2018 C63s coupe OPF ?

[SatinGrey]

Hi all.

I need some assistance I’m trying to find out if my 2018 C63s coupe is fitted with the OPF I know it came in around June 2018 but how would I find out if I have it fitted to mine ?

Thanks

Option 598 on data card apparently?

The difference in exhaust sound should be quite noticeable.
