I don't believe you have the choice to have it open all the time. That would allow the customer to defeat a Federally mandated requirement for noise pass by, which I don't think the OEM can do. It would be like enabling the customer to turn off airbags.

I believe it is conveniently priced at or just below many of the top notch aftermarket exhausts. And those are loud allllll the time. Even on the highway, which I don't prefer. I do not like an open exhaust on long trips, Sam I am. But many do and many will prefer an aftermarket solution.

It is now available on the SS for 2016. When I bought mine last year (2014 model), it wasn't available. It isn't an option that is so awesome it makes me want to trade in and get a 2016.

I believe the car will start up in Tour by default which only opens the valves under power (not sure what throttle setting). Sport and Track (for the SS) will definitely leave it open most of the time. I believe I even heard its open on startup then closes in Tour. So you can actually leave it fully open all time time, but I bet it will revert to closed until the setting is changed again. From info we have heard in press releases and from Al, I'm thinking they have changed the settings from the C7's NPP, but check out this video.

You can actually hear the exhaust change as he toggles the setting.



Also the Scat Pack cars have their valves open in in sport mode, which can be made the default mode for the car. So sound regulations must be peculiar.
