[0002] The exhaust pipe is an important part of the car. It is not only responsible for exhaust gas, but also bears the function of noise reduction and extending the life of the exhaust muffler system. It is mainly made of stainless steel, which can effectively reduce the huge noise generated by the exhaust gas emission of the car. Its working principle involves the design of the back pressure pipe. The back pressure is generated by the grid muffler or volume change in the pipe to help the mixture to achieve complete combustion, thereby reducing noise and improving low-speed torque. In addition, water ingress into the exhaust pipe usually does not cause obvious symptoms, and the accumulated water will be discharged during the operation of the engine. The exhaust pipe of the car plays a key role in reducing noise. Its design and material selection have an important impact on the performance and driving experience of the car.
