These pipes are intended to add the NPP (dual mode option) to a Borla® system that did not come with the necessary valves (PN 11920 and 11921). They can only be used with mufflers that have dual tips exiting the mufflers. Wiring and actuators are not included. They are not intended to add NPP to a vehicle that was not originally equipped.
