It won't flake if it is done well. But the temperature cut isn't that great imho. Now if you have it thermal coated by HPC with their extreme coating it will easily cut heat in half. I would do the manifold, exhaust housing, and downpipe. It is not cheap. Very expensive actually.
But, once after going for a high-boost spin in my friend's celica all-trac, he demonstrated the heat barrier capabilities by wiping his barely wet finger across the manifold runner when we got back to the shop. It was remarkable to see him pull his finger away without a burn.
A good ceramic coating will last a long time, and look great. If it is done poorly, expect it to last like spray paint.
