Multiquip 45491 MRX Muffler - OEM Replacement Part for Ride-On Trowels

The MRX muffler controls exhaust noise and directs combustion gases safely away from the engine on Multiquip ride-on power trowels. This exhaust component is critical for maintaining OSHA-compliant noise levels on concrete finishing jobsites and preventing exhaust backpressure that can reduce engine performance and longevity. A failing muffler will exhibit increased noise levels, visible rust perforation, or rattling internal baffles that require immediate replacement to protect engine efficiency.

This muffler is engineered specifically for the heavy-duty operating conditions of ride-on trowel applications, where continuous operation at high RPMs and exposure to concrete dust and moisture demand robust exhaust system components. The LD6 and LD60 models feature Vanguard V-twin engines that rely on proper exhaust flow to maintain optimal power output during floating and finishing operations.

Compatible with the following Multiquip ride-on power trowel models:

• LD6
• LD60
