Apparently, Chevrolet gets it.
Works like the vette. Not sure of actual throttle % and rpm, though. Most of us pulled the fuse to it so it stays open all the time, though. Or you can buy a Mild to Wild switch w/remote so you can control it yourself, or program it to a home link switch.
BTW, NPP exhaust is an option on SS and some, if not all V6 models.
