Hi Temperature exhaust coatings
Just had my headers fitted on my car and had them done in a high temp coating by jethot (www.jet-hot.com). They can be done in many colours but I had mine done in bright silver. technically they are supposed to keep the temp in the gas flow, allowing faster travel hence more power. Honestly, I got it because the look so smikko.
Now, can this same stuff be done on aircraft exhaust systems, leagally?
In raw terms , how hot is the gas on a naturaly aspirated engine at its hottest. the coatings can stand up to 1700 def F.

I don't know if it'd be legal on an aeroplane, but I know it'd be a good idea. It keeps the under-bonnet temps down and as you say if done properly it'll increase power a little.
FWIW, in Australia it's extractors, the foreign term is headers.

Please don't do it unless it's TSO'd. I can promise you that it will change the balance of heat radiated vs. exhaust outlet temperature, and that may NOT be in a safe direction. If you have a carby, you may mess up your carb anti ice system (which I think is required to produce a 50 degree temp change in the inlet air) or worse, the radiated heat may fry some pipework or wiring.
I did something similar to a motorcycle exhaust once (in a tasteful matt black) and had to hastily remove it because the extra radiated heat was frying my leg.
