New C43
When I asked my dealer about that, they send me an answer from the mechs dept. talking about the differences (mainly 7Gvs.9G) between both C450 and C43 models, which didn't convinced me at all, I'm not an expert, but I can see an excuse from miles away; they just don't have a clue. I'm being a good boy with my running in, so I can't tell about the sounds over those 4500rpm's, but when I've approached that edge, I can ear some, very subtile, reminders to that metallic popop, but nothing like the C450 I tested.
It's known that some MB guys are MBWorld forum members, so it would be wonderful if any could bring us some light (or pops or crackles) here.

I even wrote it in an earlier thread that I wouldn't be surprised if c43<c450<c43 performance exhaust. (source: https://mbworld.org/forums/c-class-w...ml#post6839831 )
Hope there is just something wrong or that it will start cracking with a few more miles on the clock.

It also says that some of the driving and safety systems adjust automatically during the break-in period. It's a long shot, but maybe that affects the crackle&pop from the exhaust.

Also, the crackles and pops were very pronounced in the early stages of the car. I would say the crackles and pops do diminish and become more unpredictable and less pronounced after 2-3000miles. Which was the reason why I upgraded to the AWE Tuning Touring dual exhausts.
The car is great to drive, smooth, quick and fun. It can be very comfortable for cruising or great to play around with in sports+, like 2 different cars! I am relieved that I really like my choose of colours - selenite grey and saddle brown.
My only disappointment, and was partially expecting this, there is no pop and crackle from the exhaust, without the performance exhaust. Here in Australia you can't order the performance exhaust separately from the performance seats. I found the performance seats really uncomfortable for me, so had to go standard (which I am loving!), but had to sacrifice the performance exhaust. Forums I read were suggesting the standard exhaust should still pop and crackle, but unfortunately it doesn't, although it is nice and loud. May look at aftermarket options...
Also interesting to note is that the dealer said there is no break in period required! They said the C63 requires break in, being a hand made engine, but not the C43, can give it a whack straight away! So I did!
Overall, so happy with it and I am sure you will be too!

Still running her in, so not using the full potential yet, but played a little with the different driving modes

She's been fully de-badged and we're having the roof vinyl wrapped next week gloss black to complete the line across the top of the car.
Also fitted some front arch guards in satin black and a new Blackvue DR650S 2CH camera system.
These are the arch guards, the website shows they are for the A, B and CLA class, but they also fit the new C class perfectly as well.

Where did you hear that? Last communication I got from my SA was that it had passed certification and was on a train from Halifax to Edmonton with a dealer ETA of Oct 16th... this was on Sept 27th.
Hopefully no lengthy delays - should be a quick trip from Baltimore to Central OH.
I am currently debating doing Xpel but almost set on doing a Modesta coating. Doing both is kind of expensive and comes out to be 10% price of the car so not sure if its worth it really.

when you get the car, new I would NOT "Drive it like I stole it"
I know that sounds fun and cool, but what is the downside to waiting 1000 miles, varying the rpm, not BANGING on the car when it hasn't been broken in, seated, etc..
The manual says, don't exceed xyz, S+, high RPM, high MPH.
Years ago, I asked the engineers and product managers what the deal was and they said, "break her in nicely and she'll provide years of joy and trouble free service"
It sounds more interesting in the original German.
(disclaimer.. I worked for DB for seven years in the 90's and drove everything they had hard and fast)
