Confirm your model number before ordering to ensure this is the right fit for your machine.
Key Features
- Genuine OEM Exhaust Sealing: — Manufactured by Wacker Neuson to original material and dimensional tolerances, ensuring proper exhaust gas containment and backpressure characteristics specific to this engine configuration.
- Direct Bolt-On Replacement: — Engineered to match the original mounting points and exhaust outlet position, so installation aligns with the existing hardware without modification to flanges or brackets.
- Broad ML440 and MG5 Coverage: — Compatible with multiple ML440 Light Tower and MG5 Portable Generator configurations, including MG5d models, covering a wide range of serial-specific variants under a single part number.
- Protects Engine Performance: — A correctly functioning muffler maintains proper exhaust flow and backpressure; a cracked, corroded, or blocked muffler can cause power loss, overheating, and premature engine wear.
- Exhaust Safety Compliance: — Replacing a damaged muffler with a genuine OEM assembly helps contain hot exhaust gases and reduces the risk of exhaust leaks near fuel components or operator areas on light towers and generators.
The muffler assembly is responsible for directing combustion exhaust gases away from the engine while reducing noise output to an acceptable operating level. It works by channeling hot exhaust through a series of internal chambers that dissipate sound energy before the gases exit the unit. When a muffler cracks, corrodes, or becomes blocked, exhaust restriction increases — causing the engine to run hotter, lose power, and potentially sustain internal damage over time.
