Check the heat shields on the underfloor (between the exhaust and the floor pan). These are usually pretty flimsy and can be bent fairly easily if you are not careful. These will create a nasty buzz/rattle.

This was definitely true for me. It gets worse the hotter they are. Mine would rattle at takeoff, at certain RPM's, and then constantly at freeway cruising speeds when it's hot. I took a bottle opener and stuck it between the body and heat shield and started prying it up some, it didn't need much.
