certified powered aircraft nearly never have a door through which in flight exit is intended by design, let alone possible
There's the Robin DR series, of which I have flown the 400 frequently, that have a forward-sliding canopy that could possibly be opened in flight - but how easy it would be to exit the aircraft
in extremis I don't know (and don't want to).
I do know that it would be very difficult to wear a 'chute and fit well enough in the seat to actually fly the aeroplane!
