So, in theory, if I leave the car in "stealth" mode but open the exhaust with the M2W, when I close it, it reverts to "stealth" mode. Correct?
This device basically eliminates the 4th/5th gear 34-38 mph fly by closure. Correct?

When you operate the M2W device, you're producing the same effect as manually removing and reinstalling the fuse. With the fuse activated by the M2W device, the car functions with the OEM programming, which is changeable w/ the mode selector and setting menu.
For example if wanted your NPP car to be quiet or loud just by using the M2W device, in the settings menu you can program your exhaust to the Weather/Economy/Tour (quiet) setting for all modes. Then, you'd just use M2W to make it "loud" or "quiet."

Elmer, please update once you have installed to see if you feel it is louder at idle, or low rpm.
Have you received yours yet?
thanks,

OK....... so I must be missing something....
I went out, stood behind the car about 5 feet and use the remote start to start it up and listen to it as it currently is..... with the exhaust set to TRACK all the time.
I then went and removed fuse # 42 and repeated the exercise...... Sounds identical to me. I can't tell ANY difference. Folks were saying that even with the exhaust sound management setting set to TRACK, it still wasn't opening up the valves 100% of the way at idle, or low RPM's. They went on to say that with the fuse #42 pulled out, or using a Mild to Wild it would open the valves 100% of the way and sound louder at idle and low RPM.
I can't tell ANY difference. What am I missing???
Thanks

Here is an idle test after warmup. With decent speakers you should be able to hear the difference.

I ordered one but now I am wondering what's up...it should work the same for everyone, whether you pull the fuse or install the device. Silly question but everyone who is trying this NPP?

Let us know if you notice a difference. Like I said I pulled the fuse and drove in D and M and didn't notice anything. I might go with corsa xpipes since it's the cheapest.

YES, NPP exhaust. As stated above I have my settings for the exhaust to TRACK all the time, regardless of what driving mode. I had the car warmed up. Listened to it.
Then pulled fuse #42 did the same thing....... I can NOT tell any difference. So, I'm not sure I would see any benefit to having the Mild to Wild. By the way, I've had W2W in previous C6's and love it.

Good question. I took the video over a year ago. It may have had the exhaust mode set to Stealth (where I normally run it). Then, using the remote (or Homelink), I can open the valves full time no matter how the DIC exhaust setting or mode **** is set. That was the main purpose I installed it. If driving in the neighborhood late at night, I can press one button and put the exhaust mode to Stealth and not wake any neighbors. Yes, I care about my neighbors.
The valves will still close at times - even in track mode.

Ex: Set center console exhaust mode to Stealth - exhaust is very quiet 90% of the time. Press a button, exhaust is as loud as it gets 100% of the time. Press again - back to Stealth sound.

The benefit is being able to have quiet or loud exhaust at the press of a button.
Ex: Set center console exhaust mode to Stealth - exhaust is very quiet 90% of the time. Press a button, exhaust is as loud as it gets 100% of the time. Press again - back to Stealth sound.

If it does NOT open the valves any more than what I have already choosing TRACK through the settings screen, then it's not a benefit for me.

Yep, I get that completely...... I've owned 2 of them before ( C6 ).... but my interest in this was that other posters were claiming that EVEN when the exhaust was set to TRACK, that at low RPM or at idle, the valves were not open 100% and this would be like pulling the fuse, open 100% of the time, until you pushed the button.

I'm going to do it because a manual closes the valves under partial throttle in 4-5 gear(regardless of mode) between 34-39 MPH. And, it would be on demand to close if I was at a track that I have troubles with the DB meter. Real quick, no BS, just use the button in trouble areas and back open later.
