is staggering. Here's the thing; I'd like to keep my shiny new exhaust shiny, realizing it's 80% plus hidden from view (wheels down anyway). Jet-Hot's higher temp coatings have a crinkle finish, or so I gather. I've yet to get details from Calico but am hoping for a stainless appearance that will handle the heat and not discolor. Anyone have an idea how hot these exhausts get with a moderately heavy foot about town? I've no plans to track my car.
For those that have had parts coated, was it worth the expense in the way of heat reduction? I'm not really worried about the longevity of the system as I'm guessing that as at least 10 yrs.
