Advice 1: How to make a quiet muffler

Muffler is required for reducing the noise produced by the flow of exhaust gases, effectively blocking their path. And ideally obstacles for exhaust gases from the cylinder should not be.

To begin the fight against excessive noise produced by the vehicle, start the offensive on all fronts. Before you make the plunge, you should clearly imagine the work of the exhaust system of a car engine. After the engine and exhaust system are balanced with each other so as not to interfere with each other. Disturbance of this balance may lead to improper engine operation.
2
Use the simplest method of noise reduction – set "Bank" (as motorists called for more end-muffler). It is made from the housing, through which passes a pipe with apertures. The case is filled with a filler of heat-resistant fiber, fixed fine mesh. It is installed between the catalyst and the standard muffler.
3
Cut out the section of pipe between the catalyst and silencer to the required length corresponding to the length of "banks". Remove the exhaust muffler. Install and attach the "Bank" to the resonator, using clamps and asbestos sheet for sealing the joint.
4
Install muffler seat docked with a "jar" using, again, the clamps and asbestos sheet for sealing the joint. When installing "banks" or the end of the silencer must be thoroughly sealing the joints of tubes of heat-resistant asbestos in order to prevent breakthrough of the exhaust gas, which will create increased noise level.
5
The additional effect of noise reduction will give replacement of the resonator mounted on the car by the manufacturer, on the same "Bank" with a heat-resistant filler. The replacement of the resonator can be made on the same technique.
6
You can try to use another method of noise reduction is to replace the exhaust manifold at manifold of special design. Unfortunately, this method relates to the difficulty of purchasing the spare parts for specific car brands.

Advice 2: How to make a homemade silencer

About the engine work is judged by the noise of gases from the exhaust pipe. The factory your car was fitted with its exhaust system. Exhaust manifold, connecting pipe, muffler – everything is calculated. To improve this design alone is almost impossible. But since the exhaust system works in harsh conditions (high temperatures, high pressure, aggressive oxide processes), its elements and in particular the silencer, fail earlier than other systems of the car.

And here you are standing before a dilemma: to purchase a new muffler at the parts store or try to do it with their hands. Purchase somewhat alarming. It is unclear what firm made the silencer what material, and workmanship often causes mistrust. There is a desire to try to make this simple item at home. Especially that replacement for the standard straight-through muffler will help to increase the engine power.
2
External dimensions and mounting elements in front of your eyes. Measure them and purchase the basic materials for the manufacture of a new silencer. Body, to increase its service life, it is better to make stainless steel. Flange use old, cut them with a angle grinder. The connecting pipe and adjust to the new made from pipe of suitable diameter and convex pattern.
3
Now decide what you want to get the result of the muffler. It could be a exhaust system which:
- Does not reduce engine power;

- Reduces the engine power while reducing noise when it is working.
4
In the first case, the necessary flow muffler device without any energy-absorbing chambers. Its principle is freed the faster the engine cylinders from the exhaust, the less the effort required for their removal, the greater the power received at the output. Following a number of simple steps, you will receive the "roaring" exhaust, indicating the power of your car.
5
The second option for lovers of a quiet life. If you avoid conflict relationships with others, do it in the muffler stuffing. It is known that noise is vibrations in the air caused by the speed of the gases removed from the muffler into the atmosphere. In order to lower it substantially and thereby reduce the noise level, you need speed to lower the pressure of gases and their speed from the moment of their entry into the muffler until the removal of the exhaust pipe. To do this, the pipe running to the muffler, make a hole and fasten the partitions, which will divide the space of the muffler on the camera.
6
The exhaust gases entering the silencer through the holes in the pipe, fill the volume of the first chamber, i.e. expand. Since the volume of the chamber is restricted gases through the same holes in the tube fall into the following chamber. The pressure decreases because of the energy expended to increase, and then decrease in the first chamber. And so from chamber to chamber to exit the muffler.

The speed of the exhaust gases will be reduced, which will lead to a significant reduction of noise when they are released into the atmosphere.

Advice 3: How to fix a silencer

If the muffler starts to rattle and Bang on the car body, so damaged fixing it. To avoid unnecessary vibration driving the car on a pit or hoist and run a diagnosis on the muffler. In that case, if the collapsed mounting, remove the muffler, weld it again and reinstall it. If the incident occurred on the road, tied the muffler with wire.
How to fix a silencer
You will need
  • key set, welding machine, mild steel wire, a set of rubber stops
Instruction
1
With the disengagement of the muffler from the mounting, continue driving with caution to the elements of vibration from damaging the vehicle body. Driving the car on the pit and determine what elements of the muffler collapsed. Weld them and then reinstall. Note, however, that the muffler is mounted on a special rubber suspension, which should be replaced, because with the increased vibration they can break. If the mounting entire obtyanite the bolts that fix the muffler.
2
The complete destruction of the silencer, take it off, whirling attachment. Be careful not to damage the parts that are around him. If the nut is stuck so that they cannot remove the key, gently rock the tube from side to side, if that does not work, cut the bolts.
3
When installing be sure to use new rubber hangers, gaskets and clamps and mounting bolts and nuts. When tightening clamps, control efforts to the muffler pipe has not been deformed. Assembling the muffler, use a special sealant compounds, wouldn't that put all the gaskets. This will ensure quiet operation of the engines and will make it impossible for any exhaust leaks.
4
Be careful, if the sealant gets inside the exhaust pipe and lambda probe, he definitely will bring it down. After installation make sure all parts of the muffler installed horizontally, without bias, otherwise the tightness can not be achieved.
5
In case if the muffler will come off on the road, away from populated areas, carry a piece of soft steel wire, will be enough length to 1 m. Secure the muffler in place, cut off the mounts with wire. This will not eliminate vibration but will prevent further degradation of the silencer. As soon as possible, immediately head to the repair.

Advice 4: How to make a silencer

If the damage of the muffler of the car before the owner raises the question: to change the muffler completely or to rebuild the old one. If the damage muffler is strong, the weld will not help to rebuild it, and have to spend money to replace the part.
How to make a silencer
You will need
  • 1. Welding machine,
  • 2. sandpaper,
  • 3. white spirit,
  • 4. cold welding.
Instruction
1
Brewing muffler is possible only in the case when the violation of its integrity occurred when hitting an obstacle. Can be repaired in many garage workshops, elimination of small cracks or burnout is inexpensive, and if you are confident, you don't have the necessary equipment – it is better to consult the experts. If the hole in the muffler was the result of corrosion, welding, most likely, will not help. In this case, the metal around the hole is also typically thinned to the limit. Can sometimes help a patch of sheet metal that are welded to the power hull seams (these seams are thick and resist rust longer).
2
Independently carry out repairs to the muffler by welding is only if you have a viewing hole and semi-automatic welding and experience welding on it.
3
Caribaea clean the surface from residues and rust. Before you begin welding, be sure to turn off the vehicle ignition, disconnect the battery – this is required for security purposes. After welding, remove the slag, gently cleaning it with sandpaper.
4
You can use cold welding. For the average motorist it's the most affordable method. Clean the surface of the muffler around the hole or cracks with sandpaper, remove all contamination and degrease with acetone, white spirit or other similar means. Prepare a cold weld according to the instructions that comes with it, and apply the weld on the hole, carefully concealing all imperfections. Let the welding zastynut.
5
In any case, be prepared for the fact that brewing the muffler will fail or the result will leave much to be desired. It is likely to occur in the muffler new holes next to the weld. Much safer to buy a new muffler and install it to replace the old.
Note
Once the cars were done at all without mufflers. Spewing smoke from the exhaust pipes short, they produced terrible noise, absolutely do not correspond to the modest capabilities of those engines. If the muffler is damaged mechanically (e.g. broken on stone), then there is a good chance to save him simply brew gas welding like a normal pipe.
Useful advice
In the presence of minor burnouts and other damage, the muffler can be repaired completely. A good and reliable method of welding. But you can not always find staff and professional welder. Particularly problematic to brew a burnout, if the metal is very loose and nothing to weld patch. In this case, extend the life of the muffler will help the chemistry.
