Sounds great, its top of my list of mods to do, I think that its a very inexpensive mod that enhances the driving experience loads.
as for the nay sayers - Ferarri, Lambo, Porsche and AM all pay extremely close attention to the sound that is generated into the cabin, using filters, hifi, sound deadening.
That BMW built this element into its cars shows that they are tuned in to their customers, and the fact that customers can opt to not use it allows them to make that choice also .....
