Full exhaust options for facelifted 2019 C63S
Or has anyone tried removing the secondary cats yet to see if it restores some of the pre-face lift sound?
Another disgruntled '19 C63S owner here, as a former E92 M3 owner - one of the main reasons I got the C63S over the M4 was the sound.. very disappointed in how muted it is. I don't think MB is going to fix it, I'm at the point of just doing the secondary cat delete if no full exhausts are out.
I'm debating secondary cats, I've added an ASR module so it's a bit louder lower down at least - highly recommended.
Next step, like you said, is finding its physical location and understanding how to remove it without triggering any codes or other bad behavior.

I'm a fan of AWE exhausts, I don't think they've released one for the facelifted model yet (I could be wrong?)

While I was doing some extreme deep-dive research into the issue, I found a comment on social media made by someone in the AMG marketing department about how '19 C43s have the petrol particulate filter as a new part. I currently have an '18 C43 and drove a '19 C43 a few weeks ago. It's definitely a less raucous soundtrack than my '18.
Point being, it seems that filter has infiltrated US-spec LCI C43s.
However, I still believe it is LOUDER than the pre
but does not POP and CRACKLE as before, just
under different conditions.

Superswiss made that point which I believe is correct.
AMG seem to have reprogrammed the ECU to adapt to your driving
style a lot more than the pre face lift.
So so now selecting sport + or race will not release the full characteristics of those
drive programmes. It will then react to your driving style within the chosen program.
My pre facelift was very difficult to drive smoothly in sport+ in stop and go traffic.
It would lurch forward at the slightest dap of throttle.
The facelift has smoothened the otherwise rough edges of the C63, making it more capable
of putting down power a lot better and improving traction.
You are setting too much precedent on the option code. If Mercedes could make two different exhaust, they would have done two different tunes for Europe and NA as well, and NA cars would have had the pops and crackles. The reason NA cars are quiet tells you they did not bother to change anything. For some reason it is not showing up in the build code, but these cars sure do have the PF installed in them.
As long you don't alter the tune of the engine, and decat it, your powertrain warranty will be intact. Only exhaust warranty will be voided. Confirmed by the Mercedes field service manager Brent Prusse, not the dealership.
Your initial question was do I have the part. Answer was yes
