Noise when Quad exhaust valve closes (left side exhaust only)
Hello fellow Camaro owners. I have an issue. Whenever the quad exhaust on my 2014 Camaro closes (whether i am reving the engine or after the car starts) the valves open to allow the 4 exhaust ports to vent, but when the engine slows down, the valves close and there is a wierd sound (hiss) that comes out of the driver side exhaust. I looked at it and the valves open and close normally, but the sound comes from the left side only when the valves close. I took it to the dealer and they said it was normal. I dont know whether to believe them or not. Please, if anyone has experience with this, let me know. Thanks.
