If the 0420 code comes on after awhile it is proof the cat is bad, 40 miles might not be enough for an old cat but if the cat had been new, 40 miles of proper driving style after cold start would have been enough.
It is fairly common for the V6 cat to go bad due to the small amount of oil that is passed through the turbo seals on most of these engines.
Check and see if you have a bluish cloud of smoke from the tail pipe 2-5 sec after start up cold.
