Hi Jeff, The ceramic coating would benefit the exhaust as it protects from corrosion however, it also acts as an insulating cover to not only prevent heat escaping into the cowling area but also keeps the exhaust gasses hotter and thus less dense which aids exhaust flow. Better exhaust flow = better engine breathing = more RPM & HP.

So the extra 200 rpm gain I got after having Jet Hot ceramic coat the exhaust and gain in rpm was exact same set up. Same carb, same prop, same plugs. I cant really explain how just cerami coating the exhaust gained 200 rpm. Unless possibly I was not getting a true full throttle prior.
