Hood Flutter Investigated and Corrected

Exhaust buzzzzz, could be turbo whine coming through.. is it at the tailpipe?
It's definitely rear driver side area, only at low rpm (not sitting at idle) and more prevalent in Comfort and Eco. Maybe the other settings keep the rpm's a little higher so not as noticeable. Very hard to explain but numerous people riding on back seat have been like "what is that buzzing sound?". It's not license plate or trunk vibration nor is it anything loose in the exhaust. I may just have a shop cut and replace the rear resonator and hope it fixes it. Or, I may just disconnect the rear exhaust section right in front of rear axle and drive it a bit to see if I can isolate the issue to that rear resonator. Wouldn't be the first buzzy resonator.

I had a slightly bent heat shield causing a buzz around the rear axle. Could be something similar?
 
I'm not fully caught up on the conversation regarding the hood flutter issue, but I took my OT in for the 5k freebie service and asked them about the issue. I've noticed it since day 1 but it's not something that really bothers me; but regardless, I brought up the issue with the service rep at my Lexus dealer (Greenville, SC).

They informed me that they do have a fix for the hood flutter issue, however it would require that the car goes to a body shop. They didn't give me any exact details about what that fix at the body shop entails. Hope this helps shed some light on the issue!
