What Happens If You Stuff a Steel Wool Ball into the Exhaust Pipe?

[Maria]

The consequences of stuffing a steel wool ball into the exhaust pipe: The engine will no longer function, causing the car to stall directly. If the steel wool ball is inserted while the car is parked, it may prevent the engine from starting. The car's exhaust pipe is designed to expel the waste gases produced after engine combustion. Blocking the exhaust pipe will affect the smooth flow of exhaust gases, thereby disrupting the engine's normal operation. If the engine is started, stepping hard on the accelerator can forcefully eject the steel wool ball. The exhaust pipe has backpressure; if it is too open, the car may lack power at low RPMs but will improve performance in the high RPM range. Conversely, if the exhaust pipe is not very open, it will enhance the engine's power performance at low RPMs but limit its performance in the high RPM range.
