On a seprate note, i've had same tips coated on my X5M for nearly a year with zero issues and 5K miles.. exhaust tips do not generate heat like downpipes..

Like Adris said ceramic coat is best solution but not mandatory..
I was racing a Hellcat when this happened so it was pedal to the metal exhaust temps.....I am back with the oem tips for now..... I may recoat them with a higher temp coating
