Tough call - I have stainless exhaust on my Harley that is ceramic coated inside and it is as bright today as the day I put it on. The ceramic coating inside has kept the stainless from turning gold, as sometimes happens with stainless steel. Once it turns, it's impossible to polish out.


I just got some ceramic coated headers from Hooker and they look pretty good - will keep you all posted as to how they wear.
