The Wacker Neuson Muffler Complete is a genuine OEM exhaust assembly designed for DPU45Yeh US and DPU40Yeh US reversible plate compactors. Sourced directly from Wacker Neuson, this complete muffler assembly ensures an exact match to the original component it replaces — no guesswork, no fitment concerns. As a genuine OEM part, the is manufactured to the same specification as the unit installed at the factory, so you can restore full exhaust performance with confidence. Compatible with both the DPU45Yeh US () and DPU40Yeh US () machine configurations, this is the correct replacement when the original muffler is cracked, corroded, or no longer sealing properly.
Key Features
- OEM Exhaust Integrity — Cast and assembled to Wacker Neuson's original exhaust flow specifications, maintaining correct back-pressure for the Yanmar engine used in these compactors.
- Complete Assembly, Ready to Install — Supplied as a full muffler complete unit, so all components arrive pre-assembled and bolt directly to the engine exhaust port without sourcing separate sub-components.
- Confirmed Fitment for DPU Yeh US Models — Verified for the DPU45Yeh US and DPU40Yeh US reversible plate compactors, covering both machine configurations in this series.
- Restores Full Sound Attenuation — A failed or cracked muffler increases exhaust noise beyond acceptable operating levels and can direct hot gases toward operator or machine components; this replacement restores proper noise and heat management.
- Emissions and Safety Compliance — A compromised exhaust assembly can affect emissions output and expose operators to exhaust gases; a genuine OEM replacement ensures the exhaust system performs as originally certified.
The muffler on a plate compactor collects and channels exhaust gases away from the engine, dampening combustion noise and directing hot exhaust safely away from the machine and operator. A functioning muffler also maintains the correct exhaust back-pressure that the engine is tuned to operate with — too little resistance from a cracked or missing muffler can affect engine efficiency and throttle response. When a muffler corrodes, cracks, or loses its mounting seal, exhaust noise increases sharply, hot gases can damage surrounding components or create a burn hazard, and the machine may fall out of compliance with jobsite noise and emissions requirements.
