Also, I don't know what the real term is for the part; I'm just referring to the rubber piece that goes around the exhaust hanger and is then screwed to something under the body of the car. In the below picture it's the visible hanger on the left.

I didn't notice the issue until I was in the process of removing the muffler-only section. It turns out the rubber spacer rotated and the hanger was rubbing against the metal portion of the bracket that held the rubber in place. That explained the rattling at high RPM.
