What are the effects of blocking a car's exhaust pipe?

[VanIsaac]

The effects of blocking a car's exhaust pipe are: 1. The car will experience difficulty in accelerating, with challenges in increasing engine RPM and speed; 2. Automatic transmission vehicles will be forced to frequently downshift; 3. Engine power will decrease, and exhaust emissions will exceed standards; 4. The engine may shake, the malfunction indicator light may turn on, and the engine may frequently stall; 5. The exhaust pipe will continuously heat up, potentially reaching the ignition point of nearby components, leading to spontaneous combustion. The exhaust pipe is installed between the engine's exhaust manifold and the muffler, providing flexible connection for the exhaust system and serving to reduce vibration and noise. Maintenance methods include: 1. Preventing water from entering the inside of the exhaust pipe; 2. Applying rust-proof oil inside the exhaust pipe; 3. Regularly inspecting the condition of the exhaust pipe.
