I was driving on a dirt road, must have been used with tractors cause it was real bumpy. Came back home and noticed it sounded slightly louder, along with metal banging. Looked under and the tailpipe was broken cleanly right behind the resonator. I'd be sad about this, but it actually sounds better now. I'm assuming it's illegal to drive with no tailpipe, but I hope not. Here's a photo of the resonator: https://i.imgur.com/sivYpjM.jpg I was thinking of replacing the muffler anyway, so I guess this is an option.
