Custom Marine Mufflers Fabrication
Precision-Built Exhaust Silencing Systems for Marine Applications
Openex specializes in the custom fabrication of marine exhaust mufflers and silencers engineered for performance, durability, and acoustic control in demanding marine environments. Designed to handle backpressure, saltwater exposure, and high thermal loads, our mufflers are built to meet the acoustic and structural requirements of shipbuilders, naval designers, and offshore platforms.
Whether you require inline silencers for propulsion engines, generator mufflers, water-cooled configurations, or custom hybrid systems, Openex delivers heavy-duty, corrosion-resistant mufflers tailored to your vessel's specifications. From fishing fleets and ferries to offshore rigs and naval vessels, we build marine mufflers that perform reliably in the harshest conditions.
