From factory our car is set to run dual exhaust system for maximum engine performance. If you take a look at the OEM design it is a single pipe unless you go into Sport then the valve opens. Thus reducing back pressure leading to better performance.
Dinan even at open seems to be running single pipe by the way it was looking from the air flowing in the video. This will create more back pressure hampering performance.
