Good evening everyone *(if was when I wrote this post)* -- please excuse my ignorance here, and my newbiness but what exactly is mild-to-wild, a C6 I am considering purchasing has this and key-fob along with it with the pushbuttons. I know it has to do with the exhaust -- perhaps changes the level of noise from the car itself, but how does it work? what is it exactly etc...?

I have to assume this is an ADD-on product to a C6 -- aftermarket? or is this actually OEM option?

Thank you.

Regards,
Charles

It’s aftermarket brand named “Mild to Wild”. And yes works exactly like the OEM NPP system on the C7 Corvettes.
Very popular with guys who have C6s as they do not have the option to select an exhaust mode on their corvette. On C6 OEM It is an automatic system that opens up the exhaust at higher RPM. (Guys I’m not sure about C5 or C4s. Some one can let us know about what is on those car OEM)
Most times it’s controlled with a small remote and I have recently learned some guys put it on a switch somewhere in the car.
I had it on my 13 Z06. It’s a good system.

Here’s a video

 
I had it on my Camaro and I put it on my C7 as well. It does work off a remote but you don't have to add a switch like Derek suggest some do above if you have the 3 homelink buttons in your car. You can program the two buttons on the remote, on and off, to two of the home link buttons very easily. It works like a charm.

Now, before someone asks yes my vette has the options to control the exhaust within the system. But you have to go through various menus on the screen to find and change it. I take my car to work on nice summer days and I leave very early. I keep the car on stealth mode leaving my neighborhood so I don't piss off my neighbours and then once I get out on the main drag I reach up and push the button on the homelinke and voila..fully open NPP exhaust.
 
Good morning everyone -- thank you for the information, but sorry I am still completely lost. I watched the video, the gentlemen in the video noted something called the NPP -- which also made it quite and then loud depending on how he pushed the gas. Ok I am going to assume this device overrides the computer control of the exhaust so you can force "stay quite" mode and then turn it off --so the computer then opens the exhaust for the roar.

This way this device is not really a way to make it louder it is a device to make quieter -- meaning essentially it permits you to push the gas which would normally engage high roar, to prevent this from happening then you switch it off, as the video is showing and we are back to technically normal roar.

Am I correct here? or I am completely lost?

You aren't wrong Charles. What it does is over ride the NPP exahaust controls essentially to either have it as open and loud as the exhaust can be or as closed and quiet as it can be. The NPP exhaust is the type of exhaust which is on the C7's and I thought the C6's as well but maybe not on all model of C6s perhaps?? If your C6 does not have the Chevy NPP exhaust option then the M2W will not do anything for you.

Edit: It looks like the NPP exhaust was added to the 2008 and newer models of the C6 according to the wiki
C6 wiki link
 
Hello, ok this explains a lot. Could a C6 from 2008 -- not have NPP -- is this possible to be purchased? I mean if I found two C6's could one potentially been manufactured without NPP -- and this is an option so that someone could use M2W -- and if the 2008 did not have NPP - -assuming one could buy one this way originally then M2W would be meaningless?

I am understanding correctly?

Google is your friend 😂
That’s where we learned half this crap

Ya that’s cool about the homelink buttons. I just learned that tonight watching another video... damn YouTube... once you get started.
Now you confirmed it. 👍👍
 
I know beans about this, so explain to me how is the exhaust designed to open up ? Don't tell me about remote control buttons. Is there a seperate exhaust pipe ? , split pipes with one by passing the muffler going straight through open and closed by a butterfly ? I wanna know what is under the car ? In the old days a guy just took off the header plugs , this just sounds like same type of deal only fancy way of doing it.

I'm late to this, and Pep's video shows the difference in sound and explains it a bit, but doesn't really get into it. I think I've delved into this in another thread, but whatever, this is the Interballs.

Essentially, the pipe comes into the muffler and Y's through the canister. One side is baffled and quiet, the other is not exactly straight-pipe, but certainly much-less baffled. This is the one that has a butterfly. When it is closed, the back-pressure will cause the exhaust to go out the baffled and more quiet side. When it is open, it will flow through both sides, although one is much better than the other, and does make a really neat noise from that perspective. Both muffled and open at the same time - It really is a cool sound.

The factory system is vacuum-actuated on the early systems (I think C7's are electronic and based on rpms and throttle position), and the Mild-to-Wild system is electronic, based on what you want and when you want. With the M2W, you can have it open at idle, or all the damn time if you want to, whereas the stock NPP system is based on how hard you are on the throttle.

It is quite simply the next step of evolution in electric cutouts, while being able to maintain emissions. Classic aftermarket options being implemented into modern engineering and yet still meets all EPA and other regulations.
 
thanks Jeremiad, yeah it is not complicated how it works , I just didn't know what they were doing or how. Back then the cutouts were cable controlled so you did it manually directing the exhaust flow through the mufflers or through a straight pipe. I never heard these modern day jobs , only on the monitor , but I don't like the funny raspy sound that these motors make today. I still say nothing beats the sound of a carb fed V8 with dual glass packs.
