Please don't just gut your cat, it will let a lot more NOx emissions out your tailpipe.

Take your converter off, soak it in a mild citric acid solution for 6-8 hours, then flush it with water at moderate pressure (not from a pressure washer, basically), remount, and if it was plugged with soot, it's good as new.
