Default high pitch noise while cruising.

ok so while cruising in 6th on the frwy at 70+ mph I get a whistling noise when slightly pressing on the gas to stay same speed (level or downhill roads)...press a little more and it goes away or my exhaust drowns it out...

That sounds like you might have a bearing going out in your transmission or rear end.

My 08 z does the same thing. Does it do it only in 6th or all gears? Mine is all gears and I think its input shaft bearing.
