It is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler to make the whole exhaust system flexibly connected, thus playing the role of vibration and noise reduction, convenient installation and extending the life of the exhaust muffler system. It is mainly used for light vehicles, micro cars and buses. Its structure is double-layer bellows covered with steel wire mesh sleeve, and the straight side section at both ends is covered with snap ring. Material: The main material is stainless steel SUS304, the ferrule and receiver can be made of stainless steel or aluminised steel.
Normally, people may pay less attention to car exhaust Pipes, but if you have been paying attention, there are many cars on the road with different exhausts. Some have only one exhaust outlet at the rear of the car, some have one on each side, while others have two on each side.
The role of the exhaust pipe is simply to reduce exhaust pressure, reduce engine exhaust noise and reduce harmful gas pollution; of course, it is also related to the displacement of the car itself, which sometimes directly affects the power and fuel consumption when we drive.
The exhaust pipe does not simply discharge exhaust gases, but also purifies them, reduces noise, reduces vibration and controls the power range. The tail section of the exhaust includes the piping, the silencing kit and the tailpipe (exhaust hole), which is used to reduce noise and for decorative purposes.
If even one thick exhaust pipe is not enough for some cars, another one has to be added. Because the exhaust is more efficient this way, you will often see two exhaust pipes side by side on larger displacement cars. Some sports cars, in particular, need more air intake to get up to speed, so the exhaust pipes are designed to be particularly thick. To satisfy the suction and at the same time the emission of exhaust gases.
Generally, cars with a large displacement have more dual exhausts. When you think about it, you know that the exhaust pipe bridges the movement of the engine. So it is understandable that cars with a large displacement use two exhaust pipes. They need more air, so they remove more exhaust gases. One is completely inadequate for their needs. Some cars will use a configuration with one thick and one thin one, and as long as the sedan doesn't suffer from back pressure problems it will be fine.
So, regardless of whether there are 2 or 1 exhaust pipe, the internal construction is the deciding factor. Looking only at the surface exhaust holes is not an accurate way to judge how good a car's power performance is, and it is not the main factor in determining whether the car is premium or not.
