Strange buzz when decelerating - not all the time

I noticed when when downshifting on off ramp that the normal sweat sound of my dual exhaust and intake close to left ear turned louder taking on a buzz quality. I was able to repeat letting off gas after revving fairly high in second.

Only way I can think of describing is it sounds like the intake tube may be leaning on something when decelerating hard casing vibration/buzz.

Of course my mind goes to engine mount going. I know given my reading here that my front motor mount is likely in need of replacement - '99 with 74K.

Heat shields, exhaust coupler is loose, mounts. In that order.

That's when the heat shields are expanded and exhaust is hot and parts expand. If only when hot then I'll say exhaust. Best guess.

Not inside the cabin? Or soft top storage area?

No it sounds like it's from behind. II first thought it sounded like it was coming from intake opening.
