If you start it as soon as you push the clutch to the floor, it will be raucously loud, then get quiet as the exhaust valves close. If you wait a few seconds for the exhaust valve self-test to complete, it will start up in "normal" mode, and be quieter.
Every time the car starts, with the exception of the cold-start trick mentioned above, it resets to normal mode. You have to set the exhaust to sport mode, or set the whole car to sport mode, anew each time.
