In the C6 the NPP option employed simple vacuum actuators to open/close the butterflies. It sent no feedback to the computer defining if it was working so no CEL trips. In addition, the fuse panel was behind the carpet in the passenger footwell. Easy to access and the remote relay was close to the transmitter and away from heat.
It was also very easy to add a simple ~$5 toggle switch to disconnect the fuse when desired and route the wires to the console. That is what I did. Put the simple switch in the front cup holder. Unlike a remote relay or my garage door opener, the switch was positive and instant!
From my observation over 3 1/2 years, looks like Mild-To-Wild provides the proper remote relay that works in the engine compartment and wiring that fits in the front fuse panel. Lots of early efforts that didn't work before some forum members found a solution. Most disassembled the remote relay to fit parts inside the fuse panel.

Well I helped my buddy put one in his car today and guess what? It doesn't work. Apparently it does nothing in Sport or Track and only on Touring did it seem to work to him, not me. We set the settings on the car and did everything exactly as instructed and heard nothing. It is on a 2014 but even so, maybe it's a defective one. But I thought it was so you could open the flaps in Sport & Track and they'd stay open unless you turned them off? If I'm mistaken please correct me and tell me the way it really works.

Just a "Heads Up" for all you guys looking to get a
Mild to Wild Switch. They work fine on '15-17 Corvettes, but on a 2014 it only works in Touring mode, not in Sport or Track. The reason? The '15's on up have more electronic options that the owner can change and the switch works fine on those. Guess from now on we'll be known as "The Quiet Ones."

"On the 2014 GM gave the car a limited exhaust options menu. In touring mode the car starts closed, so mild2wild will open and keep open the exhaust. In sport mode the exhaust starts open so mild2wild can’t close it, but it does keep it open 100% instead of closing under select conditions.
In the 2015-2017 model years they added stealth mode to the exhaust settings which keeps the exhaust closed 100%. In this case mild2wild works to keep the exhaust open 100% or lets it close to stealth mode giving you full independent control."

I don't know for sure, but I'd guess the major difference is the C7 version is wirelessly switchable, either with the supplied fobs or by programming to Homelink, because the fuse controlling NPP is in the engine bay fusebox. Since the C6 fuse was located under the passenger-side dash fusebox, it was a simple wired switch.
I suppose one could modify the C6 kit and run a wire through the firewall if they already have one. OTOH, why go to all that trouble to save $70?

No, even set on Track mode, the valves are not open all the time for noise regulation reasons.
The only way to keep the NPP valves open all the time is to remove the fuse, which is what a lot of folks have done. Problem with that is, you may want to keep the option of quieting the car down without pulling over, and reinstalling the fuse.
The M2W does the same thing as pulling the fuse manually and putting it back in.

That's not true for Z06 owners. GS and Stringray owners have that tip-in point where the flaps close below a certain RPM. It drove me crazy with my old Stingray. The Z06 exhaust stays open all the time in Track mode. I feel bad for Z06 owners who buy this product, because they don't need it.

(There are pictures included.)
It works great but unlike another "respondee", mine always goes back to off when the Vette is shut down. I have to turn it back on every time I restart.
If someone knows how to reverse this, I am open to it.

The "tip-in" you mention occurred at 1700 rpm in my previous Z51. An interesting point, though, is that my 2016 Z06 also exhibits a similar "tip-in". With the exhaust mode set to Track, it only occurs in 5th gear and at 1400 rpm -- valves closed and quiet below 1400 rpm, valves open above 1400 rpm. I'll guess that this allows passing noise regulations, as I think the noise passby testing has a starting speed of 30 mph -- 1400 rpm in the Z06 yields 40 mph.

It sounds like maybe you're experiencing a shift into V4 mode, because I have not heard any such tip-in on my Z06 (also a 2016). Is yours an A8 or M7? If M7 it would have to be in Eco mode in order to go into V4 mode, but with an A8 it could be in Tour (maybe also in Sport?).

On the C6 there were two types of installations, one that was described as "Zero Battery Drain" and the second that had a very slight battery drain. Does this unit for the C7 have the slight battery drain or is it a "Zero Battery Drain" installation?
