The Wacker Neuson Muffler is a genuine OEM component designed for the BFS series petrol floor saws, including the BFS 1345B, BFS 130RM, BFS 130R, BFS 1350L, BFSX 130RM, BFSX 130R, BFS 1345BZ, and BFS18D. Sourced directly from Wacker Neuson, this muffler matches the original specification for correct fitment and consistent exhaust performance. It is a direct replacement for the factory-installed unit, making it the straightforward choice when the existing muffler is cracked, corroded, or no longer sealing properly.
Key Features
- OEM Exhaust Specification — Manufactured to Wacker Neuson's original thermal and acoustic ratings, ensuring exhaust back-pressure stays within the engine's designed operating range.
- Direct Bolt-On Replacement — Matches the original mounting flange and port dimensions of the BFS series floor saws for a straightforward swap with no reworking of exhaust connections.
- Broad BFS Series Compatibility — Confirmed fitment across multiple BFS and BFSX floor saw models, including the BFS 1345B, BFS 130RM, BFS 130R, BFS 1350L, BFSX 130RM, BFSX 130R, BFS 1345BZ, and BFS18D.
- Engine Protection Against Exhaust Damage — A properly sealed muffler prevents hot exhaust gases from escaping at the manifold joint, protecting surrounding components from heat stress and premature wear.
- Exhaust Emission Compliance — As a genuine OEM part, this muffler maintains the engine's certified exhaust output, which matters on controlled worksites with emissions or noise requirements.
The muffler on a petrol floor saw routes combustion exhaust away from the engine, reduces noise to an operable level, and controls the back-pressure that affects engine efficiency. When a muffler cracks, corrodes, or loses its internal baffling, the engine can run rough, overheat in the exhaust zone, and produce excessive noise — all of which shorten engine life and make the machine harder and less safe to operate. Replacing a failed muffler promptly restores normal engine breathing and keeps the saw running at its intended power output.
