Took delivery of my 2022 M850 GC back in November. Still waiting on some mods to come in but in the meantime, thought I'd see what kind of sound I could get with a resonator delete.
Haven't seen anyone else on here attempt it yet except for the M8. Found a couple of videos on YT but they were based in Europe and done on the '19 and '20 models. Most know the sound really got neutered for the later models.
I'm happy with the results. Some might not be since it definitely does not take the place of a full exhaust system like Fi but honestly wasn't looking for something crazy expensive on a lease for just a little bit more sound.
I'm happy with it for what it is. FYI videos could definitely be better quality, was in a hurry when shot them and won't be able to re-shoot for a while. For some reason comfort mode on startup and idling sounds better in the clip than IRL but nonetheless can definitely notice a difference over stock. Should have let it idle more in sports mode to get the full sound but oh well. Anyway, here's some videos for anyone who's been on the fence about it. Replaced with straight pipes btw.
