C6 Exhaust - NPP
Just got a C6 vert and looking to upgrade from stock exhaust. Looking to possibly add the Z06 NPP exhaust with "mild to wild" function. Any pros or cons? My wife is not a big fan of loud exhaust systems so looking for something that's adjustable. Thoughts?

Took my NPP off and put on Magnaflows. Yeah a lot noisier but also 30 lbs less weight. I have the mild to wild key fob thing for sale if you go that route.

I have 2011 GS with NPP
I have a 2011 GS Coupe with the NPP option. I put on the toggle switch from Mid America Corvette and I really like it. The NPP is plenty noisy when open and I can quiet it down whenever I like with the switch. Really the best of both worlds as the drone with the exhaust open gets tiresome at moderate speeds around town or on the highway. Best of all my wife does not complain when she is with me!

The MY of your C6 makes a difference also, since the pipes are not all the same for all years for the NPP. '08 NPP is a bolt-on to '05-'08, but '09 and up NPP only bolt on to '09 and up.
You can weld any year Z06 muffler or NPP muffler on to your current C6 over-the-axle pipe.
Knowing more about what you have and how you choose to approach the result is required information.

There's a difference between the Z06 and NPP exhaust systems, so don't confuse the two by saying Z06 NPP.

You can trade mufflers with no problems, but he will need to block off the vacuum connection, preferably at the intake manifold. You will need to make or purchase a controller, unless you never intend to close the flaps.
