It's really hard to see in that picture, but there was a hanger right at the end of that pipe. It was still, there was absolutely no movement. Your right though, it could have been the installation. Either way though, I'm gonna try and get a new muffler. I'll probably throw a hanger or some wire on the end of the muffler for safe measure.
On the upside, it actually sounds better coming straight off the muffler lol
