Likewise, a tuned exhaust system allows the engine to operate more efficiently. There is no propeller control. Instead, as with the SR20, the throttle also controls prop rpm. At full throttle, the prop turns at 2,700 rpm. When you initially reduce power, the prop goes to 2,500 rpm, but manifold pressure stays the same.
Further reductions decrease manifold pressure until reaching a detent.
Below the detent, both rpm and manifold pressure are decreased. As a practical matter, you fly it just as you would any other airplane, except with less fussing around. Set full throttle for takeoff, reduce to 2,500 rpm for initial climb, and leave it there until you level off. If the engine fails, you can pull the throttle back and the prop changes to a coarser pitch to reduce drag. There are no cowl flaps to mess with.
