NPP Exhaust Valves Not Opening

I received my car this weekend and have noticed my exhaust didn't change tones during the switching of modes on the center console ****. So I had my brother switch the modes while I watched the exhaust valves and they never open.

Do the valves stay closed until a certain amount of valves? I'm only at 50 miles now.

Put it in track mode and you should hear a difference.

If you still can't tell, pull the NPP fuse. It's #42 in both 15's and 16's.
(#41 in 14')

With the engine idling Go to settings then engine sound management and pick sport or track mode on the informant screen. Valves should open up at idle and stay open.
