If you have a set of dual-outlet Borla mufflers and would like to add NPP exhaust then you need to get these adapters. These pipes include valves and are intended to add the NPP (dual-mode option) to a system that did not come with the necessary valves (11920, 11921). They can only be used with mufflers that have dual tips exiting the mufflers. Wiring is not included. They are not intended to add NPP to a vehicle that was not originally equipped
