Exhaust exiting one side at startup

Is this normal? Shouldn't the exhaust come out of both sides during a cold startup?

If you put your hand on both sides of the exhaust does one feel completely different than the other?

Huh, never seen that before. Mine definitely comes out both. I wonder if one of your AFM valves is stuck.

Nothing comes out of the driver's side exhaust on startup. This is only in Touring mode. The dealer, of course, says there is nothing wrong.

I'd find a different dealer because that it not how it should work. It is strange that it only does it in Touring mode though.

Did you look into the driver side exhaust to see if the valve is stuck?

If your in touring mode in that vid, the car sounds a little louder than it should be. It sounds like the npp valve on the driver side is working, but on the passenger side its not (stuck open).

Outside pipes meant valve open (loud). Inside pipes means valves closed (tour), at low idle. It would seem if you are in tour mode and low idle both inside pipes should have flow.
