I have checked all the videos on youtube, no way sounds like the old cla45 AMG....
anyone have the actual car that can help to confirm?

I test drove one last night and when under load (driving versus sitting and reving) it sounds pretty darn good for a stock "no valve" exhaust. And the AMG Real Sound option brings in the actual outside exhaust sound into the cabin versus some fake exhaust sounds.

And this is coming from one who currently owns a C63S Coupe with Catless DP's. But they are two totally different cars. Sound different and drive totally different. I actually kind of like the way this 4 banger sounds especially on up shifts...reminds me of my 991 C4S (used to own) and it is just as fast.

Just my 2 cents!

The car doesn't sound great from the outside. The EU regs have really taken their toll however AMG Real Sound means the car sounds good from inside at least.

I've done almost 3k miles in mine and can confirm it does sound better once properly run in. You'll get consistent but natural sounding pops and bangs on overrun and gear changes when in race.

Whats the break in period? 1k miles?

Yes it's 1k miles. They'll be a sticker on your windscreen that gives you all the info.

Awesome, thanks, cant wait.

I've started pushing mine a bit more now with 800 KM (500 Miles) do you think its absolutely necessary to wait the full 1000 miles?
Have you managed to find any mods for it yet? I cant find anything!!

I wouldn't skip the run period. The engine is very high tolerance and there is also the rest of drivetrain to think about. I don't think Mercedes would advise taking it easy without good reason.

I reached 1k in two weeks so it's not long in the grand scheme of things.

I tested drove it today, sounds pretty amazing inside (from the speaker), From outside I think it is very muted.
Overall, feels like C43 with modified exhaust, very high pitch , not much bass.
Drive is very good, Gives me a lot of confidence cornering.
Probably going to keep my C63 and get rid of C450 for this one, anyone has any ideas what the 2022 model will be looks like?
