Customer Question

I have a 2016 challenger scatpack. Im getting a CEL with the codes u113f and u1140, which are lost signal to active exhaust bank 1 and 2. When at wot it sounds like the exhaust valves are stuck closed and the exhaust make a whistle noise. This didnt make sense to me because i thought the exhaust fail open. Is there any way to reset the active exhaust?
