And if it's only 3%, why even bother with the development/implementation of it |

Unplug it, decode it, kill it, but stop the madness. [3% is a crock of shit BTW!] Would you like some cheese with your whine? |

Do we know how this compares to the F30? I had one as a loaner and the first time I revved it up I was pleasantly surprised with the noise. Five minutes later I was annoyed with it and could definitely tell that it was being amplified. It is impossible to recreate the exact sound through a stereo system.

Pretty much all newer BMW exhausts have valves in them now. Is that cheating too? And who makes the rules for what is right or wrong? There are/were so many more things I was concerned about when it comes to the M3/4 such as reliability, cooling, steering feel, ect... but some people are more concerned about 3% enhancement.

The exhaust system and it's sound is "all natural" with exhaust valves that bypass the rear muffler in certain conditions, creating what effectively is a straight through exhaust. Active noise only enhances induction/engine noise, not the exhaust. I guess they might have felt this necessary on the M cars since induction noise/roar has been such a big part of the noise inside the cabin on all the NA engined M cars. On a turbo engine, induction noise is muffled by the turbos. |

I hear a lot if "whiner" thrown around. So I guess Thomas Jefferson was a whiner because he didn't like what the Brits were doing. Many here seem to latch on the technicality that the intake or exhaust is only enhanced or amplified. What you forget is that the M5 whiners saved you from a worse soundtrack version that would be standard now if it weren't for the whiners! Then again maybe you guys would prefer that since it sounds better.

Induction noise is important to me of just the reason BMW state as why they fitted the active sound. It better connects the driver to what's going on with the engine.
1. After a while you no longer need the tach to determine shift points and if you are in the right gear for your intended driving. You can hear it from the induction noise or lack thereof. 2. You can use changes in tone to detect certain engine health issues. I think (1) will work just fine with active sound and will be helpful but I think it can take away the nuances needed for (2). I understand why they did it but I've driven and owned turbo cars before that didn't need it. If it isn't annoying I'll probably keep it but if it feels silly and detracts from the connection to the car with a lip-sync out of phase feel it has to go. |

With that being said, I got used to the level of the sound with the windows up - having taken delivery in March - and now that my windows are down more often, the car definitely sounds more quiet when active sound isn't working. My understanding is that the system is deactivated once the windows are down.

Just like the auto start/stop feature. People wanted the option to disable it and BMW answer by programming the car to remember the last set option of the customer. Now if you have it off it will always be off every time you start the car.

I see your point. You are correct. I really can not. But all I am saying is that 2-3% should be hardly noticeable, when in fact it sounds very noticeable in all the recordings of the f80/82 we have seen. It's kind of annoying actually. Almost like a droning noise.

1M sounds good. Not great like NA but sounds good. Some complained about a drone but personally I loved it. It's also basically the same motor. 3L online two turbo.

Hey guys, I've been poking around this forum for a while now and actually just put in an order for a mineral white M4 yesterday. I'm pretty excited about it to say the least. This is my first post. I'm interested in deactivating the digitally-enhanced engine noise. This is the only modification that I'd like to make to the car, and I'm guessing this isn't something that my dealer would be able to help with. I'm also concerned about possible warranty issues arising if I were to make such a modification. I'm not dead-set on eliminating the active sound feature but if there's a straightforward way of doing it without messing with the warranty, count me in.
