Hello, a while back my NPP exhaust valves stopped working. The valves are stuck in the “Track mode” position. Usually when I switch modes I can hear the valves moving and the exhaust tone changes slightly. But when I switch exhaust modes I cannot hear the valves moving or the exhaust tone changing. I am wondering how I can fix this and what needs to be replaced. My car also has the borla atak system if that makes any difference. Thank you for any answers.
