The Wacker Neuson Flex Exhaust Pipe G320 is a genuine OEM component designed for the G320 generator series, including Standard, Cold Weather, and Custom variants across T4, T4i, and Tier 4 Final configurations. As a direct OEM replacement, this part is manufactured to the exact specifications of the original, ensuring a correct, hassle-free installation on your G320 machine. It covers a wide range of G320 build variants — including Transport Canada-certified and Hertz-specification units — making it the go-to replacement for fleet operators and service technicians working across multiple G320 configurations. Keep your generator running cleanly and safely by replacing a worn or damaged flex exhaust pipe with the correct Wacker Neuson part.
Key Features
- OEM Exhaust Integrity: — Manufactured to original heat and vibration tolerances, ensuring the flex section absorbs engine movement without cracking or leaking exhaust gases.
- Direct Bolt-On Replacement: — Matches the original exhaust routing, flange dimensions, and flex length for a straightforward swap with no improvised adapters or modifications.
- Broad G320 Coverage: — Fits Standard, Cold Weather, and Custom G320 generator configurations across T4, T4i, Tier 4 Final, and Tier 4 Final Transport Canada variants, plus Hertz-specification units.
- Maintains Clean Exhaust Flow: — A sound flex pipe keeps exhaust routed safely away from the machine and operator; a cracked or failed flex section can allow hot exhaust gases to escape into the enclosure or work area.
- Emissions Compliance Assurance: — Correct exhaust routing is essential on Tier 4 Final and T4i-compliant generators; replacing a compromised flex pipe helps maintain the integrity of the engine's emissions system.
The flex exhaust pipe connects the engine's exhaust outlet to the main exhaust system on a mobile or stationary generator, acting as a vibration-absorbing link that prevents rigid metal-to-metal fatigue cracking. Its flexible construction allows the engine to move slightly under load without transmitting stress to the surrounding exhaust piping. When the flex section deteriorates — through heat cycling, corrosion, or physical damage — exhaust gases can escape at the joint, creating a potential hazard and reducing the efficiency of the emissions management system.
