Stationary Power Unit Components
Mufflers, exhaust systems, and metal-formed components for generators, pumps, and stationary engine packages.
CS Cosmos STIHL manufactures OEM mufflers, exhaust systems, and stamped components for stationary power units — portable and standby generators, pumps, and stationary engines — engineered for sound attenuation, heat management, and continuous-duty endurance, then finished and assembled in-house.
Stationary power equipment — portable and standby generators, pumps, and engine-driven packages — runs longer and hotter than handheld or ride-on equipment, often in residential or noise-sensitive settings. The exhaust system has to attenuate sound, manage continuous-duty heat, and resist corrosion across years of service. CS Cosmos STIHL engineers and manufactures stationary-power mufflers, exhaust systems, and stamped components from your drawings, finished and assembled in-house.
What We Build
-
Generator and genset mufflers and exhaust assemblies
-
Industrial, residential, and critical-grade silencers
-
Exhaust tubing, flex connectors, brackets, and heat shields
-
Stamped enclosure panels, guards, and engine-base components
-
Welded subassemblies, finished and assembled in-house
Engineered for Continuous Duty
Stationary applications demand exhaust that performs over long run cycles. We tune mufflers to the sound class the application requires — from standard industrial attenuation to residential and critical-grade silencing — while controlling backpressure so the engine meets its power and fuel targets. Continuous-duty heat is routed and shielded to protect surrounding components and enclosures, and material and finish selection is matched to outdoor, standby, and high-temperature exposure.

One Source for the Whole Exhaust System
Forming, deep drawing, welding, finishing, and assembly under one roof means an OEM gets a complete, finished stationary-power exhaust system and the surrounding stamped components from a single accountable partner. That consolidation reduces fitment and inspection burden, protects program timing, and keeps a single quality system accountable for the whole assembly.
Frequently Asked Questions
Does CS Cosmos STIHL make generator mufflers?
Yes. CS designs and manufactures custom mufflers and exhaust assemblies for portable and standby generators, pumps, and stationary engines, built to your prints.
Can CS supply critical-grade or residential silencers?
CS manufactures mufflers across attenuation classes; confirm the specific silencer grades available for your sound and application requirements.
Will the exhaust arrive finished and assembled?
Yes. In-house finishing and electromechanical assembly mean systems ship finished and weld-complete, ready for the OEM line.
What materials suit continuous-duty stationary exhaust?
Aluminized and stainless steels are selected during DFM to balance corrosion resistance, heat tolerance, and cost for the duty cycle.
What volumes does CS handle for stationary power?
CS scales from prototype through high-volume production, with capacity planning developed across decades of OEM programs.
