NPP in A Box will turn any 2005-2007 LS2 or 2008-2013 LS3 C6 Corvette into a Bi-mode exhaust equipped car but, YOU MUST provide the mufflers.... we provide the rest

 
If your Corvette came with the NPP (bi-mode) mufflers from the factory, just purchase  the normal Mild2Wild in our other auctions
 
We now include the E-Z Tap for both LS2 and LS3 (For Corvettes Only) motors. This provides a much easier way to tap the vacuum. 5 min's and you're 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 OUR 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.

Please let us know if you need this kit for a LS2 or LS3 motor. We can not ship unless you tell us this info
Even with our kit sold here YOU will have to buy the NPP mufflers yourself in order to make this work. 

 

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.
  • All Parts Are Included (except the Mufflers) which means you get All tubing, fittings, and controllers.
  • Please let us know if you need this kit for a LS2 or LS3 motor. We can not ship unless you tell us this info 
  • 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.
