Sorry if I got this wrong....but the op was asking regarding the mild to wild switch would work and then mentioned he did not have NPP. Would not the answer be it will not work unless you installed a NPP system? The Mild to Wild switch is not an exhaust system but a way to manually control a NPP exhaust.
Believe your bang on..Thanks
I don't mean to confuse, and I apologize for my previous comment - just being funny because my car is loud as EFF with Corsa Extreme and no NPP or otherwise.
Anyway Tim, the answer to your question is twofold:
Yes, you can have a Mild to Wild setup installed on your 06 C6, but no, it is not just as simple as buying a remote or a switchbox to make it work. Your car does not have the factory hardware to do this, but you certainly can add it.
First of all, Mild to Wild is an aftermarket brand (not Chevrolet) that controls electronically actuated valves to direct your exhaust flow. I will try to explain this simply and y'all will forgive me for being crude and technically inaccurate, but in the interest of establishing a basic understanding, I'm going to stick to my KISS (Keep It Simple, Stupid) principle.
At heart, we are all still teenagers and want our car to be loud (like straight-pipes or 'bottles'), but in reality we are all old, married, and live in neighborhoods where we don't want to wake our neighbors, the kids, or our wives when we come home after a long night of cruising. We WANT loud, but we sometimes NEED quiet. So what do we do?
For years now, we have had these nifty things called 'cutouts'. On classic hot rods, it is a simple Y at the end of each header (exhaust manifold) with a bolted cap and a gasket inside. With the cap bolted on, the exhaust goes through the pipes and the mufflers, and makes a subdued sound. With the cap unbolted off, some of the exhaust can come out right at the end of the header, and it is pretty much as loud as an engine can get. Although I do know plenty of people who carry a ratchet and socket to take these caps off and put them back on again, it is a not only a pain in the ass, but those pipes get
really hot. I mean permanent scars kinda hot, and Corvettes are not exactly easy to get under (or into) to work with those caps.
Many years of evolution later, we had electric cutouts, which is simply a motorized butterfly valve at the aforementioned Y that will determine whether the exhaust goes out of the cutout (loud) or through the pipes and mufflers (less loud).
The Corvette NPP system is very similar, except that the Y is not located at the header, it is located at the mufflers. The same principle of the butterfly valve still applies. When being 'quiet', the exhaust is directed through the main chambers of the muffler to reduce the sound. When being 'loud' the exhaust is directed around the chambers to the open pipes which makes the unmuffled noise. Although all C6 (&C7) Corvettes have four exhaust tips, the NPP only uses two at a time. Two quiet ones, or two loud ones. [This also helps to explain why you NPP guys have two dirty pipes, and two clean ones].
You can certainly purchase aftermarket mufflers with the electric valves to do exactly the same thing on your 06. The Mild to Wild switch is simply an electric cutout that is controlled with a remote so that you can decide when it should be loud, and when it should be quiet.
The factory NPP is designed such that if you are at full throttle, or above 3500rpm, the exhaust should be 'loud'. The Mild to Wild lets you decide all the time, whether at idle, part throttle, or full throttle.
Or you could just buy a Corsa Sport axle-back. It sounds better under throttle than any of the stock exhaust (NPP or not), and is quiet when you are being easy on the throttle. Why did I type all of this? Corsa Sport axle-back. Just do that.
