Multiquip 23725-12 Catalytic Muffler Kit - OEM Replacement Part

This catalytic muffler kit provides exhaust emission control and noise reduction for Multiquip ride-on power trowels equipped with dual-fuel engine systems. Designed specifically for liquid-cooled 31 hp Kubota WG972 engines that operate on both gasoline and liquid propane gas (LPG), this complete kit ensures your trowel maintains compliance with emission standards while operating at optimal performance levels.

The catalytic muffler assembly is a critical component that converts harmful exhaust gases into less toxic emissions while dampening engine noise during concrete finishing operations. Regular inspection of the muffler system is essential, particularly in high-hour commercial applications where exhaust system integrity directly impacts operator safety and equipment compliance. Signs that replacement may be needed include excessive exhaust noise, visible damage or corrosion, reduced engine performance, or visible exhaust leaks at connection points.

This OEM kit includes all necessary components for proper installation on compatible dual-fuel ride-on trowel models.
