It's a low frequency drone/hum so it sounds like it comes from everywhere. I think it's mostly the rear mufflers and the hatch, but it could potentially be the resonators and the X pipe right under the driveshaft tunnel.

I am planning on some dynamat, closed cell foam, and then some mass loaded vinyl to cut out on the noise from the hatch area and will see if that helps.
