NPP System
Anyone have an idea as to what it would cost to have the NPP system installed as an add on? I love my new (to me) 2010 GS, the only disappointment is not having the NPP. I actually pulled the fuse to open the baffles only to discover there were none. I thought the NPP was standard. That's what I get for assuming I guess.

NPP as an option cost $1,195, adds 6hp and sounds awesome. Look here....

You can check GM for new prices... more than a dedicated system like Corsa or Borla. I think I'm just going to get the Corsa Sport or Borla S Type II. Those systems have no drone.
Switching back and forth from loud to quiet seems cool but that would get old after a while for me. For me a dedicated not too loud, not too quiet system seems ideal.

You can figure on $600-$800 for the used mufflers (2009 and up should bolt right up) and then you'll need some sort of NPP in a Box system (controller, wires and such) for another $100-$300.
You'll need to make sure that the mufflers are NPP and not Z06 take offs as the Z06 mufflers are not as loud and they won't fit without some extra work (though some guys will modify the Z06 mufflers for extra sound).
Depending on how handy you are you can do the install (bolting up the mufflers, running / hooking up the wires, running / hooking up the vacuum lines) yourself on jack stands or pay someone with a lift to do it. It's not that hard if you are handy and have the right tools.

I just switched to just the z06 mufflers with muffler mod/mild to wild switch to a full z06 exhaust , manifolds cats x pipe and mufflers... cost me around 250 for the z06 set up, mufflers were all ready on the car, and muffler mod was 150.00 at my muffler shop....
When on the freeway hit the switch and its nice and quiet... always open around town.
the 3in setup is awesome.... even feel a little extra in the seat of the pants dyno....

Why would I want to knock one of the most popular systems for the car? The OP seems new to the c6 so I was just trying to present a balanced summation from what I'd gleaned from reading many threads on the system over the years.

My '08 vert did not come with NPP. I found a used set at Corvettes of Dallas and drove down on my birthday and had them installed along with the controller and a great looking exhaust plate enhancer. The entire bill was just under $1,100.
It was well worth it! I will not have another vette without NPP. I love the sound and as others have stated, I never had a problem with drone. I left mine open all of the time.

I can see where a 'vert may not have drone. However, for those that have a coupe, at low rpms with the flaps open there's drone. Whether or not it's objectionable is a matter of preference and tolerance (for me it depends how long I'll be stuck in that rpm range). To say drone is not there is 
: and you need to get your hearing checked.
