Multiquip 42448 Exhaust CAT to Muffler Assembly - OEM Replacement Part

This exhaust assembly connects the catalytic converter to the muffler on Multiquip ride-on power trowels, providing critical emission control and exhaust gas routing. As a complete CAT-to-muffler section, this component ensures proper exhaust flow, maintains emission compliance, and reduces engine backpressure for optimal performance during concrete finishing operations.

The exhaust system on ride-on trowels operates under demanding conditions with constant vibration, heat cycles, and exposure to concrete dust and moisture. Regular inspection of exhaust components is essential for maintaining engine performance and operator safety. Signs that this assembly may need replacement include visible cracks or holes in the tubing, excessive exhaust noise, exhaust leaks detected near the catalytic converter or muffler connection points, or failed emission testing.

This exhaust assembly is designed specifically for the HTXG6DF ride-on trowel equipped with a seat switch safety system. Proper exhaust routing and sealing are critical when operating in enclosed areas where ventilation is a concern.
