Why CORSA Xtreme with NPP
This system pairs CORSA’s patented Reflective Sound Cancellation® (RSC®) technology with factory NPP valve control. In Touring mode, exhaust volume is reduced for street driving. In Sport or Track mode, the valves open to unleash a sharp, race-inspired exhaust note — without the low-frequency drone common in other systems.
