I would check if the shields are not loose or something stuck in between the shield and the exaust pipe itself. Very common here in New Zealand as the stone chips on the roads keep flying!
Be careful of the heat off the pipe as you can easily burn yourself.
Ideally it would be a good idea to put the car on a pit or hoist. If not try to put the car on wooden blocks so that you can get easy access underneath. Good luck and keep me updated.
