Multiquip 43140-23 Catalyst Muffler - OEM Replacement Part

The catalyst muffler is a critical emissions control and exhaust component that reduces harmful pollutants and noise levels on dual-fuel ride-on trowels. This OEM catalyst muffler ensures your equipment meets emissions standards while maintaining optimal engine performance and exhaust flow during concrete finishing operations.

Designed specifically for the STXDF ride-on trowel, this catalyst muffler works with both gasoline and liquid propane gas (LPG) fuel systems. The STXDF features a dual-fuel system that allows operators to switch between gasoline (14.5 gallon capacity, 87-89 octane unleaded) and liquid propane (33.5 lb. HD-5 capacity) without interrupting operation. The catalyst muffler handles exhaust from both fuel types while maintaining the unit's guaranteed sound pressure level of 96 dB(A) at the operator station and sound power level of 134 dB(A) per ISO standards.

This component is essential for proper engine operation and emissions compliance. Replace if you notice increased exhaust noise, reduced engine performance, or visible damage to the muffler housing.
