TTI vs Dougs

Hell, I don't even have a problem with hi heat 2000# paint staying on mine , the thermal coating is tougher than paint.
Look again , all the pro run it ! " Are they all wrong ? "
The only reason for it flaking off or burning off would be a piss/poor job putting it on to start with.

I have yet to see a coating that will last on exhaust... Especially on daily drivers...
