I am new to C7's and Corvettes in general. I am kinda confused on the NPP exhaust so please bear with me. In order for the ride modes to activate the valves and open up in sport mode you have to have the exhaust option right? I did not get the exhaust option. Does anyone know if there is an aftermarket exhaust that will plug up to the ride mode option so that when you select "sport" for example it will open the valves as opposed to a mild2wild type remote control?
