Car tail drum modification, car modification tail drum

Hehe, I'm a tuning technician, (self-taught) Hehe, first of all, please LZ don't underestimate the modified exhaust system. There are many types of exhaust system modifications for automobiles. It can be divided into the middle section of the head coke (plantain) and the tail end.

You said that you want to change the tail section is good, I will tell you some professional, generally modified car tail section is divided into many kinds, the most common two kinds. One is the straight row, and the other is called the back pressure tail drum. Generally speaking, if your car is biased towards torque, you should use back pressure, and if you have more horsepower, it is really good when you use inline high-speed.

But the premise of all this is that there must be a supporting head focus and interruption. Without these supporting things, all you pay is in vain, and all you get is noisy noise.

The general tail section of the profession can be divided into: High-grade type, M-type roundabout internal back pressure, 2. Mid-grade: double reflux internal back pressure and buckle edge inner S drum.

Oh, the above is popular, I still hope that LZ will not make it himself. If you can really make it, you still have to start from the head, or it will be useless at all. It is recommended that you go to a tuning shop to choose, it is not very much, and it is very effective!

Hehe, in China's tuning industry, but the materials are difficult to meet the standards, if LZ is in Beijing, I know a place where someone has been doing this for a long time.

By the way, there is a ternary in the exhaust system, and that thing is a must. It's also a big problem, and there is no way to inspect the car without that, and it's generally in the middle of the section, and a small number of cars are in the plantain Oh, pay attention!

Although the data is not professional, I feel very superficial, and I don't have the ability of LZ. Haha, I can only tell you some basic knowledge of modified exhaust, hehe, if you need to know the place where the exhaust is done, I'll come back

PS The first floor said that the control of fuel consumption and power is very correct, but not the exhaust pipe, but the entire exhaust system, if there is a tail section of the middle section and the head of the original factory, there is no change just a silencer.

There's so much data out there, and it's all about finding it as you go. The important thing is the size of the size as well as the size of the inside. Everything else is simple. If it is modified, it is just a change in the pipe.

Don't underestimate an exhaust pipe. I used to hear a professional tuner on the radio say that the exhaust pipe is not just silencing, it also controls your power and fuel consumption. I don't know exactly why, because I'm not a carmaker.

I've only heard of these kinds of shows. Just to remind you not to look at the exhaust pipe so simply.

I don't know, what car do you have? Look at the displacement and the effect you want to achieve!

Inline row for general turbine vehicles.

Back pressure is used for small displacements.

Let's use a straight row for the above.

Inline: The car is too noisy and loses its low torque.

S drum: There are two expansions, and the S-shaped elbow is clearly visible on the outside. Its clever design avoids the hassle of an exhaust drum that is too large to install.

The horsepower of the S drum should be increased by more than 7% after the modification, and the exhaust sound also looks racing-like. But some low-turn torque is lost.

G Drum: There is a triple expansion design, which increases the horsepower while minimizing the loss of torque with a larger expansion rate (the horsepower increase is inferior to the S drum, but the torque loss is less and almost zero), and the sound is more subdued.

H drum: Specially used for high-end sedans and sports cars, because they have a large exhaust volume and often only design one exhaust drum (no middle drum design), and its size should be designed according to the car displacement. (This introduction is more general, I don't know how to use the automatic transmission, and I don't introduce the advantages and disadvantages.)

I heard that the voice is charming.

M drum (variable back pressure tail drum.

First of all, let's understand what it is called"Variable back pressure"?Take the world-class brand REMUS, for example, in the back pressure drum has his original design (the specific patent details of the question to ask the manufacturer), simply put, in the back pressure drum to design a valve that can automatically adjust the opening and closing through the amount of air flow. When you are at low speed, the valve closes, giving enough back pressure to increase the torque.

So that the vehicle is more powerful at low speeds; As the speed increases, the air flow gradually increases, and the valve gradually reaches the complete at high speed, so that the exhaust is completely unimpeded, and the vehicle will run more smoothly and powerfully.

Plantain: Also known as an exhaust branch or exhaust manifold. In general, 4-cylinder civilian vehicles with small and medium displacement have 4 exhaust paths converged into 1 road, and poorly designed exhaust branch pipes form turbulence when the engine rotates high.

It will cause poor exhaust. When modifying, you can choose a 4-out 2-in-1 exhaust manifold. Most of the exhaust branches of the original car are cast by pig iron, and when conditions permit, when the exhaust branch is modified, it can be customized to make high-temperature resistant titanium alloy modification supplies!

Enough detail!

1.In terms of sound, the straight row is the loudest, the S drum is the second, the G drum is the second, and the M drum is the least loud.

2.The differences and principles are described above.

3.If you're looking for sound, let's choose a straight row haha.

5.It is not legal to change the tail drum.

It's definitely not legal, noise is pollution, and emissions can't be passed. Switching to an inline row loses power at low rpm.

When it comes to modifying the exhaust drum, it can probably be divided into the following types, but the effect is definitely different! One. Disadvantages of inline row: noisy, suitable for large-displacement street cars.

Two. S drum disadvantages: unstable back pressure, intermittent sound at high frequencies, and sharp sound!

Three. Advantages of internal back pressure drum: This kind of drum inherits the advantages of S drum, and at the same time changes the intermittent sound in the high-frequency design, and the stability of the back pressure becomes disadvantageous: the sound is not deep enough, and the noise is still not small.

Four. Advantages of double reflux internal back pressure: After the design of double reflux, the back pressure effect is more stable, and the power increase is more prominent Disadvantages: round drum design, the noise is slightly larger than that of M drum.

Five. M roundabout variable back pressure advantages: flat drum, good mute effect, multiple roundabout reflux design, can have a better back pressure effect at different speeds, with different straight pipes and elbows in the package to change the exhaust pressure, so as to better improve the power Disadvantages: **High.

The above are relatively common, of course, there are Y drums, G drums, etc., and their performance remains to be verified!
