More than likely it's a heat shield somewhere. That 2000 rpm range has the perfect resonance for that heat shield to vibrate like a mofo.

I have recently started getting a similar vibration sound around the same RPM's .... Figure this is what it is as well just have not gotten under to have a look.

Had a similar issue a while back - check the section of your exhaust where it crosses over from passenger to driver side. There is a crossmember there that gets bent upwards fairly easily and may contact the exhaust when the system starts vibrating at the right frequency/amplitude (hence the association with a particular RPM).
