Your cat would get very hot like that from running rich. It's working extremely hard. It's most likely toast. You said you "cleaned" it?!!? Other than taking a blow torch to it and gently igniting the insides, there's no way to clean it. Was the honey comb intact or is it plugged? Did a bunch of dust fall out of it?
On the firewall there's a fuel line going to the charcoal canister, and then from there to the purge solenoid on your intake manifold. Make sure everything looks right.
How's your fuel pressure? How are your injectors? Any misfires? Check the ignition and cam timing.
Don't replace that cat until you fix the fuel problem.
Also check your muffler. Take it off and make sure there isn't a bunch of rusted metal and dirt falling out of it.
