Corvette C6 NPP In a Box Retro Fit System...
Do you have a C6 that does not have the NPP/Multi mode exhaust option?
If you can get your hands on the mufflers (used or new, Z06 or Coupe Mufflers with the NPP options) you can add the Multi mode exhaust system to your Corvette C6 without the huge expense of a dealer installation.
The is the official "NPP in a Box Kit" kit and it contains everything you need (except the mufflers) to do the conversion.
Ready to order and ship within 24 hrs...
More info and installation instructions here...

Just did this yesterday and this is probably one of the best mods I have done so far. I have H/C/I and the NPP in a box saved me!! I was going insane with the Borlas haha.

This does not have a vacuum pump. It uses the vacuum off the intake. This does include a vacuum controller that applies or removes vacuum from the mufflers though. It is a retrofit kit for cars that do not already have the vacuum controller. The M2W by itself does not control vacuum at all. The M2W just allows you to switch a car that is already equipped with a full NPP system. HTH.

This kit retro fits a car that does not have NPP from the factory. Gives you everything you need except the mufflers.

Bottom line, this is the kit needed for someone who does not have NPP installed from the factory. If you get the NPP mufflers and then this kit you can convert your car to the NPP setup.
Sent you an email about the covers....

With Respect;
Can someone tell me why a Vette owner would want to retrofit a NPP system onto a non-NPP car?
This question is from a soon-to-be former LS1 fbody owner. I have LT headers and I just don't understand the whole noise issue.
After all, with judicious selection of the right muffler system, you can have reasonable street decibels and low restriction. As you climb rpms, yeah, the noise gets louder, but that's the effect of high rpm operation.
Is this decibel issue a fbody/musclecar vs. sportscar perception issue? Are the "older" (j/k!)
sportscar/Vette guys more critical about day-2-day operating exhaust noise than the average fbody owner?
Just wondering!
