Technology / Re: Should an exhaust pipe be painted black or silver to best radiate heat?

Hi, Everyone.
I know it'll have to be high temp paint.
I'm not after cosmetics here, it's the exhaust. I just want to keep it functional for years, it's quite a rare little and parts are becoming harder to source.
I also don't want the pipes to emit any more heat than the currently do, I'm just after protecting it from moisture, and then rust.
So if I painted them in silver paint, it'd be better than black paint which would turn them into "radiators"? As the pipes are silver on the outside anyway, I guess that's the best option?
The cat is right up at the manifold, so that's not an issue.![Smiley :)](https://www.thenakedscientists.com/forum/Smileys/default/smiley.gif)
