Product Description

NPP in A Box will turn any C6 Corvette into a Bi-mode exhaust equipped car, you provide the mufflers, we 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's and your done as compared with trying to access the back of the intake (almost impossible) and saves hours of frustration

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 (included).  All the parts needed are provided to allow you to tap engine vacuum to operate you mufflers (just like the OEM system).  No special tools needed and average install is 30min, very simple.


What makes NPP in a BOX your only choice

  • Very Low Operating Current = (less than 1/2 amp) generally systems like this take a few amps so NPP in a box will never / compromise your $50-80K car
  • Ease Of Installation = A 15 minute simple install, 8 page color picture instructions
  • Quality Of Components = Not only have I been working with the leaders in vacuum control, Each component (enclosure, components, wire and connectors) are the best you can use.

  • It will only work as on and off.  The computer in cars not delivered with NPP cannot be programmed to make the exhaust work as a factory one would making them open above 3,300 RPM.
