OPF Filter - sound question

Do any c63 models in the US have the OPF filter?

If not do 18,19 models still sound better than 20 onwards?

No OPF on US spec models. Better is subjective. The FL 2019+ sounds different and to my ears better, because I was never a fan of the artificial pops & bangs.

2020 C63s Coupe

No OPF on US model. Original pre-facelift model sounded louder, but MB eventually muted the sound after some software update.
So both old and new models are not too loud unless you modify software/hardware.

After dealer software update it sounded quieter but after some time the sound came back. PFL sounds much louder and has nice pops and bangs. The difference in sound between FL and PFL is night and day. A lot FL guys sold their FL to get PFL because of the sound.
MB’s launch FL sounded good but after arriving at dealerships the sound was not the same as Launch FL.
I got PFL with Renntech exhaust module and it’s perfect!
