Fitment & important exhaust notes

• Transmission: Automatic only
• Factory exhaust: Compatible with vehicles originally equipped with NPP or non-NPP exhaust
• Important: This is a non-NPP axle-back system. Vehicles originally equipped with NPP will no longer retain selectable exhaust modes, and factory valves/actuators must be handled per the installer’s preferred solution.
