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.
