Exhaust so hot it melted all the hangers ??

'88 560sl
Installed new copper core spark plugs yesterday because I was unhappy with platinum. Drove 25 miles with no problems, parked for 8 hours. Then she started fine, drove for about 5 miles, Engine lost power dramaticly and was barely running then the muffler hit the ground.

The tail pipe and rear muffler were near white hot and changed color from the heat. All the rubber hanger had melted away.

Temporarily hung the muffler with wire to get it off the road. Noticed that the pipes were hot enough in just 4 minutes that the welds of the muffler were glowing red.

Suspect bad catalytic converter and plan to pull the oxy sensor.

Any opinions??
