The Wacker Neuson Exhaust Pipe Doc Upper G70 T4I is a genuine OEM component designed for the G70 Generator series, including Custom T4i, Standard T4i, Cold Weather T4i, Extended Run T4i, Hertz T4i, and URI HVAC configurations. As a direct OEM replacement, is manufactured to the same specifications as the original part, ensuring a proper installation with no guesswork on fitment. This part ships as a direct application-specific component engineered for the G70 T4i platform's diesel oxidation catalyst (DOC) exhaust system.

Key Features

  • OEM Exhaust System Integrity — Manufactured to the same material grade and dimensional tolerances as the original, maintaining correct exhaust flow and sealing through the DOC upper section.
  • Direct-Fit for G70 T4i Generators — Engineered specifically for the G70 T4i exhaust assembly; connects directly to the existing DOC system without reworking surrounding components.
  • Broad G70 Series Coverage — Compatible with Custom T4i, Standard T4i, Cold Weather T4i, Extended Run T4i, Hertz T4i, and URI HVAC variants of the G70 Generator.
  • Emissions System Performance — A correctly fitted upper DOC exhaust pipe maintains proper back pressure and exhaust routing, keeping the Tier 4i emissions system functioning as designed.
  • Regulatory Compliance — Part of the Tier 4i after-treatment exhaust path; using the correct OEM pipe helps ensure the machine remains compliant with EPA Tier 4i emissions requirements.

The upper DOC exhaust pipe is a structural and flow-critical section of the diesel oxidation catalyst exhaust assembly on Tier 4i-equipped generators. It routes exhaust gases through the after-treatment system, allowing the DOC to reduce harmful emissions before gases are expelled. A cracked, corroded, or poorly sealed upper pipe can cause exhaust leaks, elevated back pressure, and failure of the emissions system — potentially triggering fault codes, derated power output, or regulatory non-compliance on the G70 T4i platform.
