You need a turbo and a BOV. The sound you hear is the charge pipe relieving
pressure when the throttle shuts and the manifold is in vacuum. The vacuum
signals the bov to open. Bosch plastic BOV is about US$20
Alternatively you can buy one of those recorded sound units with a speaker and act like you have one, although I can't understand why anyone would want to hear air escaping in the first place.
