The service life of a car's exhaust pipe is typically 3 to 5 years or approximately 60,000 to 100,000 kilometres, with the exact duration influenced by various factors. Regarding materials, stainless steel exhaust pipes are more durable than ordinary iron ones due to their superior corrosion resistance; the latter tends to rust in high-temperature and humid conditions. Driving habits also play a critical role: frequent rapid acceleration or high-load operation increases exhaust pipe wear, whereas smooth driving minimizes stress. For routine maintenance, regularly inspect the exhaust pipe for rust, cracks, or leaks, ensure the muffler's drain hole remains clear to prevent water accumulation and corrosion, and avoid prolonged idling. If significant rust, abnormal noises, or leaks are observed, the exhaust pipe should be replaced promptly. Proper maintenance and good driving habits can extend the exhaust pipe's service life, ensuring smooth vehicle emissions and driving safety.
