After changing the exhaust to improve the air, does the bellows have an effect?

What is lost is the torque at low speeds, acceleration will be weak, and fuel consumption will increase. And then there's the noisy. What you get is acceleration at high speeds, at high speeds. If the landlord's car has a displacement, it is useless except for loading 13. Harmful and unprofitable.

There is no need to change the exhaust after the car is improved, and some people may change the exhaust in order to pursue a fashionable appearance, but basically there is no need to change it.

The air intake system of contemporary automobiles is mainly a variable air intake system. There are four main types of variable intake systems: VVT (Local Variable Valve Timing), CVVT (Continuously Variable Valve Timing), VVT-I (Electronic Variable Timing), and I-VTEC (Electronic Variable Valve Lift). The combination of parts and components that introduce air or mixture into the cylinder of the Kirimoga engine is called the engine intake system.

The functions that improve the exhaust can be broken down into three categories. The first is to satisfy the visual effect, that is, the aesthetic of appearance; the second is to meet the visual and auditory effects; The third is to reduce the exhaust back pressure, which is conducive to the performance of the vehicle at high speed. The exhaust pipe is located between the engine exhaust manifold and the muffler, and its role is to reduce vibration and noise, facilitate installation, and extend the life of the exhaust muffler system.

The exhaust is divided into a head, middle, and tail section. The effect will be different if you modify different parts.

Modified head section: Because the head section is the part where the engine is directly connected to the exhaust system, it is the most effective and the most expensive. The effect is to make the exhaust flow smoother, making it easier to exert the horsepower of the car at high speeds.

Mid-section modification: mainly to replace the three-way catalytic converter to control the exhaust back pressure. Retrofitting reduces exhaust resistance, which improves the vehicle's dynamic performance at high speeds.

However, the more back pressure is discharged, the lower the torque will be, so the acceleration performance will also decrease. If it is a car with a large displacement engine, the effect of replacing the middle section is still obvious.

Modified tail section: generally a silencer, which can change the size of the exhaust sound wave.

Choose according to the vehicle type.

There will be a lot of styles of exhaust pipes, not any one we can use, before modifying the exhaust pipe, you need to pay attention to the style of the exhaust pipe of the original car, pay attention to whether it is straight or curved, many car owners will choose a straight type in order to have a smoother exhaust volume, and the random replacement of the exhaust system may not be suitable.

Car displacement to choose the sound.

Many car owners in order to achieve a better exhaust effect, in the modification of the exhaust pipe also put a lot of effort, only modify the tail of the exhaust pipe owners are not a minority, this approach is actually wrong, because for the exhaust system, responsible for the sound of the part, not only in the tail, concentrated in the tail and middle section of the exhaust pipe, do not modify only a part of the exhaust pipe, to consider more.

Isn't the displacement of the exhaust pipe thicker and shorter the better?

Many car owners understand the operating principle of the exhaust system, so in terms of modification, they will mistakenly think that the thicker and shorter the exhaust end, the better, in fact, the displacement of the exhaust system is directly related to these, and more related to the displacement of the engine of the body itself, so we must not only pay attention to the displacement situation and ignore the principle of the exhaust system, which will get the opposite effect.

Car modification exhaust pipe brings great convenience to our travel, but we also have to pay attention to the details of whether the exhaust pipe is modified, we must not blindly modify, we must ensure the premise of safety and practicality, and then confirm whether it really needs to be modified.

end precautions.

1. Modification is to choose a type suitable for vehicle use, which can effectively improve the performance of the car.

2. The quality of the exhaust pipe material of the car also has a great impact on the performance of the car.

1. It must be matched with the engine, otherwise it will affect the power of the engine.

2. Pay attention to the noise after modification, 3. Pay attention to the position of the exhaust pipe and the rationality of the layout during the modification.

1.The original air separation.

The pros and cons of car air intake modification, how to modify air intake.

Many modified brands will launch a special original air separation for the model, because the replacement cost of the shirt is low, so it has a good cost performance, plus it is the original replacement, there is no other changes, so it will not change the output characteristics of the engine, and can effectively improve the air intake efficiency while ensuring low torque. Of course, the effect is limited.

Because the original air filter element for cost considerations, most of them are dry paper materials, this dry paper material uses a paper filter to filter dust and foreign matter, and the air will enter the engine through the small holes in the filter, and after a long judgment and time, the surface will absorb a large amount of dust, forming resistance to the air intake, and the air intake efficiency will be reduced. Therefore, it needs to be replaced frequently.

The modified high-performance air filter element is made of cotton or sponge material, plus a special filter oil to block dust, due to the use of three-dimensional filter media (criss-cross cotton filter element), dust will be blocked in the layers of wrapped cotton filter element, larger dust will be filtered by the oil filter stick to the surface of the filter screen, but also play a role in filtration. Cotton filters don't lose their air intake performance once the holes are clogged with dirt like paper filters, so they are more efficient and last longer. Sponge filters have a higher suction capacity than cotton filters.

The high-performance air separation launched for various models on the market is usually about a few hundred yuan, which is definitely a very cost-effective modification project.

2.Carbon fiber bellows.

The pros and cons of car air intake modification, how to modify air intake.

The above also mentioned the influence of temperature on air volume, and one of the characteristics of carbon fiber material is that it has the characteristics of slow heat transfer, so the modified carbon fiber bellows can better isolate most of the heat in the engine compartment, so that the intake temperature is reduced, so as to improve the purpose of air intake performance. Of course, as long as it is related to carbon fiber, ** will also go up.
