Yes, I also read that on the US forum. I'd expect a genuine BMW exhaust not to have any serious drone issues, but I think it still depends a bit on the user's preference for sound. I still intend to get a Eisenmann muffler but I'm going to leave it until around mid year, mainly because I'll be taking my car to the dealer for some warranty work and servicing.
