Friends who are familiar with car exhaust pipe ports will find that some have only one exhaust port, some have one on both sides, and some have two on each side.

Usually, when people say that a car has a large displacement, it means that the car inhales more air and emits more exhaust gas; and the smaller the intake air, the less exhaust gas needs to be discharged.

However, the exhaust pipe is particularly thin, which will affect the smoothness of the exhaust, which will directly affect the power of the car.

In some cars, a thick exhaust pipe can't meet the demand. You can add a pipe for exhaust gas, and two exhaust pipes can meet the demand. As for some pipes at the end of the rear of the car, and some pipes at the end of the rear of the car, the position of the exhaust pipe will be different according to the design of the car.

The layout of the bottom parts of each model is inconsistent, and the remaining space is also in a different position, but the car can only design the position of the exhaust pipe according to the space. Exhaust volume has its own requirements. The exhaust noise of the two exhaust pipes can also be slightly lower, because the exhaust pipes are equipped with a muffler. Exhaust pipe mould After the exhaust gas passes through, it is divided into two, and they will all pass through the muffler. Exhausted, the muffling effect can of course be enhanced a bit.

Large displacement and high performance are generally a symbol of two exhaust pipes, and they look particularly domineering, so many car owners modify their own vehicles with exhaust pipes, directly changing one to four, in order to look better. .

Small-displacement cars do not emit a lot of exhaust gas. Although there are two exhaust pipes, when the car is idling, only one exhaust pipe is exhausted, and the other pipe is chicken ribs or auxiliary. On high-speed roads, when the exhaust gas becomes very large, the other exhaust pipe works.
