What is the purpose of placing a magnet on a car's exhaust pipe?

The purpose of placing a magnet on a car's exhaust pipe is to capture magnetic particles generated in the return oil circuit, which helps protect the engine. Additionally, it can enhance the engine's power output—with fewer impurities, the engine naturally performs more robustly and can also help the vehicle owner save fuel. The magnet has strong adsorption capabilities, attracting any magnetic materials, thereby removing many iron particles and extending the engine's lifespan. The car's exhaust pipe is installed between the engine's exhaust manifold and the muffler, allowing the entire exhaust system to have flexible connections. This setup aids in reducing vibration and noise, facilitates installation, and prolongs the life of the exhaust muffler system.
