Also available is the ExhaustMeister off my 750 - $75. Allows you to open the exhaust flap in the mufflers for a little more sound. Fits numerous BMWs as long as they have a vacuum controlled flap. My new F34 has an electronic one, so it won't work. Doesn't really change the sound much on the 750, because the car has 5 mufflers. Bypassing the rear two adds a bit of a rumble, but its not noticeable unless you're in a drive thru or something. Would work better on an E90/92, F10, or E70/71
