You can continue driving with a broken exhaust manifold. What is an automobile exhaust pipe: Also known as the automobile exhaust flexible hose, it is installed between the engine exhaust manifold and the muffler, creating a flexible connection for the entire exhaust system. This helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust muffler system. It is primarily used in light-duty vehicles, compact cars, and buses. Its structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings at both ends. To enhance noise reduction, the corrugated pipe may include an expansion joint or mesh sleeve inside. Material: The main material is stainless steel SUS304, while the clamps and connectors can be made of stainless steel or aluminized steel. Exhaust pipe damage can be categorized into three scenarios: Front section damage, mid-section damage, and rear section damage (i.e., damage to the catalytic converter-free part). If the muffler section of the exhaust pipe is damaged, the primary effect is increased noise, with no significant impact on other vehicle performance. If the rear section of the exhaust pipe is damaged, not only does the noise increase, but the emissions also fail to meet standards, necessitating replacement. If there is only a small hole in the exhaust pipe, it will not cause a severe increase in fuel consumption. Theoretically, removing the entire exhaust pipe eliminates all exhaust resistance, leading to increased engine power and higher fuel consumption. Racing cars (including motorcycles) do not have mufflers in their exhaust systems to minimize exhaust resistance, though this results in extremely loud noise.
