That makes sense. Lol Let me know what you find. I think it has to do with either a loose heat shield or it could be the catalytic converter itself. I have seen them come loose internally and the guts of it rattle.
If you don't hear the noise when checking, have a helper basically load the engine in gear with his foot on the brake so it can't move to see if you can tell better where the sound comes from. Just don't stand in front of the car. Lol
Let me know what you find.
