Multiquip 21451 Muffler HHN ACS 34VTD - OEM Replacement Part

This muffler is an essential exhaust system component designed specifically for Multiquip power trowels, reducing engine noise to OSHA-compliant levels while directing hot exhaust gases safely away from the operator and equipment. Engineered for the demanding conditions of concrete finishing work, this muffler withstands high temperatures and continuous vibration while maintaining optimal engine backpressure for proper performance.

A failing or damaged muffler can result in excessive noise, reduced engine efficiency, and potential safety hazards on the job site. Signs that replacement is needed include visible rust-through, cracks, loose mounting, increased engine noise, or exhaust leaks. Regular inspection of the muffler and its mounting hardware is critical for maintaining safe working conditions and compliance with workplace noise regulations.
