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.

These mufflers are engineered to reduce sound without restricting the exhaust or creating unwanted backpressure, which can inhibit the engine from reaching peak performance power. Mufflers can be installed on any exhaust system with tailpipes ranging from four to six-inches in diameter, which covers the full range of inboard or stern drive-powered recreational and performance boat applications up to 1200 horsepower.

CMI Sound Elimination Systems 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.

Clamp-on options include a 4” model to fit tip-style tailpipes ; a 4.5 inch model to fit thru-transom tailpipes; and a 5-inch model for larger tailpipe diameters primarily used with CMI Big Tube Racine Header Systems.

The 5-inch muffler can also be retro-fitted into 5 and 6-inch outside diameter tailpipes to accommodate larger horsepower applications. This option is also available to OEM boat builders who order mufflers installed during the tailpipe manufacturing process for an inconspicuous appearance on the transom.
