I found a local dealer with a couple of coupes in stock and went to drive one today to get my first impressions while waiting for mine. I wasn't a good boy and punched it in Sport+ To be honest, I didn't pay particular attention to this. Too much other information to process, but the car sounds great and throaty when you get on it. I'm pretty sure it popped and crackled, but it blends in and doesn't sound artificial like on other cars. The sales guy next to me giggled more than I did. Take it through a tunnel with the windows down to get an impression of what it sounds like from the outside or have a friend rev it while you stand behind it.

AFAIK this whole "snap crackle and pop" thing is wholly/entirely due to injection of fuel software programming, the engine doesn't just do it by default (this applies to all car makes) if it's not doing it you may require a software update.

A change of exhaust or deletion of mufflers/cats will amplify it, but if it's not there to begin with it won't automatically do it after exhaust mods either.

Aust. bound '19 updated C63's are beginning to land here, I'm inline for a thorough test drive sometime soon, will be able to report on impressions then

Also, FWIW, on another thread here, somebody recorded the new emotion start. It's not the best video and the sound cuts out a couple of times, but just about at the end you can here the beginning of a crackle. He didn't rev it very high and the video is short.

unfortunatly that video proves my point there is no crackle or pop what appeared to be a start of crackle actually is not i wish i am wrong ( well i bought the car already lol ) just trying to find a solution too

I have a US spec 2019.. it makes the shotguns in sport+ and race above 5k letting off the throttle in gear.. I’ve set off a number of car alarms.. also US models do not have the particle filter. Letting off the throttle at 4K in neutral gives some crackles and burbles but above 5k in gear is another animal.. the one we all want in the lower rpm range too.

Clear case of product misrepresentation. MBZ knew that there would be backlash and wouldn’t sell as many if they gave production models to Youtubers. I wouldn’t be surprised if there is lawsuit over this at some point. Incredibly unethical on MBZ’s part.

I don't visit other forums, but are there other cars where people discuss exhaust crackles and pops? Is the MB the only one? All I wanted was a throaty V8 exhaust.

If I had to guess, Mercedes may have been forced to reduce the snap crackles and pops because the unburnt fuel creating the pops, and the resulting heat further downstream in the exhaust, would have been bad for the new filter.

Just broke in my C63s...still no pops and crackles. I traded a 2018 for the 19 and I am so disappointed with the exhaust note...why would MB mess with a perfect sound. I am looking for a work around if anyone has one. Was planning on getting a stage 1 tune to see if it helps. Dealership told me there was a service bulletin to grease the exhaust dampers. Friend of mine had it done with no improvement.

Solution - remove stock exhaust and put aftermarket exhaust , add tune ... done.. or go get your 2018 back :-)

I know how you feel.

The first time you twist that dial to sport + or race and nothing happens is very disappointing.
But SuperSwiss made an observation which I’m beginning to subscribe to.

The car car reacts to your driving style more so than the previous models.

So having driven it gently, for the first 1000, it remains flat sound wise, but then after a few aggressively
driven miles, it begins to pop, crackle and blip the throttle. However, not as much as pre facelift, but decent enough.

Now that been the case, one wonders why AMG don’t just say so in order to put our minds at rest.

I own a 2018 amg c63s by the grace of God still. I traded her in on a 2019 amg c63s having fell in love with the facelift. I test drove the car and noticed the exhaust just didn’t seem the same as my ‘18 when she was brand new. I drove home that night and got sick to my stomach on the ride, realizing the exhaust just didn’t sound the same. The exhaust noise seemed to be more forward in the cabin than outback like it was in my ‘18. I called the dealer the next day and they asked I bring the car in for a look and have their AMG specialist take for a test drive. They looked the car over and found nothing. We took my ‘18 for a spin and the AMG guy said exactly what I would expect... We then took the ‘19 for a spin and much to his astonishment the ‘19 in his words sucks! He was beside himself that AMG would mess with the best sounding car they produce. He turned to me and said, “man I thought I was going to look at you and say you’re nuts” but he agreed and was quite upset. Be forewarned the ‘19 does not have the same sound and probably won’t.

The dealership “Fort Washington, PA” were unbelievable, wanting me to be happy they ripped up the paperwork, gave me back my deposit and sent me on my merry way in my ‘18. Can’t say enough about them, class-act.

I have heard the ‘19s on the first shipment to the US were stuck on the docks for a while due to a tune to the exhaust so they would be emissions compliant. Just my experience

I don't have an '18 to fall back on, so I will be getting a '20 and enjoying the hell out of it since it's still a better car than an M4, RS5, or RC-F despite the changes to the sound. And since I've never driven a pre-facelift model I won't know what I'm missing. The 2019 that I test drove sounded wonderful to me, and when I got back into my M4 to go home I was already craving the sound of the C63. It's gonna be a long wait to November.

I know what you mean Sailinman. I would never give up my 2018 for a facelift. Although I like the facelift grill. I like mine just as much. Also love the Designo platinum white leather package with the silver seat belts, which is not available in the face lift. Looks awesome with the designo diamond white metallic. Glad it worked out for you and yes that was awesome of the dealer to do that.

Nice looking vehicle benzbell👍🏻👍🏻

Had to trim them down to upload

I find it extremely amusing that those who traded up from a pre-face lift to the facelift model are disappointed with the sound in the new model. Who was forcing you to trade in your 2018 for a 2019. Didn’t you test drive it to see if the sound was the same or different?

Personally I love the sound of the face lift. I test drove the M4 and RS5 back to back with the AMG C63s and loved it.

The RS5 actually sounded pretty good as in Australia it comes standard with the AWE Exhaust.

That’s nice. Thanks for the input.

GreyghostC63s, I’m happy to hear you’re so easily amused at others misfortune. Funny on every forum you go on you always have a guy/gal who can’t keep to a subject but instead has to make comments about people or their experience.

I guess you’ve never had buyers remorse. You go to a dealership where you take a short test drive, notice the sound seems a lil different but are told all the parts in the exhaust are identical. They even pull out a parts book and do a comparison, so you drive away in your new vehicle that btw you’re incredibly excited about. I was lucky to get my ‘18 back but others not... Good luck with your facelift model, I hope you pull up next to a pre cause you’ll think of me and others who have posted about their misfortune and realize you have the weakest sounding AMG C63s to date. Oh and when you make a phone call from you’re new car, enjoy the fact people on the other end won’t be able to hear you all that well since they pipe the exhaust into the cabin. Another reason I took mine back but I’m sure you test the bluetooth phone connection at the dealer before you buy 😉

Facelift sounds way more mature and refined. Different strokes for different folks.

threads like these just tell me my taste in the sound is perfectly in line: https://mbworld.org/forums/c-class-w...50-2015-a.html

every car under the sun is trying to replicate this fad - and it's already disseminated among ridiculous cars that I am grateful to not have any association with.

Enjoy the V8 noise - get an aftermarket exhaust if it's not loud enough (the same thing people have been doing for ages)

😂😂😂😂 I like the sound of the 18 C63 too but couldn’t car less if mine sounds weaker or has less crackle and pop. In fact I think the 6.3L C63 sounds better than all of them but My identity is not tied to how my car sounds. What I find amusing is not the misfortune but rather if someone has an MY18 model with an exhaust sound that they love, why bother changing to the 19 for the sake of a new grille and some extra buttons on a steering wheel. The upgraditis is the funny portion. I do hope you didn’t suffer any financial loss from changing back.

Did anyone do secondary cat delete on 2019+ C63s? Can something make the car sound better at all?

Has yours started to get the crackles and bangs after break in?
