I dunno man, usually exhaust rattles are a little higher pitched than that. Doesn't mean it isn't from the exhaust though.
Do you have a stethpscope? Maybe you can put it on the cats and see if you can pinpoint it?
The vid is hard to tell since you can't listen and try to pinpoint where the noise is coming from, but based on the sound alone, i'm not convinced 100% it is exhaust. Doesn't mean it isn't, but i can't tell from my seat here

I would say something, but it has basically already been said.
1.Hard to tell from video
2.Might not be exhaust
You might want to take it outside the garage and out into the open and make a video. There might not be so much echo, and it would be easier for us all to hear it.
In my opinion, I would say its coming from the cats, but it might not be, just like everyone else has said.
If you eventually get tired of it and can't figure out the problem, then here's what I would do. Get someone to cut the cats off for you, and sell them. Then get someone to weld in straight pipe so then you can sell it as an offroad h-pipe. I guarantee SOMEONE will buy it. I don't know where you live, but around here a single cat will go for $84 bucks a piece. The scrap guys pay big money for them.
All that money can be put towards a new pipe or something else.
See if you can get another video in here.

I agree that exhaust rattles are usually higher pitched, but it's hard to tell what it sounds like from the video. My buddy had an idle rattle under his car forever, even after it had been taken apart and put back together a few times for various things. He finally decided to actually find the problem this weekend, and it ended up being one of his o2 sensors falling apart. Just another place to look.
I had a similar problem a little while back. It turns out it was the heat shield thingie on one of the cats that came loose. All I had to do was literally reach under the car and I could pull it out from over the cat. The sound wasnt exactly like the one in the clip. It was slightly faster and higher pitched.
I recently removed my cats after one developed a rattle. I initially thought it was the heat shield but it turned out to be internal. It actually behaved just the opposite of Aaron's. It would be relatively quiet when the car was cold but the warmer the car got, the louder the rattling. The sound from the video clip is very similar though. FYI, this was a Catco h-pipe I had on my '92.
I was gonna say but someone beat me to it sound to me to be your heat shield on the cats. I would check both sides see if its rattling on top and yank the thing off. I have had this happen a ton of times to me and welding the cats back up are just a waste of time its just a basic spot weld and they come loose again soon after. Mine would always rattle the worst when I would sit idling at like a drive thru with building be soo close it would make it sound twice as bad.
