Active sound covers it up I think

I've had 2 6 GCs and a coupe and heard it on all. You need the stereo off and it only does it when you drop down heavily and then accelerate pretty hard

There's a dual carriage way near me, I sometimes need to brake from 50 or so and then Accelerate up from 10.... That's really the only place I hear it. But as I do that road everyday I have noticed it only happens at those lights, otherwise I never hear it
