Cowl

Cowl Mufflers Cowl® silencers feature a unique single spiral chamber design that allows a free flow of exhaust gas through a uniform cross-section throughout the entire spiral chamber.  As the exhaust gases pass through the spiral chamber, exhaust noise is progressively attenuated.  The benefits of the Cowl® spiral chamber are high sound attenuation, very low exhaust back pressure and a very small package size.  For information on Cowl sizes and styles available click here.

Cowl's Diagram
Typically, Cowl silencers are approximately 1/3 the physical size and ½ the weight of conventional cylindrical silencers, of similar performance

Vernatone

VERNATONE™

Builders and boaters requested these variations for specific engine or location requirements in a particular vessel. These mufflers also vary in size which influences the acoustical performance.

Vernalift

The Vernalift muffler was designed originally for small auxiliary propulsion engines installed near or below the water line in sailboats.

Vernatube

VERNATUBE™
