I have M5cs every time I start the car I received the below message, any idea what kind of update is this. Will it effect the sound or emission?

Also my car has opf so zero pops how may I increase the sound I think if I go catless the sound still not going to be huge since I have the opfs. What are you suggestions

My suggestion is to update your software. That’s well over a year old it seems. The M5 CS is much more muted than than it’s brethren but you could delete OPF, resonators, and secondary cats to get ore sound.

If I delete it I will get pops or this is related to Software ?
