I would suspect at this point there is an engine performance problem that is the root cause of the catalytic converter failure.

have you checked for vacuum leaks? if not that would be first on the list. has the engine been using more then it should of oil? was the old CAT very oily?_x000D_

a common problem with 2nd gen dodge rams with either of the 2 V8 engines is the lower intake plenum pan gasket falling apart. this will cause a vacuum leak, misfires, pinging under load and spark knock, overheating catalytic converters and bad mpgs (very
