I just dropped my used and reworked 2" tti`s off at a coating place. He said the coating would take 2000 degrees, gonna be black . The headers were chrome when bought new by a guy in witchita, I unwrapped the wrap he had on them, and repaired some bashed in places, rewrapped them and installed them to make sure of the fit. That was about 6-7 yrs ago, they had started to rust , mostly the chrome looked like. Fingers crossed.
