The best way I can describe the noise is it's like when you accidentally lug the engine from letting the RPMs drop too low while the car is in gear. Except when I hear my BRZ rattle like that, the BRZ is in neutral and the RPMs don't seem to be dropping low at all (staying around 600rpm). Furthermore, neither the car or shift knob rattles when the noise happens.

I've experienced the same thing when coasting in neutral. I don't have a solution, nor am I a mechanic, but I have wondered if the car idles lower than it should. I've seen the rpms drop as low as 400 and then sputter back up to a decent idle of 6-700. I'd be curious to hear what folks with more car experience have to say.
