4″ to 6″ Tip Style Sound Elimination Mufflers

Part Number: 39111 Categories: ,

CMI Sound Elimination Systems 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 85 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. This tip style muffler mounts directly to your transom and accepts 4″ soft wall exhaust hose. This tip transitions to a 6″ muffler can for higher HP applications.
