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.

So you can install and set to closed when startup (so not to wake the little one up in the morning.) after that the remote can open them as wanted (but cannot be done from the visor remote?

Also when hitting approx 3500 rpms will this let them open or at wot?

Thanks just got my bi modes and determining the best way to go on the install.

Top Flight Reproductions

Correct, you can set it to start up open or closed and then control it from the remotes unless you car was built prior to 10/2006 and then you can program it we can built it with an foot switch (like the old dimmer switch) instead of the wireless remotes. NPP in a box gives you either open or closed functionally, once you install it you will see that is what works best. The 3500 rpm feature is what comes from the factory and what everyone overrides it, so NPP in a box will not open at a set RPM.

How does this allow for open/close on start up?

Top Flight Reproductions

it's in the instructions, last page, you switch the connector in the box

Top Flight Reproductions

Are these in stock, ready to go? I got a fever and the only thing that'll cure it is more vacuum actuated muffler valves

Can one use the "old school" dead pedal switch with the NPP in a Box?

Top Flight Reproductions

Yes in stock and yes NPP can be used with the Old School

This is a great product... I love the NPP Retrofit I did to my 2007 Coupe with Z51.... Straight ahead and great results. I installed a switch in my Tombstone to control the NPP (keep the keys/remote in my pocket)... See my thread about the retrofit here.

Thanks again Peter!!

Thank you Francis

Tell me I'm wrong, but aren't the NPP mufflers about $750.00 ea?

Top Flight Reproductions

Not sure why you're asking, I would suggest looking in the parts for sale section

I just wanted to say that these are stand up guys. I had a small problem with my NPP that I recently installed. It was handled fast, quick and taken care of the same day.

Thanks Steve, we appreciate it
