Exhaust Rattle need quick help!

[CamaroJoe96]

To start, my apologies for posting in the wrong subsection. Second, my apologies that this isn't a 5th gen, but rather an fbody. I just bought my 96 firebird, and the passenger exhaust has a bad rattle to it. I haven't been approved by the fbody forums yet, so I figured you guys would always have my back. Basically, when I push upwards on the tailpipe, theres a lot of play and the exhaust pipe will raise about an inch or 2. In the picture, the circled area seems to be where the issue is, as the piece inside the rubber gromet looking thing is able to move upwards. I'm sure many of you guys have experience with these cars, what do I need to fix it? Thanks guys!
