I don't know, but it would stand to reason that this is partly due to the VVEL. If you think about it, valve lift/duration increases with revs, so essentially, the VVEL allows more and more air/fuel into the engine the higher you rev it, so it would only make sense that more power = more noise.

Either way, it almost has a different character in the high rpms/sounds like a different engine.

The one thing that DID surprise me about the powertrain is how much it sounds like a 4-banger. LOL. The engine just doesn't have the typical V6 smoothness that I was use to from my 2007 Altima 3.5SE. That's comparing apples to oranges, but you'd still expect a slight resemblance considering they're both Nissan V6's. But not so much.
