The Corsa while sounds amazing, definitely has a problem with their valve design. I am on my 3rd set of mufflers and have another valve rattling.

Corsa sent me a service kit that places a spring loaded washer on the button head end of the valve shaft. The problem is my valves are still the gen 1 that is all 1 piece. The last set of mufflers I received were supposed to be gen 2 which are serviceable.

So currently I am going back and forth with Corsa. Now they want to know if the car is modified...blah blah. Told them it's no different than a ZL1. Waiting to hear back.
