At cruise speeds the exhaust gas as it leaves the head is about 1,300 degrees F. By the time it makes it way back to the muffler it's still in the 500 to 600 degree range. So yes, stuff glows.

The sound blocking plate takes all the heat from the header causing it to blow, did you get a muffler with a cat too? It'll glow brighter... itll start blueing soon, dont worry
