My EGT on the turbo SVT routinely reached into the 800's Celsius. That is HOT, be things were not melting.

You have to remember that is the gas temp in the center of the stream not the actual metal temp. The metal sinks heat away and so forth and as long as overheating is not present it won't have a problem with it.
