Good silencing characteristics over a
wide frequency range:
Comparable to the M31 for pipe thread sizes 1" to 3
½"
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. |
