How long will it take for problems to occur if a steel wool ball is placed in the exhaust pipe?

[CarmenLynn]

If a steel wool ball is stuffed into the exhaust pipe, it generally won't cause any significant impact on the vehicle. Unlike rubber or similar materials, a steel wool ball cannot seal the exhaust pipe. Even if the steel wool ball gets stuck and cannot be removed, the engine can still expel exhaust gases. Below is an introduction to automotive exhaust pipes: 1. Definition and Composition: The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe generally consists of a front exhaust pipe and a rear exhaust pipe. 2. Precautions: Avoid prolonged high-load driving in low gears and prolonged high-revving while stationary, as both can cause damage to the engine and muffler.
