It's two-fold. One is that cars are getting more and more sound-deadening, isolating the driver more and more, but it's also got to be partially that so many cars are coming with turbo-chargers which inevitably muffle the exhaust note. My T5 855 doesn't sound anything like the NA 850's (which sound surprisingly good stock).
I still think it's silly though. Every car has a sound, and I want to hear what it really sounds like, because that's a big sensation telling me everything is OK.

Someone will probably find a easier way to remove it, maybe find the module in the car and rip it out. However for all we know that will just end up throwing a code

its sad but like all the honda threads, I just feel BMW but more specifically M has lost its way. If you want a more powerful 5 series that is soft and luxurious, by a 550. If you want one that is sportier with more performance intentions, by an M5 that has less sound deadening that's more of a drivers car. Remember when they didn't make the M8 because they deemed it too heavy and too much of a GT car to me part of the M division? clearly they've changed their ways. Forgive me for not knowing, but do they sell a whole lot of these m5/m6's now? Ive seen a few E60 M5's around but not one of these.
Everybody who plays at this level (or above) uses some sort of trickery for engine noise. Porsche uses noise pipes in the Panamera, even.
That's the price you pay for day-to-day refinement.
There is a perfectly logical explanation as to why they had to add some soundtrack artificially. This is due to the layout of the engine. If you remember, the intake and exhaust tracks are reversed on this engine with the exhaust manifold/turbos in the V and TWO separate plastic intake manifolds that run along the outside edges of each cylinder bank. Therein lies the problem:
Most/all car manufacturers use induction noise to add a sporty flair to their cars, in fact whenever you listen to the car commercials you are hearing induction noises almost exclusively. People associate these sounds with sportiness and they are more pleasing to the general audience than a louder exhaust. Sure they could uncork the exhaust more, but people are much more broadly spaced with opinions on exhaust drone, boom, etc. BMW can't rely on this engine for essentially ANY induction noise because with the intake manifold divorced the way they are, it would sound like two funky 4 cylinders whacking away under there. Obviously this aural characteristic is completely unacceptable in the USA BMWs, much less a V8 M series. So no induction noises can make it to the driver, and they are limited on being fairly conservative on the exhaust note to appeal to as many customers as possible. Time to add some soundtrack using the speakers.
I'm sure the aftermarket will more than address the exhaust note complaints. While turbos do muffle the note more than an NA setup, you can still make plenty of noise as you drop heavy mufflers and resonators.
