the sound is coming from the intake/airflow. it's just the change in air volume being sucked into the motor when releasing the throttle for a shift. this noise will only occur is you shift very quickly and don't fully let off throttle. sounds bov-ish, but not really. if i had a turbo you would have heard the bov poppin when i was reving at launch.
