Why does modifying the exhaust have the effect of increasing horsepower

1. The modified combustion and combustion tease exhaust can improve the power, but only the modified head section can improve the power, and the middle and rear sections of the modification cannot improve the power. It is possible to modify the sound of the middle and rear sections. The exhaust pipe of a car has three sections, which are front, middle and rear.

2. The front section can also be called the head section, the head section is actually the exhaust manifold, and the three-way catalytic converter is installed behind the exhaust manifold.

3. The head section of the exhaust pipe of the car only has an exhaust manifold and a three-way catalytic converter.

4. The exhaust manifold and the three-way catalytic converter have a great impact on the power, and the three-way catalytic converter has resistance.

5. However, after the modification of the high-flow ternary, the horsepower output of the engine in the high-speed area is improved, and the smoother exhaust will lead to the deterioration of the engine's low torque. Therefore, family cars are not suitable for high-flow ternary. Only racing cars that focus on horsepower output in the high-revving area are more suitable for high-flow ternary.

6. Some racing cars will not install a three-way catalytic converter in order to pursue a smoother exhaust.

7. The middle section is the long tube on the chassis of the car.

8. The rear section can also be called the tail section, and the rear section is the part close to the rear bumper.

9. It is recommended that you do not modify the exhaust of your own car casually, as casually modifying the exhaust will not only affect the power and fuel consumption, but also illegal acts.

Modified exhaust can increase power, but only the modified head section can increase the power, and neither the modified middle nor the rear section can increase the power. Modify the middle and back sections to change the sound. The exhaust pipe of a car has three sections: the front, middle, and rear.

The front section can also be called the head section, which is actually the exhaust manifold, and the three-way catalytic converter is installed behind the exhaust manifold.

The head section of the exhaust pipe of the car only has an exhaust manifold and a three-way catalytic converter.

The exhaust manifold and the three-way catalytic converter have a strong influence on the power. Three-way catalytic converters have electrical resistance. If you change to a three-way catalytic converter with a large flow rate, the power can be increased.

However, the high-flow ternary system modification has improved the horsepower output of the engine in the high-rev range, and the smoother exhaust will lead to the deterioration of the engine's low torque. Therefore, family cars are not suitable for high-flow ternary. Only racing cars that pay attention to horsepower output in the high-speed area are more suitable for high-traffic three-way royal trouble.

Some cars don't have a three-way catalytic converter in order to get a smoother exhaust.

The middle section is a long tube on the bottom ballast cover plate of the car.

The rear section can also be called the tail section, which is the part close to the rear bumper.

It is recommended that you do not modify the car exhaust casually, which not only affects the power and fuel consumption, but also illegally.

The modification of the exhaust can increase the power, but only the modification of the head can increase the power, and the modification of the middle and rear sections does not increase the power. Modify the middle and back sections to change the sound of the slag. The exhaust pipe of a car has three sections: front, middle, and rear.

The front section can also be called the head section, which is actually the exhaust manifold, and the three-way catalytic converter is installed behind the exhaust manifold.

The head section of the exhaust pipe of the car only has an exhaust manifold and a three-way catalytic converter.

The exhaust manifold and the three-way catalytic converter have a strong influence on the power. Three-way catalytic converters have electrical resistance. If you change to a high-flow three-way catalytic converter, the power can be increased.

However, after the modification of the high-flow ternary system, the horsepower output of the engine in the high-speed area is increased, and the smoother exhaust will lead to the deterioration of the low torque of the engine. Due to the height of the ball, the family car is not suitable for the use of large-flow ternary. Only in the high-speed area where horsepower output is focused on racing cars are more suitable for high-flow ternary.

Some race cars will not be equipped with a three-way catalytic converter in pursuit of a smoother exhaust.

The middle section is a long tube on the chassis of a car.

The rear section can also be referred to as the tail section and is the part that is close to the rear bumper.

It is recommended not to modify the exhaust of the car casually, which will not only affect the power and fuel consumption, but also be illegal.

Millions of car purchase subsidies.

There are three types of exhaust: the first section (also called the full section), the middle section and the tail section. The effect will be different depending on the part of the modification.

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 smoother, and it is easier to use 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.

Tail: Generally a silencer. It doesn't make much difference whether you change it or not, just make it loud.

Attached to China's car modification regulations:

According to Article 16 of the Regulations on the Registration of Motor Vehicles of the Ministry of Public Security:

In any of the following circumstances, the owner of the motor vehicle does not need to apply for a change of registration without affecting the safety and identification number plate:

1) small and micro passenger vehicles installed front and rear anti-collision devices;

2) Freight motor vehicles are equipped with windshields, water tanks, tool boxes, spare tire racks, etc.;

3) Increase the interior decoration of motor vehicles.
