I've noticed that the Porsche tuning shop sharkwerks offers a GT3 exhaust that has a valve system, which allows the car to sound relatively normal while not in sport, but when in sport mode the valve opens. This allows more power and some serious sound. Are there any similar systems available for M3s?
