For a car, it is necessary for car owners to understand some common sense issues, so that they can roughly determine the cause when they encounter a fault. For example, I don’t know if car owners have noticed that some cars have only one exhaust pipe, while others have two. So, what is the difference between one exhaust pipe and two exhaust pipes?

Regarding this issue, first of all, we need to know what effect the exhaust pipe has on the car. On the surface, it is actually very simple. It is connected to the engine, which can discharge the exhaust gas generated by the engine, and can also reduce the pressure of the exhaust gas. In addition, the exhaust pipe is generally curved and long, which actually reduces the noise generated when exhausted. It can be seen that the role of the exhaust pipe is still very important, but what is the difference between one exhaust pipe and two exhaust pipes? In fact, we can use the exhaust pipe as a nose. One exhaust pipe is equivalent to the other nostril being blocked, and we can breathe but not very smoothly. The same is true for the exhaust. The two exhaust pipes can discharge the exhaust gas from the engine in a more timely manner to ensure that it will not stay in the engine, thereby improving the performance of the engine.

Not only that, but the number of exhaust pipes is also related to the current people's psychology, which is also very concerning to many manufacturers. Relatively speaking, the number of exhaust pipes can reflect the performance of the car to a certain extent. Like some large-displacement models, the exhaust pipes basically use two sides and four outlets. In ordinary family cars, many of them have a single output on one side or a double output on one side. Therefore, the manufacturer has also seen through everyone's psychology. Even some small-displacement models will deliberately add a few exhaust pipes to the rear of the car, which looks really bluffing. In fact, the number of exhaust pipes does not need to be too many, too many will make the exhaust too smooth and increase fuel consumption for no reason.

Finally, it is necessary to mention that if there is a problem with the exhaust pipe, it is basically necessary to replace it together. For example, if one of the exhaust pipes with two sides and four outlets is broken, the other four must be replaced; From this point of view, if it is a family car, that one exhaust pipe is completely sufficient. Even if it is broken and needs to be replaced, the maintenance cost will not be so high. Moreover, although many models now have two or four exhaust pipes on the surface, in many cases only one exhaust pipe is working. Only when the vehicle speed is fast, such as driving at high speed, will multiple exhaust pipes work together.
