Think these are worth it? The dahler one seems pretty good

Hard to find exhausts for the 230i so hoping one of these would be good for stock sound inside the cabin? Would this affect warranty?

Even though I have the MAD controller, I can't comment on brand superiority--save to say that many share the same basic design and, ultimately, do (basically) the same thing. Value is, kinda, a whole other topic.

Research: a few conversations that focus on your questions/concerns.

I'm extremely please with my SST valve controller for my 2024 M4. Works great and does help with better volume. I bought one for my wifes M240i that should be delivering to my dealership next week that I will install first thing.
