My mom's 635Csi has a stromung exhaust. It sounds really deep, but isn't obnoxious. It has a nice purr to it when you let off the gas and just coast and it growls when you stomp on it. The tips look cool too. They flare out slightly and have a neat honeycomb pattern on the inside. I've never seen them advertised anywhere though. It was on the car when she bought it.
