Key Features

• Genuine OEM Construction — Built to Multiquip's exact specifications for the QST30-G5 platform, ensuring proper exhaust flow and acoustic dampening at 1000 kW output levels.

• Confirmed QST30-G5 Fitment — Verified for use with the Multiquip QST30-G5 Cummins-powered generator series; check your model code before ordering.
• Exhaust Integrity at High Output — A properly functioning muffler maintains correct exhaust backpressure and noise attenuation; a failed or compromised unit can affect engine efficiency and site noise compliance.
• Emissions and Noise Compliance Support — The correct OEM muffler helps maintain exhaust system performance within the parameters the engine and enclosure were originally designed to meet.

A box muffler is a critical component of the generator's exhaust system. Its job is to reduce the noise and pressure pulses produced by combustion gases exiting the engine, channeling exhaust safely away while keeping sound levels within acceptable limits. On a high-output platform like the QST30-G5, the muffler must also withstand sustained high-temperature and high-volume exhaust flow — a worn, cracked, or improperly fitted muffler can increase noise output, cause exhaust leaks, and place added thermal stress on surrounding components.
