Key Features

• Genuine OEM Exhaust Integrity — Manufactured to the same specification as the original assembly, maintaining correct exhaust flow path, back-pressure characteristics, and connection geometry for the QST30-G5.
• Direct-Fit Assembly — Engineered to mount to existing exhaust ports and hardware points on the QST30-G5 without rework, aligning with original bolt patterns and outlet orientation.
• Confirmed QST30-G5 Fitment — Verified for Multiquip QST30-G5 generator equipment; always cross-reference your unit's model code before purchase.
• Sustained Engine Efficiency — A properly functioning exhaust assembly allows the Cummins QST30-G5 engine to expel combustion gases efficiently, protecting power output and engine temperature management under continuous load.
• Emissions and Compliance Integrity — Replacing a failed or damaged exhaust assembly with a genuine OEM unit helps maintain the emissions compliance profile the generator was certified to meet at manufacture.

The exhaust assembly on a large industrial generator like the QST30-G5 collects and routes hot combustion gases away from the engine, directing them safely out of the enclosure or exhaust stack. A correctly functioning assembly maintains the designed back-pressure balance the Cummins engine relies on for rated power output and fuel efficiency — too much restriction or leakage at any joint disrupts this balance. When the assembly cracks, corrodes, or the connections loosen, exhaust gases can escape into the enclosure, create excessive heat buildup, trigger fault conditions, or cause the engine to run rough under load.
