Exhaust Valve Issue After Catback System Installed
I currently installed a fi exhaust catback system on my 2019 coupe, the next morning i went to start it and noticed the rear exhaust valves do not follow the cold start sequence the valves go from the open position to closed and stay closed
•The valves do work when the exhaust button is pressed from the cabin
•valves open when the car rpm increases
•i have a simulator connected for the middle valve
•i have had the car scanned and no faults found
The valves just wont open how they normally would during cold start
Has anyone came across this same issue or know what the issue may be?
