How to Determine if the Exhaust Pipe is Clogged?

[JaceRose]

If the exhaust cannot escape and fresh air cannot enter, the spark plugs will fail to ignite, preventing the vehicle from starting. The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. Below are methods to determine if the exhaust pipe is clogged: 1. The sound is slightly muffled when accelerating sharply. 2. In severe cases, the exhaust pipe may turn red after a few minutes of acceleration. 3. You can also remove the exhaust pipe and inspect it using an automotive endoscope. 4. Use the cylinder cut-off method to determine by sequentially cutting off fuel to each cylinder to identify abnormal cylinders and damaged components.
