I get this metal chattering sound only after the car warms up and going 45- or so. At first I thought it could be the shield around the catalytic converter but
also wondering about the heat shields in the engine bay close to the exhaust
manifolds. Anyone experience anything like this?

like you said, the only thing that i can think of is the heat shield.

oh another thing, in my acura, little rocks got in my heat shield causing to rattle also.

good luck

yep, most likely heat shield. asked dealer about it and they cut the loose parts off. no more rattle after that.

It was the heat shield. I was a wimp and didn't rip it off but bended it so it
wouldn't touch anything.
