Wastegate (exaust gases valve), can make only scream which goes louder when the boost rises to the max if "equipped with screamer pipe". That rice sound is produced by the BOV whistle (don't mix it with turbo chatter - big boys have).

If you don't get it from text - here are the pictures:

Wastegate is that mushroom which grows under bonnet:


BOV with whistle (trumpet to make sound louder ant more pleasant):


Wastegate screamer pipe (small exaust tube which is for WG output gases only):
