Roiiken stated that if they made an e63 coupe, it would destroy the rest of the lineup because it simply would be the best. I think he's definitely right. That's why the e53 came in.

Fact of the matter eventually the hybrid tech will take over the turbo tech, the same was turbo tech is taking over NA now.

The easy answer is: If they come with these filters, then yes of course. Just cut it out and install/weld straight pipe. Simple.

However, if they have changed the computer engine management or emission systems since 2018 to accommodate these new filters, then removal of them likely will generate a check engine light, which also has big time warranty issues.

Let's hope these filters never make it to North America, per the last article I posted. My guess is they will be on all cars. Otherwise, why would they start the pipe in engine sound for 2019 in order to compensate for this?

It's already been published and confirmed that they are piping in sound for 2019.

Keep watching RBR's video past the start up scene when he is on the road accelerating into high revs, and you will hear the piped in sound and see his reaction. He compares it to the E63S sound.

They did this initially on the E63S because it was so more sound deadened inside than the C63S.

What I am wondering about is where exactly did they place this GDF for the C63s. The 2019 C43 is significantly quieter than the old ones because of the GDP. So I cannot believe that the new C63s will sound as loud as the old c63s from outside. Can't believe they decided to ruin this car just as I am preparing to place an order.

There is no other reason to get the C63s over the current M4 except for that growling and barking AMG V8. So I want it for the sound as well. Well the massive amount of torque is also very attractive. I just cannot bring myself to buy one of these cars used. Specially if the car was leased previously. People have a habit of not going easy on their leased cars. Probably dont even bother breaking them in, which would really really bother me. If I am buying my dream car, I am breaking in that car in myself. Having a lot of car friends, not one of them ever broke the engine in except me because the car was leased.

I am just going to wait it out so that the car gurus in mbworld can figure out a way to remove that GPF without turning on CELS. Or even better Mercedes does not put them in the NA versions at all.

Yes, the local dealership got a 19 C43 Wagon with perfonmance exhaust. The upshift bangs are completely gone and the lift off overruns are extremely short. Like 2 or 3 farts max. Two theories: either the filter has significantly quietened it, or Mercedes decided to make the burble tune significantly milder for the new C43. The C63 so far seems to be not that affected from the youtube videos. But I am waiting for some forum members to confirm.

I wouldn't trust that media car as 100% representative of how the final production car will sound. Media cars are notorious for being louder than the cars that hit dealerships.

The more you listen to the youtube posts of the 2019's (those videos with actual microphones at the exhaust pipes), and most importantly with ear phones on your computer, the more you will hear the weasing sound at full throttle caused directly by the new exhaust filter. It's like a clothes' dryer outlet clogged by lint.

It is night and day compared to the 2018. With exhaust flaps open, the 2018 has more straight pipe guttural sound at low revs. At the same time, the 2019 has the great piped in V8 intake sound at high revs., which is missing on the 2018.

Don't get me wrong, I love the updates to the 2019, and I will trade in my 2018 and buy one if I can easily remove these exhaust filters without generating a check engine light.

If AMG Mercedes was smart, it should have known that we would want to do this, and it would pre-design an easy removal of the filters (just like the V-8 Mustangs have done for years on their rear stock exhaust mufflers). Easy removal - bolt off, bolt on.

Completely agree - the more I think about it, the more I think this is the thin end of the wedge for people who love cars. 2019 C63 - changed sound, 2022 C63 losing the V8 and the sound, in 20 years time people won't be able to buy a non electric car, or even humans will be banned from driving their own cars. At least that is the direction of legislation in Europe.

Moral of the story - buy your car now and enjoy it while you can! :-) Hopefully a 2019 C63 with the GPF removed.

I've just driven to my office from MB World in a loan 2019 C63S Cabriolet whilst my C63 Black Series is being serviced and I was appalled by what I heard when I switched on the sports exhaust. It sounded just like the M4 I drove a couple of years back which I hated because it sounded so fake. The big issue is that the sound comes from all the speakers so it's all around you whereas real exhaust noise comes only from the rear. It doesn't matter what it sounds like when it is so obviously not real. As soon as I got into my office I searched the net in the hope that I was wrong and more importantly, any piped in noise is only on the coupe/convertible because I am putting together my order for a new C63S Estate to replace my 2015 car in October. Now that this thread has confirmed all facelift models will have piped in exhaust noise I am extremely disappointed. It's hard to believe I'm saying this because I was disappointed with my current C63S's fake (as in contrived) exhaust noise, pops and bangs when I changed from my previous W204 C63 which was much more real and pure. If piped in exhaust noise is a new fact of life then why can't AMG at least do it subtly and only pipe the noise in through the rear speakers to better simulate real exhaust noise? Thank goodness I can always turn to my Black Series!

Am I understanding correctly that 2019+ C63S have GPF, or only in Europe?

Also, is the exhaust note coming from speakers in all 2019+ C63S or just the one with GPF (Europe)?

japamg

Same thing happened to me. I actually changed to sport+ several times as I thought I was doing something wrong

LessIsMore

Sorry to hear that about the 2019+.
I have a 2017 C63 and I appreciate that it does not have fake exhaust noise piped or played in the cabin, its something I like about it. When so many cars are Resorting to artificial sound, along with a turbocharged 4 or 6, it its nice to know that you have an authentic sound (especially when its such an amazing V8 sound!).

Yeekai Lim

Anyone wanna sell me their 2018 performance exhaust? 100% muted. Doesn’t have the pops, bangs Or gurgles. Sounds more like the m4 sadly. Engine note on the other is still that v8 drum.

Just wanted to update this thread after a recent drive I had. I'm about done with my break in period for my facelift c63s and decided to go for a drive to get that break in mileage done, and decided to try out sport+ mode.

From my obersevation, I've been able to get consistent crackles and pops once I pass 3000rpm in 3rd/4th/5th gear and let off the throttle. I did this for 30 seconds non stop for about 7 sets of 30 seconds where I'd just get over 3000rpm and let off the throttle and let the exhaust crackle and pop, and without fail every single time it crackled and popped.

Downshift crackles and pops were almost as consistent as long as i hit 4.5-5000 rpm into the gear I was shifting into. Any lower than 4000rpm and it wouldn't pop at all.

Will do further testing, but for reference, I'm in Singapore, my build was an end February production

Hi all,
Just upgraded from my 2017 C63s to the 2019 facelift and have been very disappointed with the change in sound. The natural barking, pops and crackles are all now very subdued in comparison. Has anyone found a way to modify the latest version to get back that aggressiveness we all love in the pre-facelift version?

GSEH88

I wish I had a new car to be disappointed with! I have a 2015 C63S Estate and was due to change it for the latest model in September but until now, the dealer (largest in the UK) has not been able to confirm a production slot even though these have now been released for the UK up to the end of the year. I’m promised I’m number 1 on the list but that’s no use if MB isn’t making any. I did try the latest C63S Coupe and was very disappointed that sound is now piped in through the speakers but right now, getting hold of a car is the priority. And then I’ll start moaning about the noise afterwards

D28L

Did a bit of research and spoke to some automotive specialists.

One guy said he changed the down pipes and removed the OPF (putting in fakers so the warning lights don’t go on). This vid is the result:

Am unsure if the signature amg crackling and barking is still as easy to achieve in the low gears (and even in comfort) as preface lift but it’s definitely close!

I also visited another at his shop and he recommended changing the downpipes and tuning the ecu to get even more of the crackling back. Saw a facelift c63c there that also had full exhaust done. Sounded amazing.

There is hope!

quduoheng

you should not. I bought a 2017 c63 on purpose in 2020.

1. Because of the partical filter makes it sounds not as good, and it needs to induct the sound through speakers into the cabin.
2. 9 speedshift is just to put there for better fuel econ to meet certain regulation. In real lfe, 9 speed is confusing sometimes, even in auto mode. Imagine, you are crusing on highway at 9th(Manual), now you are about to overtake, then you need to click 4 times to get to the 5th, 5 times to get to the 4th. thats insane. And more gears mean more problems after a decade.
3. Digital screens have gone too far. Too much info, too much design. (The new ditial screens on BMW models look fancy, but hard to read too)

Uga Uga

Mine will kick down from 9th to 5th when I kick down in one go.
