front end rattle when backing up

i have a 2005 double cab limited and the front passenger side rattles when im backing up or slowing down. but if you stop it goes away after about 15 seconds, i've looked everywhere and i cant tell if its the drive shaft, the exhaust or the wheel assembly. if anyone has ideas please let me know

 

Try tightening the exhaust shields.

 

Foreground is the old rusted OEM clamp (rattles). In the backround is an stainless snake clamp from big box. I’ve done this in a few spots.

Just noticed I have a bolt missing on one of my cat converters. No rattles but will be replacing soon with a bolt/nut combo.

Let us know how it goes!
