The Dinan has almost no drone, especially if you leave the resonator in place. I personally run a fabspeed sport cat, Dinan res delete, and Dinan axle back. It drones with the valve open, but I run the macht schnell valve delete specifically so I can run with the valve closed (about 70% of my driving) in any drive mode. With the valve closed there is almost no drone. Without a sport cat, there is no meaningful drone in either valve position.
