Our OT+ has developed an exhaust rattle that we only hear at low RPM when that RPM is held. It does it in all drive modes and is definitely from the rear muffler area. I've inspected and there is nothing loose externally. Pretty easy fix but just curious if anyone else's is doing this?

This is still pretty bad on ours. Considering a catback or removing rear muffler. It's not so much a rattle but more of a buzz or harmonic resonance at low rpm. Goes away when you get up in the rpm range. Maybe something inside the rear muffler maybe. Anyone else have this?
