Default Rattling noise after braking rx350-2010

Lexus rx350 - 2010

The car makes a rattling noise after braking and decelerating usually from 20 to stand still. Sounds like it’s coming from back right corner of the car.

attached a video of the noise, any tips ?

thanks!

Sounds like the donut gasket in-between the catalytic converter and y-pipe of the exhaust. Could also be a loose exhaust heat shield near that area as well.
