Yesterday at the dealer I brought this up and they were adamant the speakers are not involved in enhancing the sound experience and directly accused BMW of doing just that. You however, read the description for PE and this is what it says:
"The powerful sound of a Mercedes-AMG is an unmistakable signature, from its snarling startup growl to its assertive throaty rumble as its unleashes its power. Computer-controlled vanes near the tailpipes of the AMG exhaust system also let the driver escalate its sound at the push of a button, while the system's free-flow design delivers an audible celebration of power with every upshift, downshift and rev."
So if you have this option installed, its just basically opening and closing baffles to either enhance or mute the sound. I remember reading an article a while ago about this but can't find it now. Since it is an AMG tuned only engine, maybe the exhaust portion is also tuned by them in a similar manner.

I’ve looked into this and I have found no involvement of the sound system for the PE option.
The rear mufflers with integrated flaps are of the same design as the ones on the C63, minus the center flap in the front section of the C63.
And by the way, you lucky dog, you brits get to have the boot available.
Thanks, yes I prefer the estate over the saloon, better rear styling IMO, and louder exhaust inside the car.
Obviously the extra practicality too.
I'm sure they'd sell well In the US, don't see the logic of selling them in Canada and not US.
Why should the exhaust be connected to the sound system?
Whenever you activate sport+ a modul on the right side of the Trunk plays engine sounds throught the speakers.

That’s the exhaust control unit that I mentioned,
not the exhaust system. It controls the muffler flaps. The wires go from the control unit to the muffler flaps. Are you saying that the same control module controls flap angle and outputs audio?

For some reason, Americans as a whole have an aversion against Estate (Boots) or what we call here Station Wagons. Out of the very few car makers who offer one, VW just announced it will kill the sales of it here. Audi has the allroad but with only one engine option, the 2.0 turbo. All others with the exception of the Jaguar one are boring. The Volvo one is nice just not enough power. I don't get what the issue is so I was excited when I saw the Merc CLA 45S Estate but unsure if it will be available here.
Alright, do whatever you want. I'm tired of arguing with Muricans, they always think they know EVERYTHING.
Good luck when you change the Audio System in your C43 and suddenly your ears are getting BLASTED away by the speakers

Okay so that’s a different control unit than I was referring to. I was referring to the control unit for exhaust flaps specific to U78 PE exhaust, and you’ve highlighted a different one for sound. However, I’d like to point out that the control unit you referred to doesn’t seem to be unique to U78 PE optioned cars only. Why do you perceived that anyone is arguing here? I’ve never claimed I know everything, nor should you I would think.
wasn't this confirmed on the pre facelift? not sure why it would be different..
Confirmed by two separate owners in the C43/450/400 general WhatsApp chat that removing fuse 424 in the trunk panel makes an impact on cabin exhaust noise. Call it whatever you want, but the cars makes additional noise through the speakers to enhance the exhaust sound in the cabin with PE.
Edit: Also want to point out that this hasn't been confirmed with non-PE cars as far as I'm aware. I'm non-PE, so I'll test over lunch today and report back.

I don’t know yet, but a search on those sound generators that Malar posted are only found in the Coupe and Cabriolet C43 and are referred as engine noise over speaker and one is referred to as switchable exhaust. However, on the Sedan and Estate with PE, there isn’t this switchable exhaust sound generator control unit.

On Cabriolet and Coupe there is a control unit specifically for PE. I discovered this after Malar pointed it out. However, on Sedan and Estate, the control unit Specific to PE is not there. There is a sound generator, but I don’t think one can conclusively say it’s exhaust sound being piped into the sound system in Sedan and Estate. Maybe noise cancelling? But it’s confirmed that Coupe and Cabriolet have a PE sound generator.
1) C43 all variants have a Sound Generator Control Unit.
2) Only C43 Cabriolet and Coupe additionally have a Switchable Exhaust U78 Sound Generator and only if equipped with option B63 it has a Engine Noise Over Speaker Sound Generator Control Unit.
3) C43 Sedan and Estate do not have U78 and B63 specific Sound Generators.

To-may-to, to-mah-to, IMO. Aren't a pirate's peg leg and a carbon fiber leg both prosthetics? If there is any sort of audio intervention happening that aids in the perceived engine/exhaust noise inside the cabin, whether it be pre-recorded engine/exhaust noise or just similar audio frequencies, then the answer to the thread title question is simply yes. Those willing and aptly concerned about it should go pull the fuse, drive and report back with their results.

A2059006226 is not found in any C43 variant.
A2059006928 is found only in Coupe and Cabriolet C43, and is not a PE sound generator, it’s an engine noise generator. 🤣

Really? I’m the bad guy? I’m trying to help, not dismiss others with sweeping statements.
There is a specific sound generator for PE exhaust, and it is not fitted on PE equipped Sedan or Estate. So I can definitely say the exhaust sound isn’t piped into the cabin in those instances.

Uhh...what are you getting defensive about? Where did I call you the bad guy? You questioned whether it was "noise cancelling" and I simply pointed out that it's one in the same, and proposed those with specific models should test said hypothesis. Chill out Francis...jesus

Okay I got it. It's fine. In any case, I just wanted to point out that because Malar mentioned it, I've found that there is an Engine Noise sound generator and also a Switchable Exhaust sound generator, but they are not installed in the Sedan and Estate models. I think it's Malar that needs to chill Haha

This isn’ t the first time Malar makes dumbass comments about “Americans”. Dude has got some serious issues.
