5AT Exhaust Drone

Sound resonance is just a factor of pipe length x RPM. The Invidia pipe length was tuned for sound & power at high RPMs. Driving it at low RPMs is going to drone. You're right in the fact that the AT likes to drop RPMs down to the 1500 range when you're cruising, and Invidia did not tune their pipes for this low of an exhaust flow.
You could have a muffler shop add resonators into the mid pipes to help with dampening but the difference would be minimal. There's not much you can do here except live with it or sell the exhaust and get one designed for sound throughout the rev range, like the Nismo.
