How long will a car exhaust last?

The service life of an automobile exhaust pipe is typically 3 to 5 years or 60,000 to 100,000 kilometres driven, but the specific duration is affected by various factors. Humid and salt-rich environments accelerate corrosion and shorten the exhaust pipe's lifespan, while stainless steel is more corrosion-resistant than iron and suitable for long-term use. Aggressive driving and high-load operation intensify exhaust pipe wear due to high-temperature and high-pressure exhaust gases, whereas smooth driving helps extend its service life. Regularly inspecting the exhaust pipe for rust, cracks, and leaks, keeping the muffler's drainage holes unobstructed, and avoiding water accumulation are key measures to prolong its lifespan. If significant rust, leaks, or abnormal noises during driving are detected in the exhaust pipe, it should be replaced promptly to ensure driving safety and proper exhaust emission.
