Good silencing characteristics over a wide frequency range:
Model MUL
Expected Attenuation is 28 to 32 dBA
Designed for smaller engine applications, the MUL is available in pipe connection sizes 1" to 3 ½". Offering semi-critical grade silencing comparable to a model M31, an MUL is suitable for residential areas where background noise is present but not objectionable and engine exhaust noise is desired to match the ambient noise levels.
