Still have the stock F430 muffler with the valves (for now) and I have to say once the exhaust is run to meet into a large center tip in the middle of the bumper I think it will be even louder. With the valves it will allow the car to be civil enough to drive slowly through neighborhoods without everyone calling the cops BUT when it’s revved with the valves open it is LOUD and sounds so so good :)
