How to make a muffler on a car with your own hands: manufacturing instructions

In many cars, the components of the exhaust pipes are problematic. They often fail, burn out or rust. New car systems for silencing the sound of a running engine after replacement sometimes do not last a year, coming into disrepair. This situation pushes some motorists to the idea of ​​creating a muffler with their own hands using a more reliable and durable material for manufacturing. Agree, I do not want to spend almost every year on the purchase of exhaust pipes. You can also try to do so, to make the running car quieter.

The role of mufflers in the car

Exhaust pipe system, despite the seeming simplicity of purpose, performs several important functions, namely:

• significant reduction in the intensity of sound phenomena, arising from fuel combustion;
• lowering the temperature of the gases, initially have very high thermal performance;
• reducing the toxicity of exhaust gases.

That is, the muffler is needed not only for that, to make the car work quieter, although, essentially, this is its main purpose.

The self-made muffler can be made of improvised materials.

How the car's exhaust pipe works

Modern pipe systems, exhaust gases from the engine, at the same time transforming them, consist of several consecutive functional elements:

1. Corrugated pipes, depart directly from the exhaust manifold. These elements do not have a rigid structure, necessary for that, so that the vibration of the engine is minimally transmitted to the entire structure of the pipe.
2. catalyst, where the deactivation of the most environmentally and hygienically dangerous compounds takes place, formed by the combustion of hydrocarbons.
3. resonator, is a special extension in the passage of gases through the exhaust system. This is the primary inhibition of gases, where the pulsating flow becomes slower and smoother. The standard resonator is designed to dampen the pulsations of the exhaust of a certain frequency, characteristic of this engine.
4. muffler, where the exhaust finally loses speed and temperature due to dissipation. This formation has a rather complex structure, designed to disperse the gas flow as much as possible and absorb sound vibrations.

The quality of each structural element of the exhaust pipe depends not only on their design, but also by weight. The harder (thicker metal) the same muffler, the less he perceives all sorts of vibrations. That is, the sound of the exhaust becomes quieter.

Thin-walled exhaust pipes are not only short-lived, but also more rattling, themselves creating unwanted noise. This is also often the reason, that motorists seek to make a muffler with their own hands, using better quality material, than used in the manufacture of a serial manufacturer.

A method of self-manufacturing muffler for cars

To make a homemade device you will need an outdated car powder fire extinguisher. This model of homemade muffler is not only effective, but also tested many times, therefore deserves attention. For work, except for the fire extinguisher, the following materials and tools will be needed:

• two-inch steel (inner diameter) pipe or two of its segments;
• some elements of the old muffler;
• electric welding machine;
• welding electrodes (1,5-2,5 mm);
• small Bulgarian with cutting wheels for metal.
