It's the exhaust. Get new exhaust hangers and if that doesn't do it you'll need to remove the stud from the inside rear seat mount and replace it with a shorter bolt.

Yeah sounds like the exhaust, could be like the issue I had with mine. It was rattling against the hangers and frame. It took me 3 weeks to figure it out. Also, you might not be able to find it by hand, I couldn't apply enough pressure to my muffler to get it to make the noise. Try getting it on a lift and starting it up, see if you can follow the sound and figure it out.

Check your heat shield. Those rattle when they get loose and you will hear them when decelerating
