Dual Mode Exhaust
I have a 2015 ls. How do you know if you have the dual mode exhaust, or do they all have them?

Do you have the quad or duel tips. If dual then you don’t have NPP. if quad, look inside the end of the exhaust. I can’t remember which side, inner or outer but you will see the actuator valve if it’s NPP.
