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
NPP in a BOX (with optional selectable start up mode - lets you select if it starts loud
or quite) $199.99
Optional LS2 / LS3 E-Z Vacuum tap $15.99 (allows for a much easier vacuum tap from the front
of the intake, can only be purchased with npp in a box, not sold separately)
