Question C63s Coupe Pre-Facelift Rear Diffuser Won't Fit on my Facelift Bumper

Hello, I have a 2019 C63s Coupe. I ordered the Pre-Facelift Carbon Fiber diffuser, the part # is: A-205-885-4105. I wanted to install this pre-facelift diffuser on my facelifted 2019 C63s Coupe. From what I understood, it should fit right on, as the prefacelift and facelift coupe bumpers are the same, correct? I did my research beforehand and was pretty sure it would retrofit right on. I took it to the mechanic today and he told me that it did not fit at all, and there were gaps and the clips were facing opposite, or something like that.

Did I make a mistake with the part numbers? Is this the correct part? I wanted the pre-facelifted CF diffuser, and I'm pretty sure this is the right part. If it is the right part, does that mean that the rear bumpers aren't identical and there are some differences? Did I make a mistake with the parts, or is it simply that the part will not fit on my facelifted car?

If anyone has some insight on this, I'd appreciate it, I'm not too sure what to

No it's not going to fit. Why didn't you get the facelift carbon fiber diffuser for your facelift car? Strange idea

Exhaust tips on the facelift are also larger, it will not fit.

I have a PFL Diffuser on my 2021 because I have an Akrapovic exhaust and the tips don't fit on the FL diffuser. My shop did not have any issues installing the PFL diffuser after a few minor adjustments!

Nice. I'm considering one as well. Exactly which one is it? Their website is extremely confusing. Did you get it from a distributor?

Yeah, it is weird- you have to order the link pipe set and the exhaust together. I got mine from Turn 14 (distributor)

Hello, the reason is because I wanted to install the PSM Dynamics diffuser on my facelifted car. This diffuser bolts on to the PFL diffuser as an attachment. Therefore I got the PFL diffuser and I assumed it would fit since the PFL and FL did not have a bumper change, or so I thought. I guess Ill have to get the FL diffuser and try to fit the PSM Dynamics onto it, somehow.
