So are they confirming that North American C63s has indeed inherited the Gas Particulate Filter? If that is case, I am pretty sure the sound would significantly improved it is removed.

Unfair comparison with the exhausts considering the MPE is a $5K aftermarket (dealer-installed only) exhaust. A buddy has the same exhaust on his M4 Competition and it really does sound pretty good. Gets more attention while driving than my C63 does for sure.

Agree with the C63S being a better performance cruiser and the M4 being more raw. The C63S is comfortable, sounds great stock, and is a total beast that can put down excellent numbers on the track. The much lighter M4 is a better choice for someone looking for that sports-car track car feel. I will say though, the C63S is better at being a performance cruiser than the M4 is at being a sports car. If I wanted the full raw experience, I’d go for the 718 GT4. Two flavors of ice cream. Since this is my daily, I know which one’s my favorite

I currently drive the 2016 M4 convertible (non competition pack) and can't speak to the comparison since I have not driven the C63. But I can say that, although I know the competition pack is "better", I cannot imagine it totally transforms the vehicle. I'm sure the titanium exhaust sounds much better, but I just can't say that the M4 is soooo special and awesome. Don't get me wrong, I've loved mine, but it's just not an exciting car unless you're on a track. I don't know what that guy is talking about "so much low end torque." Unless the 20 additional HP makes the CP that much faster, the M4 is a slug at low RPMs...

Regarding the convertible aspects, the hard top alone makes the comparison between the cabrio's night and day. Although the general public loves the idea of a hard top, it's a detraction for the M4. It's *very* heavy with the roof up and you can feel the weight when driving around, even normal driving. Also, it creaks and squeaks like mad after 3.5 years...and you can't operate it while driving over 12 miles per hour, which is REALLY inconvenient. It takes almost 30 seconds to put up/down. These are all real detractions to this car. In short, i would not get a hard top convertible again if i could avoid it.

Anyway, for these reasons alone, and the fact that that one dude admitted he's a BMW fanboy, you can totally see that come through. I mean, the analog gauges??? I can't stand that about my M4...it looks soooo dated.

So, I have to take this review with a grain of salt. Sounds like they may not be wrong about the exhaust sound comparison though...that's been a consistent complaint from everyone as of late.

Ho-hum, two guys with GoPros and nothing better to do driving around two cars and giving their personal opinions. These shows are a dime a dozen on the Tube.

I agree with Xec, if you want a sports car get a Cayman GTS or GT4, although you won't be buying a 718 GT4 very soon. Those cars are raw, have handling that can't be beat, and if you go with the 981 (and likely the 718 GT4) versions sound fantastic.

Is there a dedicated thread discussing the loss of burbles, crackles, and pops from the exhaust?

On social media, I saw that rokenr was very unhappy with his facelifted C63's lack of dramatic exhaust sound. Didn't think much of it at the time. Saw a video posted on here a few weeks ago from some YouTuber I've never seen before discussing that same issue. And now this video.

I just recently started looking at getting back into a 63, but this is concerning me a bit. It won't be the determinant factor, but it'd be silly to dismiss it.

I wouldn't get the 2019 C63 with it's muted exhaust... not even worth the awesome digital screens. I WOULD consider the 2019 C63 only if I planned on a full cat-back exhaust (or whatever it took to get that particulate filter removed. I only purchased the C63 over the M3 because of the V8 and it's sound. Without those, might as well go for the M3.

Yeah, that sucks. I searched and found nearly a full page of threads re: the exhaust sound. I've only found one so far has what I'd actually consider in-depth discussion of the issue, what's causing it, etc. Would be nice if there was one "Sticky" thread addressing the issue.

The article was written by whom? BMW, I believe? And if you want to make it 'faster' in a stright line you can go to Dinan and his bag of tricks. He slaps on what? A BIGGER TURBO! Instant-on with little-to-no modulation. Read the reviews on that piece if you think I'm lying.

M4 sounds like ****, regardless of what exhaust configuration you put on it. Like a loud weed wacker or a quiet one. Pick your poison.

Uh...it's still got a V8 and the M3 doesn't. There's a lot more advantages to the V8 (and the C63 in general) than just how it sounds, and IMHO even the new C63s sound better than the M3/M4. It may not be as good as the pre-facelift cars, but I'll take it over the M4 and RS5 any day.

That's... what I just said. I bought the car for the V8 AND it's sound. And I agree with everything else you just said haha.

I switched from a 981 Cayman GTS which has what is probably considered one of the best exhaust sounds ever, and I'm not feeling any remorse in my C63S.

+1 for the V8

I’ve said this in other threads and I’ll say it again, the V8 was the main selling point for me. The low growl is just intoxicating and I actually love hearing it from outside of the car.

AMG would be unwise to not put a V8 in the W206.

The V8 was the main reason I got the C63S. For my personal preferences, it's also well rounded in many aspects compared to the M3/M4. I find the M3/M4 interiors to be very dated.

The M3/M4 are nice track cars if you care about precision driving, although Porsche edges BMW out in this aspect.

2019 C63S Coupe
I purchased a 2017 M3 Comp. on a Sat. evening after having owned 3 previous iterations of the M3 (E36, E46 and E90). I brought it back to the dealer Monday and got my E90 M3 back. There was so much road noise inside the cabin it gave me a headache. Sunday morning after washing the car I went for a drive to put breaking in miles on the car. After about 30 minutes driving back roads I literally wanted earplugs.

I put off buying a car for a while and was shopping for a used Porsche 911 in late 2018. By the way, trying to buy a used 911 is a pain in the ****. Haha!

Anyway, I swung by the Mercedes dealer to ask about the updated 2019 C63S Coupe. To my surprise, the salesmen told me they got two in just a few days ago. Test drove the car a few times. I love the interior, the nicer leather, tech, etc. The engine and exhaust sound great to me. Sure I'd probably enjoy the pops and bangs we seem to be lacking. The car taken as a whole is freaking badass. There are gives and takes with every car. Anyway, the proud owner of a 2019 C63S Coupe, Selenite Grey, black cross-spoke wheels, with red and black interior. No headaches driving this one.

For what it's worth....I considered an M3 before I bought my C63s. One thing I am not impressed with concerning BMW's is that they do not seem to age well. What I mean is that the fit and finish starts to break down, creaks, and it seems the BMW's have a host of issues as it ages. Now MB has its issues, but in my opinion the MB cars just age better.

Another thing...I bought a 2019 C63s so I don't know how the "pre-facelift" cars sounded, but good lord this car is quite loud just the way it is. I love starting the car cold start with the "emotional start" in my garage as it roars like a lion and is quite vocal. My wife said when I start it up in the garage, she can hear it on the second floor. Now don't get me wrong...I personally love a car with some great sound and would love to have it even more vocal while driving. I find that in comfort or sport mode, the sound is good, but in sport + mode it really roars especially at high RPM's. When I gun it at high RPM's in sport + mode, it is very loud and gets attention. As mentioned in other posts, the only time I hear pops, and burbles is in sport + mode

Just my 2 cents. I love my C63s. I have owned many cars, and this is one of my favorites for sure.

Mercedes has already hinted that an aftermarket exhaust with less obtrusion will make the pops and bangs come back as the ECU will adapt automatically to better breathing. So technically you can get the old sound back with the C63s, in which case it really is not a competition.

I personally see no reason why the C63s ECU would be programmed any differently. If the new C63s has the GPF like the CLA45, it would adapt to less restrictions the same way as suggested by the Bogenshutz guy.

First step is to identify where that SOAB is hiding. Did they put it in the downpipe? Inside the secondary cat? Where is it haha?
