It wasn't setting any codes before I tore it down and I had just finish a 10,700 mile road trip in it. Any constructive input would be greatly appriciate. Thank you gentalmen.

None of the above its possible that a piece of substrate broke off the honeycomb and melted into place. Impacts cause these to break apart before they ultimately fail. when they fail they start blowing chunks and the honeycomb tends to mold into a large ball of material. You will hear it as it sounds like a chock full of nuts under the car. This is a reason why a lot of us have gone to headers and Hi flow cats. Only other option is to find a NOS cat and exhaust manifold or hang a used one.
