I know this isn't exactly in your area but Performance Coatings in Jonesboro, GA did some pipes for a Fatboy that belongs to a coworker of mine.
They ceramic coated them black & the finish has lasted very well. No turning colors or peeling .
their web site is
www.headercoatings.com or their phone is 770-478-2775.
I have no affiliation with them other than they did a set of headers for my truck less than a week ago.
