Their website sells an accessory which has a spring to keep the valve closed but changes the sound to a more high pitched noise, which I don't want... Anyone confirm this?

If you recirculate the BOV then that is not an issue - don't put the anti stall on it since you lose the MPG savings you get when the BOV is open at idle and cruise.
