From what I recall this one does have some wave cancellation so it is better than most aftermarket exhausts in terms of drone. Better than stock? I don't think so. It loses hp and torque below 4800rpm which is a critical area IMO. I would love to lose 15 lbs off the tail of my car but I am not willing to sacrifice mid rpm torque to do so. Porsche spent way too much money and engineering to get the performance and sound just right within their sound constraints.
