Sound Elimination Mufflers

CMI Sound Elimination System mufflers offer proven sound reduction technology that enables boaters to operate their performance boats in areas where sound emissions are restricted. This system should reduce sound emissions to levels as low as 86 decibels (dB) in many applications, which is below most sound emission regulations.

The mufflers are engineered to reduce sound without restricting the exhaust or creating unwanted backpressure, which can inhibit the engine from reaching peak performance power.

CMI Sound Elimination System mufflers are made from 304 series stainless steel, and have fewer moving parts than competitive models to ensure long-lasting durability and reliability for nearly any application.

  • Available in both transom mount and clamp on ranging
    in sizes from 4" to 6"
  • Available in a polished finish
  • Results may vary, but most experience a drop in sound
    emission levels to 86 decibels (dB)
