Next time you takeoff, try this...
Years ago I did the calculations, and the blade tip speeds are near supersonic.
Bring the RPM back a hair after takeoff and you will hear that 'gnrrrrr;' dropoff instantly. Also, the rear prop 'chops' the rear exhaust. On my T337 that's a large exhaust pipe. But never an issue.
