Strict noise ordinances are being enforced all around the country…CMI Sound Elimination System mufflers and transom tips offer proven sound reduction technology that enables most boaters to operate their performance boats in areas where sound emissions are restricted.

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.

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.

CMI offers both baffled and non-baffled stainless steel transom tips to fit most marine engine installations.
