I have a dull growling noise on my 07 sts sg1 6 sp auto n*v8 RWD that sounds like deep base on the radio and it occurs between 40 and 60 mph. And it starts making the noise when driving with light gas pedal touch in final drive gear, it doesn't make the noise when accelerating or coasting.
I had a similar noise on my '06, it ended up being the rear-end; it was replaced under CPO. Not knowing where your sound eminates from, it's a tough call (could be anywhere in the drive train); might be time to bring it in (I'm guessing it's bound to get worse if left alone).
