80k i would deff go over the tune up stuff but like you said you are replacing the plugs. and like it was already said, the cat conv. is supposed to heat up to burn off as much of the emissions as possible. naturally the rest of the exhaust will be cooler. a muffler, by principle, is restrictive so it will be hotter than the tail pipes.
