If I add your kit, the exhaust still opens at a pre-set rpm like factory, correct? What RPM is this?

Correct, If the driver accelerates hard the valves will open at 2,800 rpm as long as the driver is above 80% throttle. Between 30% and 80% throttle the exhaust will open during acceleration at 3,500 rpm.

So when you use the remote, is ON always open and OFF default / factory operation mode? Or is there a totally off function that leaves them closed all the time?

What signal does the NPP in a box use to know when to open the valves via rpm?

With the NPP it is either 100% open or 100% closed

With the M2W it is either 100% or when closed it reverts to the factory setting

I finally got a chance this weekend (12/6/2014) to install the NPP in a box. All went well until I tried using the remote. It will not open or close using the remote. I checked the remote batteries 12.4 volts. I opened the box changed the red for white wires and the valves open and close. The remotes are not working and or the receiver/transmitter box. I sent you an email I hope you get back to me soon.

Please let me know what to do now.

Use what the PRO's use - Thanks to LG, ECS, Vette Doctors, Corvettes of Westchester, Corvettes of Houston and the many other Chevy Dealers for choosing this system to install in their customers cars, they demand the best and so should you. If you have any concerns or questions about the quality or ease of installation feel free to call them an see why NPP in a box is their choice.

VetteDoctors (Carmen) “Your NPP system is the best on the market. Very easy to install & your service is second to none.”
East Cost Supercharging(Chris) “We installed one last week and I must say the product was very well put together and a smooth install.. Thanks”
Corvettes of Westchester(Chuck) "I can't say enough about the NPP in a box PRODUCT! The kits are first rate! EVERYONE wants them! PRICE IS AWESOME!
SHIPPING IS ALMOST INSTANT! What more could you want!?!?"



1. The vacuum source off the motor had to be extremely simple to get. No removing coil packs or trying to access the back of the plenum and break off the unused vacuum line. It does not use the booster supply, so no worry there. On the LS2 /LS3 it will take you less than 5 min to install the vacuum tap (no tools needed) our innovation, approved and tested at vette doctors.

2. Want innovations, I did not just copy the GM system. I developed a 100% new system where the control is no bigger than a box of Twinkies. All parts are enclosed in the box (no separate controller to install) and will be located 100% in the car (rear storage hatch) with both the wireless control and the vacuum controls safely housed inside so you have no weather issues. The power supply is in a heavy double shielded cable, 5 min no tools and nothing to pop off or remove.

3. Cost is $179 and will include everything needed, you just supply the exhaust. You just install the vacuum tap, run the provided vacuum line from the motor to the rear, run and install the provided power harness, install the control box and hook up the vacuum lines. The whole system will draw less than ½ amp, have zero drain with the car off and start either open or close. It is not designed to work with the car2u visor yet but will have Mild2Wild built in or ask about a custom unit with a foot switch.

4.Designed to work with both the B&B and the GM NPP system that are installed in a retrofit configuration.


like to see what your getting? - here it is


Here is the complete process

NPP in a box, a set of NPP mufflers will give you an incredibly easy way to have just the sound you want, when you want, if you have a pre-2008 C6. In my case, throw in a set of LG headers, and you have rolling thunder at the flick of a switch. The combo of the headers and the NPP in Wild gives you AMAZING sound and “HEY, LOOK AT ME!!!” volume…the tonality and sound is that of a NASCAR stock car at WOT outside the car, yet quieter and less drone inside the car than the GH* exhaust I was so fond of. The install is very straight forward, easier with a lift, but as has shown, you can do it on jack stands. Here are some pics and descriptions of the step by step process; you will receive complete illustrated instructions with your purchase.

NPP Mufflers waiting for Install




Factory Exhaust Removed



Drilling a ¼” hole in the rear well



Run the Vacuum Tube though the hole



Run the Vacuum tubes through existing frame locations







After dropping the rear sway bar, snake the NPP mufflers up and over





Attach the pipes to the mufflers



Connect the vacuum hoses to the NPP mufflers




Make sure your muffler pipes are straight and level



Muffler hardware done and vacuum tubing run



Connect power cable to the Seat Heater Fuse




And of course, a quick hit with our Polishing kit







That's all there is to it.....All that's left is to go out there and have a blast with your new found customized sound.
