I do actually use 50% open setting most of the time however it really does not cause much reduction in volume. I’m not a fluid dynamics engineer but I believe it’s simply that a 50% opening is still much less restrictive than the alternative which is going through the muffler system, and the majority of the exhaust flow follows the path of least resistance. What the 50% setting does do is take out a little of the drone that occurs with the valves open at partial throttle and low/mid rpm. So to summarize it’s a nice setting but don’t expect anywhere near a 50% volume reduction.
