You might check with List Member Robert Lilley. He built a "Lilley"
engine .... internal parts coated with ceramic material amond gother
things.... and as I recall he installed  a new exhaust system which
included ceramic coating and then wrapping the pipes with insulating
tape. His goal was to increase power, performance, and life of the
engine and systems, and heat control was a big issue. As I understand
it, the effect of the ceramic coating combined with the insulating tape
was spectacular.
