Ceramic is pretty, somewhat efficient at reducing under-hood heat, and very expensive. IDK how durable. It may cost more than buying a new header every 3 years. Use a light color: silver or white.
Wrap is, 90% of the time (except: actual race cars with tuned exhaust, and turbos), posing. Any light color is filthy after 1 month, and impossible to clean. If you get an oil leak on it, it will smoke and stink for months. It's one of those things you look back on and say "what were you thinking? Did you dry your old shop rags on the engine?".
