So slamming the door didn't help but I tapped the cats with a rubber mallet and I'm fairly certain it's the drivers side cat. You can hear similar rattling. I'm going to inspect the flexplate one more time tomorrow to rule that out for sure.
Can anyone identify this horrendous rattling noise?

FYI, the flex plate can be cracked in a circular like pattern surrounding the crank hub bolt area. Nearly impossible to see with the transmission bolted to the engine.
Think that if it was a loose bolt the noise would be a lot louder with a lot more rattle to it. Ran a video a day or so back in which the truck in question had that kind of noise and not only were the converter to flex plate bolts loose but so were the flex plate to the flywheel ones as well. Flex plate was junk; mounting holes totally egged out. Noise wise, it sounded a lot like someone had put a bunch of nuts in a gallon pail and was shaking it quite energetically.
