Ah I hear it, sounds like a wastegate although still pretty far from it but then it does sound like brake pads grinding rotors like another forum member mentioned. Please keep in mind that brake pads are always touching on rotors even if you are not braking so it doesn't have to move into position when you apply the brakes improving safety. It is just that, when you don't apply brakes, it doesn't apply any pressure.
Does the sound get louder when you cold start and drive in the morning and/or when outside temperatures are low?
