Wacker Neuson 5200004105 Flex Exhaust Pipe G70 T4I

The Wacker Neuson Flex Exhaust Pipe G70 T4I is a genuine OEM exhaust component designed for the G70 portable generator series. This direct factory replacement fits the full range of Tier 4 Final G70 configurations, including the Custom T4i, Standard T4i, Cold Weather T4i, Extended Run T4i, Hertz T4i, and URI HVAC variants. As a genuine Wacker Neuson part, the is manufactured to the exact dimensions and material specifications of the original, ensuring correct alignment with the exhaust system and a sealed, leak-free installation. Keep your G70 generator running cleanly and safely by replacing a cracked or deteriorated flex section with the correct OEM component.

Key Features

• OEM Flex Section Integrity — Manufactured from the same flexible metallic material as the original, providing the correct vibration absorption and heat tolerance required in the G70 exhaust path.
• Direct Bolt-On Replacement — Matches the original pipe geometry and end connections, allowing a straightforward swap into the existing exhaust routing without reworking mounting hardware.
• Broad G70 T4I Coverage — Confirmed fitment across Custom, Standard, Cold Weather, Extended Run, Hertz, and URI HVAC configurations of the Tier 4 Final G70 generator.
• Maintains Exhaust Seal and Flow — A failed or cracked flex section allows exhaust gases to escape before the outlet, reducing generator efficiency and creating a hazardous working environment around the unit.
• Exhaust Integrity and Operator Safety — A properly sealed exhaust path is critical on enclosed or semi-enclosed job sites; this genuine OEM part ensures combustion gases are routed fully away from the operator and surrounding equipment.

The flex exhaust pipe serves as a flexible transition section within the G70 generator's exhaust system, absorbing vibration and minor movement between rigid exhaust components to prevent stress cracking and fatigue failures downstream. Its flexible construction allows the exhaust system to accommodate engine movement during operation without transferring load to fixed pipe joints or the muffler. When this section cracks, collapses, or corrodes through, exhaust gases can escape into the engine compartment or operator area, and the loss of back-pressure integrity can affect engine performance and emissions compliance on Tier 4 Final certified equipment.
