2016 Ford Mustang GT strange underbody noise?

There's a noise from underbody I can't diagnose. It doesn't matter if the car s cold or warmed up, it's there no matter when you start it.

Please see following videos;

And to what following videos are you referring to?

The noise still there or did it disappear with your videos?

The first thing i would check is the exhaust pipes and make sure all of the brackets that hold it are good.
