I've started installing the baffle and exhaust system. I had the baffles powder coated black and the exhaust was ceramic coated at hpcoatings.com
People have talked about decreased life with ceramic coating because of increased heat inside the exhaust but the guys at hpcoatings haven't seen this. From what I can read this mostly occurs to turbocharged aircraft flying high with minimal cooling. I haven't supported the exhaust yet, that is why it is hanging down. I had to go buy some anti-sieze for the bolts before finishing.
I am hoping for a cooler cowling plus it just looks awesome!!!!
