This is why Eisenmann spends months on RD to get the right sound without the dreaded drone before they release it to the public for sale, while other companies just spit something out in order to sell it first.
Agree. I wonder if given the choice, say if a drone was an optional extra with the car, how many would happily would take it? "Would sir like the optional drone? It is tuned to highway cruising speed." "Oh yes please."

It's a pity that those lucky ones who don't have it or it's such that they don't mind, should brand the ones who do have it as a bunch of cry-babies complaining about a bit of noise.
My car is booked in to an exhaust specialist on the 14th for them to sort it out.
I have told them I want a louder (yes, LOUDER) amd more meaningful exhaust but without this damned unpleasant drone. I want something that will have me winding the windows down just to hear it. I think the 1M is too quiet about what it can do.
Even if the dealer gets on about the warranty thing this drone will have to go and I will post the result when it's done.
Look forward to your results. Mine seems to fall into the annoying category with a drone zone in 6th around the 2100 - 2400 rpm range most prominent.
It amazes me that those without a 1M feel qualified to comment on this issue. Some drones are tolerable whilst others are just plain irritating. I've had plenty of cars and bikes with modified exhausts; some droned some didn't. The 1M is a great car and does all I expected of it however the drone is inexcusable for the simple reasons that it is annoyingly intrusive and more importantly, this is a BMW
. Not some amateur home built effort. Why the engineers, with all of the resources of BMW, couldn't refine this exhaust to eliminate a drone is a question worth an answer.
