BMW's "Acoustic Damper" it's a servo controlled noise flapper. Closes to keep the noise down for low RPMs then opens with the throttle. I took it out with the stock pipe for a bit more sound which made the stock muffler sound much better. Without it the Akrapovic can is a real head turner, just too loud.
Put it back in today. Just right now with a deep rumble.
