No, it's a thermal insulator coating - supposed to be good for 500 degrees but I'm right at that threshold. Plus, I may not have been thorough enough with my surface prep before applying it. The mufflers with ceramic coating seem to act like a heat sink. Long after my headers and collector are cooling off the muffler temperatures stay up there. Doing it again, I think I wouldn't ceramic coat them.
