Don't have one within easy access, plan to compare soon by either asking to test drive my dealers prefacelift c63s or by asking an owner of one at one of our meet ups

But in any case, am quite happy the way it is now as I was expecting much worse based on all the threads floating around.

 

I have a ex demo at 1100 miles and having had a 14 plate c63 this version def doesn’t crack and pop like I’d want it to. I’ve had rs6’s, Porsche panameras (more pops but not engine gruff)and they all have More character as far as engine pops and crackles (rs6 was a 15 plate, Remus exhaust stage2) however this wagon is epic - just need the exhaust Notes to be fixed ! Are we any nearer?

 

Apparently Hyundai has figured this out better lol

 

sorry , had too...

 

Just watched rokenr's unveiling of his GT63S four door in the UK and it's clear that this car was unaffected by the changes and is loud and proud as ever, popping and banging consistently when revved up and stationary. This has to give us some hope of a software fix surely... Emissions and regulations wise they're equivalent surely?

 

I've just finished watching that video too Looks like an epic car, really interested in hearing what @roken thinks in comparison to the noise of his C63s.

 

This was posted by another member in a different thread but gives some AMG insight on what's going on with pops and cackles: https://www.caradvice.com.au/778969/...cla45-exhaust/

 

Doesn't sounds like we will get our c63s back to pops and crackles like b4

 

From the article, " For those curious to know, the A45 is a little louder than the CLA45 because of its chassis style but also, in order to fix the sound, all that is required is an exhaust change as the software will adapt to the better-breathing system.". Well get on then guys haha, test this out!

 

The article is Irrelevant to the facelift C63S. The other 2019+ V8 AMG pop and bang.

 

Here is mine pre-facelift - Sec cat delete. No tune. Like a machine gun lol.

Outdoor in the open - No underground car park BS.


I cannot live without this sound... I drive this daily.

 

Sounds awesome. You hitting about 6K on those revs? That's what it sounds like to me. I'm going to do a video of mine and post as well.

 

After 5k it pops like crazy.

But I get pops from 2k onwards - Have a look.

 

Nice. Btw wheels look great.

 

Does the cat delete work on the 2019 facelift c63s? Is it really that simple to fix?

 

I am surprised MB AMG haven't say anything about this problem

 

They don’t give a shyt

 

Let them know about it here :

don't see this is going anywhere unless you want to sue them for false advertising.

 

At this stage I want one of two things (in order of preference):

(1) A fix to the issue in the form of a software update. AMG could make the exhaust note software update optional, or even not offer it to customers in countries/states where it may run afoul of emissions or noise regulations.

(2) An explanation and apology from Mercedes Benz and AMG to all of the affected owners. To me, the complete lack of acknowledgement and response from Mercedes is very frustrating. Not every company can always please its customers, but failing to even acknowledge that a major customer issue exists is very disappointing.

 

By the description of this article, it appears as if the exhaust system was designed for the new A45/CLA45 to restrict the sound levels, and it may not be just a software control. And if this similarly re-designed exhaust system in the 2019 C63/C63S is the culprit for the reduced sound levels, would a software fix be even sufficient? I agree though, MB might have other tweaks they could possibly do it in software for improving the sound characteristics.

Is it in theory possible to take the C63S pre-FL exhaust components and fit it on a FL C63S ? Would that help get more data points on this issue?

 

UK version of the 2019 C63s seems to pop and bang ok. Listen to beginning and about 6 mins in.


Is it just the US version which is quieter?

 

Is this a press car? I didn't watch the whole video but sounds like it was given to him by MB UK to film a video.

 

Depends what you mean by a press car. This car was registered in the UK between Sept 18 and Feb 19, so somewhat after the press cars which most people tested back in June/July 2018 at Billster Berg in Germany. No reason to believe that this isn't a standard UK car.

 

Mine is a UK car and it's roughly in line with what others have found with their customer cars - it pops/bangs on demand in sport+/race when lifting off around/over 3krpm. Doesn't pop/bang at all on downshift no matter how hard I try. Will pop/bang when stationary and revving in sport+/race.

I've got an ASR module fitted to mine that keeps the rear valves constantly open, I must get around to recording some sound clips to share... Sounds a good deal more aggressive lower down when enabled.
