    Stock exhaust valve

    Hey everyone...I'm new here and Just leased a 2021 540i M Sport. Not doing anything crazy to the car because of that. Minor things like window tint. But I do want to have the exhaust valve open at all times. Anyone know the trick to get it stay open?

    Search over on Bimmerfest...there are several threads that describe the process for putting the car in sport mode and pulling a fuse in the trunk to lock it open
