Corvette C6 "NPP Exhaust In a Box"

Corvette Multi-Mode Exhaust Vacuum Retrofit System

NPP in A Box will turn any C6 into a Bi-mode exhaust equiped car, you provide the mufflers, I provide the rest. Comes with selectable start up mode - lets you select if your Corvette starts loud or quiet.

If you already have NPP (bi-mode) mufflers from the factory, just purchase Mild2Wild switch and you are good to go.

If you do not have the factory installed NPP Exhaust system, get the mufflers and our "NPP in a Box kit" and you will have everything you need to convert your car for a fraction of what your local dealerhsip will charge you. Just install the NPP mufflers from GM add NPP IN A BOX and you will have a fully functional NPP system that will use our Mild2Wild Swtich (included).
