M22 Residential Chamber Exhaust Silencers

20 to 25 dBA Noise Reduction

The M22 is engineered for residential and light industrial areas where background noise is relatively high and constant. The need for higher degrees of silencing should be minimal, keeps engine exhaust noise within existing levels.

Typical application: Internal combustion engine exhausts in neighborhoods having high traffic or light industry with relatively constant background noise. Residents in these areas are typically acustomed to the noise or make some efforts to shield themselves from the ever present background noise.
