Every car I have owned started some sort of drone when the exhaust was opened up. Did I like it? Usually no, would I go back?? Emphatically no, not after the gains I received, plus I think my MPG increased. Oh ya add to that the drone exhaust sounds better at all the other RPMs and gears when its not droning.

Adding power has side effects.
I agree. If BMW said "we can eliminate the drone but you will lose power and / or the exhaust note", I would say leave it as it is. Do you have a 1M? If yes then you are qualified to comment on the particular drone this car produces as you would have experienced it. If not then you are only making a general comment about exhaust sounds not pertinent to the 1M's drone.

You seem to assume that you can only have a performance exhaust with a drone or a non performance exhaust without a drone. There are performance exhausts that produce more power and more sound without a drone. Why can't BMW do this? As I said, if there is a technical reason why they had to compromise with the exhaust then so can I.

But I doubt it.
