The Honda 18310-Z4V-801 Muffler (Arrester) is a genuine OEM replacement built for GX120, GX160, and GX200 horizontal shaft engines, as well as HS724 and HSS724 two-stage snow blowers. As a direct Honda OEM component, this muffler is produced to the same specifications as the original part it replaces, so installation is straightforward with no guesswork on fit. Verify your machine's serial number against the fitment table before ordering.
Key Features
- Integrated Spark Arrester — the built-in arrester screen captures and cools exhaust particles before they exit, an important feature for equipment operated near dry vegetation or in environments where open sparks are a concern
- Genuine Honda OEM Part — manufactured to Honda's exact exhaust specifications, ensuring correct backpressure, sound attenuation, and a drop-in fit with the original mounting points
- Broad Fitment Across Engines and Snow Blowers — designed for GX120, GX160, and GX200 horizontal shaft engines, including units powering the HS724 and HSS724 two-stage snow blowers
- Serial Number Verification Recommended — Honda updates exhaust components at production breaks, so confirm your unit's serial number against the compatibility table to ensure this is the correct muffler for your machine
- Exhaust Flow and Engine Performance — a cracked, corroded, or plugged muffler restricts exhaust flow and robs the engine of power; replacing a worn unit restores proper scavenging and keeps the engine running at its rated output
The muffler on a small engine performs two jobs: it dampens exhaust noise as combustion gases exit the cylinder, and — in this arrester-equipped version — it traps hot carbon particles before they leave the exhaust outlet. The arrester screen is the key difference from a standard muffler, making this component the appropriate choice wherever the risk of airborne sparks is a factor. When a muffler cracks, rusts through, or its arrester screen becomes clogged with carbon buildup, the engine loses back-pressure, runs louder, and can no longer contain exhaust debris — replacing it with a genuine Honda unit brings the exhaust system back to correct operation.
