Cervinis Side exhaust hanger broke?

Hey guys the other day I had to change my two rear tires, my car was to low to put on the lift so they used a jack and did each tire individually. The next day I was driving and started hearing loud bangs when I drove over little bumps in the road. I looked under my car and noticed the back left driver side exhaust pipe was loose, not like it was going to fall off, but loose enough to rattle around hitting the frame rail. I have attached a few photos of what i think is the culprit. Do you agree? If so what are a few low-in-cost ways to repair this problem? looks like it needs a weld? how much do you think that can cost? any info is a great help thanks!
