The Wacker Neuson is a genuine OEM Med Muffler designed for the G100 and G120 series T4i generators, including Custom, Standard, Cold Weather, and Hertz configurations. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original component, ensuring a correct, hassle-free installation. This muffler covers a broad range of G100 and G120 variants, making it the go-to replacement for fleet operators and service technicians running multiple generator configurations.

Key Features

  • OEM Exhaust Integrity — Genuine Wacker Neuson construction ensures correct exhaust flow restriction and backpressure calibration for T4i-compliant engine performance.
  • Bolt-On Replacement — Matches original mounting points and port dimensions on G100 and G120 generators for a straightforward swap with no fabrication or adapters.
  • Broad G-Series Compatibility — Fits eight distinct G100 and G120 generator models spanning Custom, Standard, Cold Weather, and Hertz T4i variants.
  • Engine Protection — A properly functioning muffler controls exhaust temperature and sound output; a cracked or failed unit can lead to excessive heat buildup, increased noise levels, and engine stress.
  • Emissions Compliance — Purpose-built for Tier 4i regulated generators, this muffler supports proper exhaust treatment to help the machine meet applicable emissions requirements.

A muffler channels hot exhaust gases away from the engine and reduces the noise produced during combustion. On a portable generator like the G100 or G120, it also plays a role in maintaining the correct exhaust backpressure that the engine is tuned to run against — too little or too much resistance can affect power output and fuel efficiency. When a muffler cracks, corrodes, or develops a leak, exhaust gases can escape in unintended directions, raising heat levels around the unit, increasing noise beyond acceptable limits, and potentially triggering emissions non-compliance on regulated T4i machines.
