The muffler is a weight component of the exhaust system of an automobile. Formally, there are resistance (shape), resistance (shape), compounding and so on. Among them, the resistive muffler is mainly composed of porous tubes and sound-absorbing fibers (sound-absorbing cotton). The sound absorption coefficient of the latter varies with the physical properties such as density and diameter. That is to say, the larger the fiber density, the smaller the diameter, the higher the sound absorption coefficient. The value of sound absorption coefficient is related to the effect of the muffler. Of course, there are many factors that affect the muffler's muffling effect, such as the circumference, effective length and cross-section area. The bigger the circumference and effective length, the better the muffling effect.

How does resistance exhaust work?

Resistive mufflers have porous tubes and sound absorption fibers. When exhaust gas contacts the fibers through the porous tubes, the latter generates vibration and heat energy due to friction and viscosity. Noise is transformed in this process, so it is also called sound absorption process.

Resistance muffler has the characteristics of small size, so most of the original drums like to use resistance. If you want to give full play to its silencing function, the installation position is generally relying on the direction of the engine. A large number of experiments show that the effect of resistive muffler on engine middle and high frequency noise suppression is better than that of medium and low frequency. In the same case, the performance of resistance exhaust is just the opposite to that of resistance exhaust.
