what causes hot spot or color distoration on mufflers?

Have a '97 2.5L. Runs fine, idles fine, starts fine,new distributor, tune-up about 7K miles ago, no check engine lights.

The tech at a muffler shop said my aftermarket muffler show abnormal signs. He said there were hot spots or color distortions from excessive heat. The hot spot is on the end of the muffler towards the back of the Jeep. He said it might be misfiring from a bad injector leaking. I never remembered any misfires. I assumed the hot spot or color distortion was from the super hot exhaust gas from the cat converter? The cat heats up to 1200-1300 degrees right? Plus my muffler is welded about 14"-16" from the cat converter, could that be too close?

Is it possible the metal on the cheap aftermarket muffler is thin and shows heat more after it comes out of the cat converter?

Could the cat converter be too hot and bad?
