How many parts does an exhaust pipe consist of?

[DeAlina]

The exhaust pipe consists of three parts: the header, the mid-pipe, and the tailpipe. The header of the exhaust pipe is the exhaust manifold, the mid-pipe is the longer tube located under the chassis, and the tailpipe is the section near the rear bumper. The exhaust pipe is equipped with a muffler to reduce the noise of the exhaust. More details are as follows: 1. On the exhaust manifold, there is also a catalytic converter, which reduces the content of pollutants in the exhaust gas, thereby protecting the environment. The exhaust manifold can be seen by opening the engine hood, as this component is located in the engine compartment. 2. The exhaust manifold also has oxygen sensors, which are located both before and after the catalytic converter. The oxygen sensors detect the oxygen content in the exhaust and send signals to the ECU, allowing the ECU to adjust the air-fuel ratio based on this information.
