I've notice the exact same thing (2017 BRZ). But it doesn't make it all the time. I thing it's pretty rare actually.
It seems to come from the back of the car. I tought maybe it's a thing call differential backlash, where you have a little "play" in the differential gears (something normal), and that going from compression to acceleration the gear make that noise. But it could also be from the muffler. Even tough it's a mettalic sound, I feel like it could be some kind of rapid pressure change in the muffler.
