Overview

Good Chamber Type Silencer:
Model M21

Expected Attenuation is 17 to 20 dBA

Use a model M21 in residential and light industrial areas where background noise is relatively high and constant and the need for higher degrees of silencing is minimal.

Example: In residential neighborhoods having high traffic or light industry with relatively constant background noise. Residents in these areas are typically accustomed to the noise or make some efforts to shield themselves from the ever present background noise. Use of an M21 can keep engine exhaust noise within existing levels.
