Default Vibration

when I'm cruising about 50 mph and about 1300 to 1400 rpm in my 93, I get a low metallic sounding vibration, if I pickup speed it goes away. Anyone have any ideas, thanks Jim.

My exhaust rattles against my x brace around 2,000 rpm, I found this by driving with the windows down in alleys or parking garages. It takes time but you will find it. Start by tighten your O2 sensors and check you heat shields.
