Intermittent buzzing type noise as I drive over uneven roads

Anyone getting an intermittent buzzing type noise as they drive over uneven ground. 2005 SXT 5 speed. New to me I'm thinking maybe a crack in exhaust as it kind of resonates or buzzes.

Depending on where you hear the noise from, yes it could be something with the exhaust. Just that lack of location of it makes it hard to offer more specific advice. Could be a loose clamp/hanger or even a heat shield. Also check the upper and lower front motor mounts for torn rubber inserts. excessive movement from bad mounts will cause exhaust buzzing noises from excess engine rock.

My best guess is the heat shield for the exhaust tunnel has dropped, or is about to drop onto the exhaust pipe. the aluminum rots away around the fasteners, and the shield falls. If the fasteners will come loose, you can get some fender washers, and re attach the heat shield.
