Cosmos Building


Our Philosophy

Cosmos Manufacturing has dedicated itself to achieving the highest standard of excellence for over 40 years. Through this commitment, Cosmos has succeeded in meeting and exceeding the needs of its customers with unsurpassed values and innovation.

Since 1972, we have developed innovative solutions, designed to help customers improve the quality of their products.

Cosmos has the capacity to serve any customer's needs. While our main focus is in the design, development, and manufacture of high volume quality mufflers and exhaust systems, for 2- and 4- cycle engines, we also provide a wide range of metal stampings for manufacturing and process industries.

By continuously increasing our in-house capabilities, Cosmos offers a full range of services to our customers.


Our History

Cosmos opened its doors in 1972 under the name Cosmos Tool & Die and changed its name to Cosmos Manufacturing, Inc. in 1997.  We started operations as a tool and die shop, but within the first year, Cosmos responded to customer demands to provide metal stamping services.  In 1973, we began a metal manufacturing services program that continues to grow in technology and volume to this day. In 1976, Cosmos hired its first full-time engineering designer; today we have a full staff of engineers, designers and programmers.

Seeing the success of its engineering, tool and die, and manufacturing departments, Cosmos began a program in 1994 to provide testing and analysis services to its large customer base.  Sound testing and analysis was the first to come on board.  Soon to follow were emissions testing in 1996 and durability testing in 2003.

Throughout its early years, Cosmos began to draw the attention of the lawn and garden industry, soon specializing in the manufacture of mufflers and components for small to medium-sized engines. We quickly joined the ranks of other major international manufacturers and today are one of the top manufacturers of mufflers for 2 and 4 cycle engines. In 1998, with the new clean air policies of the European community on the horizon, Cosmos was the first company to develop a catalytic element.  In 2012, Cosmos shipped over 10 million mufflers; about half of these were catalytic.  Our products are used all over the world in products designed for both professional and household consumers.
