I have had it in 4 times for the same thing and they replaced the exhaust from the cads all the way back, and it still makes the same noise.

You can hear a mechanical sound when you lightly give it gas and let off. Kind of a buzzing sound like the flaps are opening and closing.
Have you considered the option of going to a dealership for a proper diagnosis? They should be able to pinpoint the issue you are experiencing. Please let us know if you would like to set up an appointment with your local dealership's service department!
