F10 M5 exhaust bangs and crackles through the gears
Discussion
Yesterday once the car was warm I went through the gears in M2, Sport, Sport, Sport (or whatever the max settings are less MDM) through some tight tree lined twistees with the window down and what a noise the car makes going through the gears.
Bangs and crackles from the rear especially going from second to third sound great from the drivers seat, I'd love to hear them from the outside!
The more I drive the car the more I love it, it's an absolute work of art

Totally agree...I know we could be deemed as biased but those who talk this crap about how poor the car sounds tends to be by people who have absolutely no first hand experience of it.
I've owned some nice sounding cars and whilst it might be stretching to say the BMW is right up there with the AMG's etc., it does have its own unique appeal. The exhaust design gives it quite an exotic sound not dissimilar to a flat plane crank engine. There's no doubt it sounds great from the outside; it is a shame that you have to wind down the window to benefit from it.
Interestingly, I pulled the audio fuse last week to see what it sounds like without the symposer. Honestly, it was too quiet - you could hear marginally more of the exhaust pops and bangs but there was almost nothing from the engine, even revving through 5-6k rpm. And despite all the ridicule the symposer gets, what tiny bit of engine noise I could hear was 100% identical to the louder sound you get with the symposer, largely confirming that the symposer simply amplifies the actual engine noise, not create a different 'fake' noise.

Not sure, according to this article, the M5's symposer noise is a pre-recorded track of the same engine from the outside :"M division engineers discovered that the F10 chassis, like that of so many other new cars these days, is so effective at insulating the cabin from road and engine noise that the M5 lost one of the characteristics that made the previous two iterations such visceral thrills to let off the leash: its bark. To give the driver a better feel for the engine, an exterior recording of the M5’s motor plays through the car’s stereo. The precise sample is determined by engine load and rpm. Some of the real engine notes are still audible to the driver, so the recording is more of a backing track. BMW says the setup helps the driver shift by ear and reduces the chances of bumping the rev limiter when using the full rpm range."

Thing I love doing is 3rd gear at 1.3k rpm. Accelerate hard then just as the turbos start blowing hard at 2k rpm shift to 4th and lift right off at the same time. Car lets off an addictive baaaaarp!
Especially good in tunnels, also length of burp depends on fuel used

What is fake or manufactured is interesting, AMG "manufacture" the sound via the exhaust, the engine noise isn't really there, the S54 and S65/85 produced real engine induction that you can hear, not trick exhaust pops, crackles and bangs which appears to be in vogue with Jag and Merc.
My old PSE on my 911 did the same thing but you knew it was engineered/designed in and not a natural by product of the engineering which is the case with the old n/a M engines.
BMW are just following what has been done before but via a different route.

I'd like to try his. How easy a job was it?
Here's a picture I've lifted from another forum - the fusebox itself is located behind a flap on the right hand side of the boot and you just need to pull the fuse that the chap in the picture is pointing to. Trust me, you'll be putting it back pretty sharpish as it doesn't sound impressive at all without the symposer!
ETA - when you do this, your radio won't work at all so this is only suitable as a temporary trial of how the car could sound if you had the symposer permanently disabled by coding.
