Odd rattling sound around 2K RPM

Hello all, just trying to find out my strang rattling sound. Its only when im driving and the rpms are at around 2k rpms. It almost sounds like a rock rattling inside a pop can. Nothing seems loose, and its not suspension related cause it doesnt happen over bumps or anything. I would try to get a video but it was really hard to get the sound through the phone. It seems like its somewhere around the center of the jeep, underneath. Any input would be greatly appreciated!

Its a 2008 unlimited 3.8 sahara with 51k miles.

Sounds like a heat shield is loose somewhere.

It sounds like the heat shield on the exhaust crossover in front of the transmission crossmember.

Put some hose clamps at the weld connections to verify.
