The sound you are hearing is air leaking across a damaged gasket or a warped sealing surface. With the throttle closed, or in deceleration mode, the manifold pressure is very low and if there is a leak anywhere in the induction system that should normally be sealed, you will hear the (very common) whistle.

Why is my car making a whistling sound when I press on the gas?
If you hear a whistling sound while driving, there are a few different places you can check out to find a probable cause. The most common reason for this noise being made is a vacuum leak, due to worn or cracked hoses.
Why is my car making a high-pitched noise when I accelerate?
If you hear a high-pitched squeal from a car when moving, it is most probably caused by a loose belt in the engine bay. ... If the belt gets loose, it can result in the car squealing when accelerating. Since the belt is not under the proper tension, it slips on the pulleys and creates a sharp, high-pitched noise.
Why does my throttle body whistle?
Why does my throttle body whistle? ... ' The air along the outer edges of the air intake system and throttle body hits the "wall" of the smaller intake manifold, creating turbulence that can cause a noticeable whistle.
Why does my intake whistle?
This high-pitched sound is typically the sign of low return airflow. In other words, your system's blower is “starved for air.” It's trying to pull in a certain amount of air, but is struggling to do so. As this happens pressure and velocity increases, therefore increasing the sound level (that's the sound you hear).
