There is an ad on the forum for a diverter thingy that will give your inner ricer a thrill. It will make your R56 CS "whoosh" when you back off the throttle. Great if you are 16-years-old and own a MINI. BUT, I know from first hand experience, that there is something better -- a blowoff valve/diverter with a duck call. I have seen this in person, but did not video it. This YouTube video tells the story just as well. [ame="https://www.youtube.com/watch?v=p3TDbcjt7WU"]Mazda Protege 5 turbo duck call blowoff valve Mazfest 2008 - YouTube[/ame] We actually did this to a Subaru WRX, and laughed our arses off -- well, actually a turkey call. But, the duck call is funny, too. I'm tempted to buy that diverter thingy and a duck/turkey call for my MINI. I just need to get drunk enough. CD
