exhaust systems

[jick.cejoco]

With the heat and pressure of the exhaust gases, any condensation (likely minute anyway) will just dry off and be expelled later on.

the maximum allowable exhaust backpressure on most cars is 1.25 psig right before the catalytic converter. behind the catcon is usually at atmospheric pressure or 1 BAR. the pressure is not sufficient to expel the accumulated water condensation
