Just received a 2025 in the US with the dynamic Amg package and optioned out.

I have “race” mode and Amg dynamics “master” but there is nothing for exhaust like I’ve seen on other videos.

my dealer here in west palm doesn’t have a clue. Every model I’ve seen has it either on the left dial on the steering wheel or it’s in the Amg dynamics big screen on the right side. I’ve tried to add it to the dial and searched but it’s no where to be found?

 

I ask because I can’t get a single pop or burble in race or sport + is upsetting. The only answer I got from my dealer was “the exhaust needs to be broken in”

 

I don't see that colour often on the CLE 53 : )

As for the exhaust:

It seems that the car was not ordered with option 339 - Switchable Engine Sound?

 

My dealer told me it was strictly just noise in cabin through the speakers…. To me that sounded super cheesy on an Amg.

Im early 30s…. The car is beautiful but what a disappointment.

I went from a c63 - to a Maserati GT - to this.
as much hate as Maserati gets… they sound absolutely amazing.

 

Thank you honestly pictures don’t do it justice lol…. I’m sure in the next year or so renntech will come out with something. I’m just down the road from them.

 

Yeah. I hate the idea of piped-in sound. My Jaguar F-Type had it (They call it "Symposer") . I disabled it, but kept the valve functionality (of course). It sounded awesome with the valve open before and after disabling Symposer.

The AMG CLE53 also has valves, and piped-in sound. As far as I know (someone please correct me if I'm wrong - my car is currently in production) the AMG CLE53 only provides the valve on systems that have that "switchable" option.

 

Yes you are correct. 2024 models it came standard. 2025 models it’s an option.

 

Thanks! Then I am glad that I got it. I want the valve. I'll probably try to figure a simple way to disable the interior part of the sound.

What Jag's Symposer did was literally pipe in sound from the intake manifold. A tube runs from the manifold into a switchable valve (with integral resonator?). The output from the Symposer is another tube - this one connects to the firewall through a megaphone which looks like a funnel. So, in the Jag, all one has to do is cut and plug the hoses. (It is next to impossible to remove the entire system without removing the engine.). But the Jag exhaust (supercharged V6) with the exhaust valve open sounds terrific by itself.

From what I gather from Mercedes literature, their system uses microphones (they call "sensors") that pick up the exhaust sound, amplify it and run it through the speakers. Hopefully, disabling it is simply a matter of disconnecting the mics at the connectors.

 

You can turn it off in the cabin and keep the valves open. That’s how I felt with my Maserati I don’t think there’s a better sounding v6.

also I do think there some hope after the break in period. I’m on 500 miles now and can hear a noticeable difference from last week. I swore I was driving a Tesla lol

 

I saw the colour in person very uncommon but very nice under the sun.

 

The cars with 'the sound' control are equipped with AMG Real Performance Sound which pumps the sound through the speakers

 

No kidding! If you read the thread above, we discuss this. There are two components to the sound: Internal (microphone -> amplifier - > speakers); and External (valve).

Some of us would like to decouple the internal sound from the external.

 

I‘ve done some more research and am weighing on again on this topic since the subject of CLE53 Exhaust came up again.

First, the reason European cars are quieter than in the past is due to new EU regulations, see attached.

Second, there now seems to be two exhaust options, with or without Switchable Performance Sound, (339).

On the issue of the Switchable Performance Sound/AMG Real Performance Sound (semantics I think), the question is does the lack of this option also eliminate the valves after the mufflers too? Mr. AMG on youtube has a vid saying that his UK spec car has no “AMG Real Performance Sound” option. He doesn’t say anything about valves but it doesn’t sound like his car has them.


As far as the source of the “pumped into the cabin sound”, I found this:

Real Performance Soundis a system used in certain Mercedes-Benz models, such as the A 45 S 4MATIC+. It records the sound of the exhaust using a pressure sensor and amplifies it electro-acoustically in the interior

Suspiciously in the “Feel Electric” page…

Those of us who have this option can attest to the fact that the pumped in sound does NOT sound like a real exhaust note amplified electrically by microphones, it’s somewhat louder in the car, but there are no real burbles, etc. and, and to me, it sounds more like an annoying dull thud between gear shifts. Rather, I believe that the “electro-acoustic” amplification is similar to what was described above in the Jag, a sensor in the intake in that case. I think that I may have found the “sensor” in the CLE53 and it’s in the exhaust pipe just ahead of the resonator.




I suspect that this tube takes sound pressure from the exhaust and pipes it to the cabin where it’s amplified using some kind of electronic megaphone. To confirm that the sound is not from a microphone and sent through the speakers, I turned off the entire MBUX system and the pumped in sound is still present. But I’m going to confirm this before I start disconnecting it.

I’ve contacted RennTech and requested to be notified when the have performance mufflers for the CLE53. It should look something like this from the E63s on their website:

 

I really enjoy exhaust sounds and I do not like this piped in "thud". It is very disappointing for a car in this price range. I only turn on the AMG exhaust sound with the top down and it is a little more bearable than in an enclosed vehicle. I hope somebody comes up with a fix that does not involve hacking off the exhaust system and replacing it. It is especially bad if I have recently driven my Corvette with the snappy, burbling noises it makes with the dual clutch transmission and the exhaust valves set to the loudest setting. Of course the Mercedes is a lot easier to get in and out of, has better visibility and rides a lot smoother.

 

One of us should try disconnecting and capping the tubes.
