Are you catless? I think I understand what you mean by it being quieter than stock on the 2019. My 2019 with a 200 cell cat is loud, but a bit unrefined and droney with the valves open….almost sounds like an old diesel truck when slowly cruising.

Also - are your valves open in comfort too? Maybe its just the mic, but I can hardly tell a difference in volume between sport and comfort outside of the burbles.
