Can I drive a car with an exhaust leak?

Driving a vehicle with an exhaust leak poses significant risks and is not recommended. An exhaust leak can cause abnormal exhaust emissions, directly affecting engine performance, manifesting as reduced power, increased fuel consumption, and difficulty accelerating-this is particularly noticeable in turbocharged models. If the leak is located in the front or middle section of the exhaust system, it may cause an imbalance in exhaust back pressure; long-term neglect can corrode the metal components of the exhaust pipe and even lead to breakage. Additionally, the leak may allow harmful substances to enter the vehicle interior or cause carbon buildup, threatening the engine's lifespan. It is best to stop the vehicle immediately upon detecting a leak and contact professional maintenance to avoid further damage or safety hazards. Repair costs depend on the extent of the damage; typically, replacing local components costs several hundred to over a thousand ringgit, and if core components such as the catalytic converter are involved, the cost may be higher. Regular inspection of the exhaust system's sealing can prevent such problems.
