Anybody, i need help! I have a 2016 challenger scat pack and i just installed a flowmaster cat back system outlaw. CEL turned on. I brought it to different shops and they didnt know what to do. I called flowmaster, they made me watch a video and told me that theres just a problem with the exhaust valve actuator installation(springs and washers). We tried reinstalling them but no luck. Have any of you guys experienced the same thing?
