I drive most of the time with the throttle in sport mode, which opens the flaps when it wants to. With the flaps commanded fully open with my valve controller, it will BOOOOOOOOOOOOOOOOO all the time when cold. Pain in my ass.
I would love to find a muffler that sounds good and flows well with the valves totally closed, giving me the options of just driving it and enjoying like a car without any exhaust flaps or cracking them open when I want them loud.
I have an exhaust controller, but 'closed' = stock flap operation, so I still get the sudden change in tone/volume.

Cold start (warm cold starts included) + valves open = one of the worst sounds known to man
it’s cause the wastegates are fully open in cold start sequence
