sounds to me like you've got an exhaust rattle, have you tried getting underneath the car and shaking it to see if it's in place properly?

My 88 Camaro had a similar problem recently. Yes, you should check your exhaust. Especially the catalytic converter. In my case, the heat shield was a little loose and just needed some tightening. Because the cat is closer to the front of the car, this may make the rattle sound like it's coming from the engine.
