Anyone here thinks the differential is a bit noisy in the following conditions?

1. Highway cruising 75 MPH, 6th gear, gas pedal very slightly open as to keep the speed. (Some sort of annoying high pitch noise is heard)

2. Street cruising 40 MPH, 4th gear, gas pedal slightly open as to keep speed. (Annoying high pitch noise)

I am assuming it is from the differential but cannot be 100% sure.

I would love any help in this matter.

I took it to the dealership and they said it was normal noise yet I went to test drive another Z and though there is a similar background noise it is not even closely as pronounced...
