I've searched but can't seem to come up with anything.
At highway speeds and mid- to high rpms (~3k), with very light throttle there is a loud rattling noise. It isn't at a specific rpm so I don't think it is a harmonic rattle of a heat shield or exhaust clamp.
A lift off the throttle or adding more pedal makes the noise go away.
Before I throw some parts at it, does this sound like a failing/failed EGR? My OBD-I truck isn't throwing any codes.
