How to make a muffler quieter
As a rule, the owner of a motorcycle will do everything to be heard. There are a lot of tips on how to make the roar of an engine unforgettably loud. But what to do if, on the contrary, you want to get rid of the “wild roar”? Here are some tips:
- Install another muffler specified by the manufacturer.
- Replace the muffler filling with soundproofing material.
- Instead of the factory one, install a two-chamber full-size muffler.
- If the loud sound is due to wear on the inner tube, it should be replaced.
- Install a resonator. In the resonator chamber, the sound is damped before it enters the muffler can.
- Use additional resonating tips.
- Acoustic film may help. It is used both outside and inside the muffler, as well as around pipes. It reduces vibrations and decibel levels.
- Install the catalytic converter. In general, it is designed to reduce the proportion of harmful substances in exhaust gases, but it also does a good job of sound insulation and vibration.
Exhaust functions on a motorcycle. Problems and solutions.
In modern motorcycle society, there is a stereotype that the exhaust is an opportunity to customize the sound. This is partly true, but let’s not forget that the most important function of the exhaust system is to remove engine exhaust gases, as well as cool the exhaust gases, use the pressure pulsations generated at each power stroke, reduce noise levels and be environmentally friendly.
The main problem that motorcycle owners face is the backflow of exhaust gases. During operation of a motor vehicle, the engine faces high loads and extreme temperatures. During the release of gases, high and low pressure waves are formed in the exhaust system, which allow the exhaust gases to escape and prevent the fresh mixture from flowing out through the exhaust channel. As a rule, two-stroke engines are more sensitive to backflow.
In order for the motorcycle engine to operate smoothly, it is necessary to correctly calculate the length of each exhaust system pipe, starting from the exhaust manifold.
Types of mufflers
A motorcycle muffler is a device that weakens the sound of the engine. Mufflers are needed not so much to reduce noise as to change the timbre. And high-frequency sounds have a more unpleasant effect on the human psyche and ear than low tones.
Many people associate the roar of sports motorcycles with a muffler. And they believe that filling the muffler can reduce the power of the car. But that's not true. When replacing or modifying a muffler, only a small amount of horsepower is lost.
There is an intake and exhaust silencer. And scientific research has proven that if you choose the right basic elements, you can improve the filling of the cylinder. Such mufflers are called resonant mufflers.
Noise suppression is carried out by the part of the muffler located behind the first partition, and it consists of an acoustic filter. These filters on sports motorcycles are made simpler, since a higher noise level is allowed in sports motorcycles.
When deciding to remake a muffler, you need to remember the following. Sometimes, when improving one part, you have to sacrifice the quality of another. No one has yet succeeded in creating a universal motorcycle.
Manufacturers recommend using factory mufflers for your motorcycle. The muffler cavity becomes covered with carbon deposits, which can close the acoustic filter channels. Therefore, the cavity of the device must be cleaned regularly. The resulting carbon deposits prevent the exhaust gases from escaping, and engine power is reduced. After every five to ten thousand kilometers, mufflers need to be cleaned.
The original mufflers are quite quiet and good. Their disadvantage can be considered their heavy weight and size. Many consider their high price to be a disadvantage. Silencers are produced by many companies, and you can use a non-original muffler if you wish. Most often these are open mufflers. In them, exhaust gases exit the engine without any obstacles. But they make a lot of noise.
Those who love the loud roar of motorcycles can buy the cheapest muffler, which does not muffle anything. But if the roar of the motorcycle does not suit you, then you will have to buy an expensive option.
These mufflers differ in design and material of manufacture. There are four types:
- Titanium. He is considered the best. It's light, looks nice, and doesn't get too hot.
- Aluminum. Light enough. It looks worse than titanium, but there is a drawback. You can get seriously burned.
- Carbon. Looks nice, light and cool. But its significant drawback is that even with vibrations it can crumble.
- Stainless steel. Strong and heavy, but very hot.
Each type of muffler has its own advantages and disadvantages. Therefore, you need to choose for yourself.
Motorcycle exhaust system tuning
Customers who contact us about tuning their iron horse want to increase engine power. We can do this in several ways:
- Installation of elements that weigh less than stock. Most often, such elements are made of carbon fiber. They can withstand the highest loads for a long time and are of reference quality. Their main disadvantage is their high price.
- Removing the catalyst. This is fraught with the appearance of a strong exhaust odor, however, it increases engine power and significantly reduces backflow.
- Comprehensive exhaust system replacement. Lightening, adjusting the sound, increasing the diameter of the pipe - all this will help your motorcycle be the first in any race!
- Optimization of muffler characteristics. Our clients often come to us with the problem of setting up sound. Experienced craftsmen can easily cope with this task by replacing the muffler.
Since we are official distributors of the famous brands Akrapovic, MagnaFlow, Gibson, Brospeed, Dynomax, Ractive, Mozart, we will be happy to give you a guarantee from the manufacturer and for our work. We are waiting for you for a free consultation at the address: Moscow, Sokolnichesky Val 1, cor. 1 or you can ask any questions you are interested in by calling +7(495)-142-43-27

DIY straight-through muffler
You can buy a direct-flow muffler in any specialized stores. They are usually of interest to young motorcyclists who dream of high speeds. But real bikers are not sold on stickers from famous brands. They do everything they need with their own hands.
If you want to enter the world for real men, you need to make a direct-flow muffler with your own hands. When riding at normal speed, its noise will not be different from other motorcycles. But as the speed increases, the characteristic rumble of the engine appears. What do I need to do?
- Take a piece of pipe that has a diameter of 60 mm and cut it in half. First, one part is processed and a flange is welded in the middle. The outer part does not change. This is the inlet pipe. In half of the pipe, which is located in the muffler, you need to drill a large number of holes using an electric drill. You need to use a 5-6 mm drill. Recess the flange with a ten-millimeter tip into a pipe with a diameter of 100 mm and weld it.
- We are preparing the second pipe. Weld a flange to the second section of pipe. It should be 80 mm from the edge. This part of the pipe will be inserted into the muffler.
- Carefully lay mineral wool insulation into a pipe with a diameter of 100 mm. This is to combat noise reduction. To do this, roll the cotton wool along the diameter of the pipe and push it to the opposite side.
- Roll up the mesh and lower it inside the insulation that was inserted into the pipe. The mesh should fit onto the pipe with holes.
- Now you need to insert the flange with the pipe, which you prepared in advance, into the pipe with the short end. It needs to be recessed to a depth of 10 mm and welded.
- You can cut off the fastening elements from the old muffler and transfer them to the direct-flow muffler by welding them.
Alternative options
If you are interested in how to make a muffler quieter without losing precious horsepower, you can use a scheme that has been used in Chinese motorcycles for quite a long time. However, it is worth remembering that this option is only suitable for the production of mufflers for low-power motorcycles, whose performance does not exceed 40 hp. With. A pipe is inserted into the muffler body two-thirds of its length, the last 10 centimeters of which are covered with small holes according to the scheme described above. Having installed the inlet pipe, we are engaged in the outlet, which will be a pipe of a slightly larger diameter, inserted from the opposite side by two-thirds. It also remains to drill holes in 10 centimeters located closest to the motorcycle engine - such a muffler will represent a compromise between forward flow and the factory product.
If you know the structure of a motorcycle muffler, you can probably make a forward flow from an ordinary part. After opening the housing, you will see tubes that pass through special chambers, first to the end of the muffler, and then back and again to the exhaust pipe. These, as well as the motorcycle's catalytic converter, will need to be removed to achieve the desired effect. The perforated tube mentioned in the previous diagrams is inserted inside and wrapped with fiberglass. Of course, you can buy a special synthetic material used in the packing of original mufflers, but it will obviously cost more.
If you already know how to make a motorcycle muffler that fully meets your requirements, do not forget about fine-tuning the exhaust - for this you need to select the optimal diameter and position of the pipes, as well as the density of the holes. It is almost impossible to achieve an ideal result without using a special stand, so you will have to be content with approximate parameters obtained experimentally. In addition, after installing a different muffler, the motorcycle engine should be retuned. Modern injection engines will require the installation of new firmware, but carburetor motorcycles get by with a simple adjustment of the fuel system. Not every motorcyclist can do this kind of work, so it is quite possible that you will have to go to a specialized service center.
Independent work
Making a motorcycle muffler can be quite simple, but will it fully meet the requirements for it? Get ready for the fact that the first product you make with your own hands will require certain modifications and many hours of adjustments. However, practice shows that the second or third time it is possible to make a muffler for a motorcycle that initially meets all the required parameters. Sometimes it happens that it is not possible to make the required muffler for a motorcycle at all - this may be due to a lack of experience or certain design features of the equipment. In this case, it is better to buy a finished product from a well-known manufacturer or order the production of a direct flow from a real professional.
