Exhaust system
The exhaust system is a contradictory meeting point on the car. On the one hand, it is very low-key, and most of it is hidden under the car body without being noticed. On the other hand, sports cars, performance cars and other models rely on the strong exhaust sound. And attractive. On the one hand, it is responsible for the environmental protection of emissions; on the other hand, it has a great effect on the power and weight of the vehicle. In terms of the layout of the exhaust pipes, there are also great differences. Some are hidden from view, and some are designed to be exaggerated and cool. What is the reason for this difference in style? What are the little-known secrets of the exhaust pipe? Let's take a look together today.

The basic composition of the exhaust system
Because the exhaust gas is not discharged directly, but can be discharged after being filtered by various parts of the exhaust system. Automobile exhaust system refers to the system that collects and discharges exhaust gas, which is generally composed of exhaust manifold, exhaust pipe, three-way catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tail pipe. Among them, three-way catalytic converters and automotive mufflers are the core components because they are the most important for emissions, environmental protection, and noise control.
