Applications We Serve
Application-specific mufflers, exhaust systems, and metal-formed components — engineered for the equipment you build.
CS Cosmos STIHL manufactures application-specific mufflers, exhaust systems, and metal-formed components for OEMs across outdoor power equipment — zero-turn and ride-on, handheld, battery-powered, lawn and yard, and stationary power platforms — engineered, finished, and assembled under one roof.
CS Cosmos STIHL has manufactured components for the outdoor power equipment industry since 1972. Across every platform we serve, we engineer and build the exact mufflers, exhaust systems, and metal-formed components your equipment requires — from prototype through full production, under one roof and one quality system.
