What happens if I turn my car off at high speed and turn it back on? Can I break something?

I had a loose wire in my ignition circuit. The engine lost all power, and then reconnected again after about five seconds.
It blew the entire exhaust system to pieces. The silencer (muffler) split all the way down the weld and became a flat sheet. The whole exhaust would have filled up with unburnt petrol/air mixture, and then it all got ignited by the next successful fired cylinder.
I don’t see why you would damage a manual transmission (having the wheels drive the engine is no worse that starting the engine by pushing or towing the car).
Unless you disengage the clutch (on a manual transmission), I don’t see why you would lose power steering or brakes. The wheels are still turning the engine, and typically the steering pump is driven by a belt off the engine, and the brake vacuum reservoir is sustained by the pipe from the inlet manifold.
Automatic transmissions may behave differently, although the transmission fluid pump would still be driven off the drive shaft at the engine end.
