I think I did it with the car running to ensure they’re open. If you turn the car off, they may close again. I doubt if you turned the car off it S+, that when it started they would be open. At minimum it’d close them on start up again.
Just try with the vehicle running. This will keep them open permanently. It’s important to remember that even when in S+, they’re not just open all the time. They open and close based on revs. So this is the only way to keep them open. |

Still waiting on BMW San Diego. They did acknowledge that the Dinan muffler is the problem. I was told that there is another fitment issues brought up from the East Coast, so Dinan is addressing it and manufacturing the mufflers...

I was going to have it done but it's too loud for wifey. So Dinan is the perfect compromise. |

Hey guys, I can't get my valve to open, I have tried everything.
It might be something wrong with it? Any ideas?

i found the same and plugged it back in. the gearing is higher in efficient mode and makes a low resonance in the cabin. in some instances it sounds like an exhaust leak more than a performance exhaust.
