Heat shield on my '00 Ford Focus

My heat shield was loose and my dealer said it should be fine, but then it stormed and driving home I ran over a branch and when I got home I noticed the heat shield was ripped and dragging on the ground. It is pretty torn up and I’m thinking of just taking it off. Am I allowed to take it off? If so how should I go about taking it off?

The heat shield is probably spot welded onto the exhaust system.

If you wiggle it back and forth, at some point the heat sheild will break off.
