I removed the exhaust headers from my 2016 Chief Dark Horse after I had removed the OEM mufflers. I took my recently purchased Vance and Hines turndowns and my exhaust pipes to a ceramic coating shop in Raleigh, NC. I recollect that it cost around $350 to get the entire kit and kaboodle ceramic coated. Initially, he said he'd likely have to remove my heat shields to properly clean and coat them. It turned out he did not have to, so my entire exhaust system is now ceramic coated. I reinstalled the system myself. After a couple years, it is beginning to show some age. The ceramic coating throws off heat better than chrome, which results in the pipes cooling down much faster than the original chrome. Good luck with yours.
