*NPP in A Box will turn any C6 into a Bi-mode exhaust equipted car, you provide the mufflers, I provide the rest.
*If you already have NPP (bi-mode) mufflers from the factory, just purchase Mild2Wild.
*We now have the E-Z Tap for both LS2 and LS3 motors. This provides a much easier way to tap the vacuum. 5 min and your done as compared with trying to access the back of the intake (almost imposable) and saves hours of frustration.
