The Multiquip 2773011101 Muffler Spark Arrestor is a genuine OEM component designed for G-2.9R, GA-2.9R, and QP-2TE series equipment. Sourced directly from Multiquip, this part meets the exact design and material specifications of the original, ensuring a correct, trouble-free installation. It is confirmed compatible with G-2.9R portable AC generators, GA-2.9R super-silent generators, and QP-2TE trash pumps. When your existing muffler or spark arrestor is damaged, cracked, or missing its screen, this is the direct replacement to restore proper exhaust function and compliance.
Key Features
- Genuine OEM Construction: — Fabricated to Multiquip's original material and dimensional specifications, so exhaust backpressure and engine tuning remain within the designed operating range.
- Integrated Spark Arrestor Screen: — The built-in arrestor screen traps and extinguishes hot exhaust particles before they exit the outlet — an essential feature for operation near dry vegetation or on regulated worksites.
- Direct Bolt-On Replacement: — Engineered to match the original mounting configuration on G-2.9R, GA-2.9R, and QP-2TE units, so installation uses the existing hardware and mount points without rework.
- Protects Engine Performance: — A properly sealed muffler maintains correct exhaust flow; a cracked or deteriorated unit can cause erratic engine running, excessive noise, and increased exhaust temperatures.
- Regulatory Compliance: — Spark arrestors are required by law in many US states and on federal lands. Replacing a worn or missing arrestor screen with this OEM unit helps keep your equipment legally operable where open-flame restrictions apply.
- Broad Fitment Across Multiple Equipment Types: — A single part number covers generators and trash pump applications across the G-2.9R, GA-2.9R, and QP-2TE model lines, simplifying reorder and inventory.
The muffler and spark arrestor assembly serves two roles: it quiets exhaust noise produced by the engine and captures any hot carbon particles or sparks before they leave the exhaust outlet. The spark arrestor screen — a fine metal mesh integrated into the assembly — is what makes this unit essential on regulated or fire-risk worksites, as uncaptured sparks from a small engine can ignite dry grass or debris. When the muffler body cracks, the mounting flanges corrode, or the arrestor screen collapses or burns through, exhaust leaks past the assembly, engine sound increases noticeably, and the machine may fail a worksite safety inspection.
