For the EU M5 2020/2021 facelift owners: Has anybody tried the OPF delete modules yet?
As mentioned in other threads the new M5 LCI sounds like a 4cl in idle after the cold start. It's really sad and I miss the emotion that I had with my previous m4.
With these OPF delete modules you should be able to remove the OPF part of the exhaust and it should give you a better sound. Risk is of course the warranty - but depending on how they modify I suppose I should be able to re-attach the OPF part of the exhaust (what do you think?)

Hopefully somebody already has experience with this? An alternative is Manhart but they charge double:
