Key Features
- Genuine OEM Exhaust Construction — Built to Multiquip's original material and dimensional spec for the ST-45TDRM exhaust system, ensuring proper thermal performance and structural integrity under engine load.
- Direct Bolt-On Replacement — Matches the original mounting configuration of the ST-45TDRM, so installation follows the factory service procedure without fabrication or adaptation.
- Confirmed ST-45TDRM Fitment — Engineered specifically for the ST-45TDRM swing-tube concrete pump; verify EM98034 and VN#M065074 against your serial tag before ordering.
- Maintains Proper Back-Pressure Balance — A correctly fitted muffler preserves the engine's designed exhaust back-pressure, protecting combustion efficiency and engine output on a working concrete pump.
- Emissions and Noise Compliance — Replacing a damaged or failed muffler with this genuine OEM unit restores the exhaust system to its original noise attenuation and emissions performance profile.
The muffler is a core component of the engine's exhaust system, responsible for channeling hot exhaust gases away from the engine while dampening combustion noise to a safe and compliant level. On a concrete pump like the ST-45TDRM, the engine runs under sustained load during pumping operations, placing consistent thermal stress on the muffler body and mounting hardware. When a muffler cracks, corrodes, or the mounting fails, exhaust gases can escape before the silencing chamber, increasing noise levels and creating a potential heat hazard for operators and surrounding equipment. Replacing the muffler promptly with the correct OEM part — EM98034 — keeps the engine running at its intended operating conditions and the worksite environment safe.
