Husqvarna 574031502 Muffler Kit with Catalyst

Product Description

The HUSQVARNA 574031502 is a muffler kit with an integrated catalyst designed as a direct OEM replacement for Husqvarna outdoor power equipment. The muffler routes exhaust gases away from the engine and reduces noise during operation. The catalytic element in this kit helps reduce exhaust emissions by chemically converting combustion byproducts before they exit the exhaust port. This kit is installed by small-engine technicians and qualified service professionals who maintain Husqvarna handheld and walk-behind equipment.

This muffler kit with catalyst is used in Husqvarna lawn and garden power equipment applications. It is suited for residential and light commercial maintenance scenarios where the original muffler or catalyst component has failed, cracked, or become clogged with carbon deposits. The kit format includes the necessary components for a complete muffler replacement rather than a partial repair.

Key Features

• Integrated catalyst reduces exhaust emissions during equipment operation
• OEM replacement kit includes components for a complete muffler service
• Designed to restore original exhaust flow and noise attenuation
• Direct-fit replacement eliminates the need for fabrication or modification

Compatibility

Installation Notes

Installation should be performed by a qualified small-engine technician. Allow the engine and existing muffler to cool completely before beginning removal, as exhaust components retain heat and can cause serious burns. Disconnect the spark plug wire before servicing the muffler to prevent accidental engine start. Follow applicable safety and emissions guidelines for the equipment type when reassembling exhaust components.
