Key Features
- Tier III Emissions Compliance — Engineered to meet Tier III exhaust emissions regulations, keeping the FS6600D floor saw compliant on restricted-access and indoor-adjacent work sites.
- High-Temperature Construction — Built from materials rated for sustained high-heat engine exhaust, maintaining structural integrity and sealing under the thermal demands of a heavy-duty floor saw.
- Genuine OEM Specification — Manufactured to Husqvarna's exact tolerances for exhaust flow, back-pressure, and mounting geometry — not a generalized fit, but a direct match for the FS6600D.
- Direct Bolt-On Replacement — Matches the original mounting configuration of the FS6600D, allowing straightforward removal of the worn unit and installation of this muffler without fabrication or adaptation.
- Exhaust Integrity Restored — A failed or cracked muffler allows uncontrolled exhaust gases to escape near the operator and engine bay. Replacing with this genuine part restores proper exhaust routing and sound attenuation.
The muffler channels exhaust gases away from the engine and directs them safely clear of the operator, while reducing noise levels to within acceptable operating ranges. On a Tier III-rated machine like the FS6600D, the muffler also plays a direct role in emissions compliance — a cracked, corroded, or incorrect muffler can cause the saw to fail emissions checks and generate excessive heat near adjacent components. Replacing a worn muffler promptly protects the engine, the operator, and the machine's regulatory standing on the worksite.
