3in Oxygen Sensor Reducer

The HEDMAN 3in Oxygen Sensor Reducer is a precision exhaust system component designed for vehicles requiring collector-to-downpipe transitions where inlet and outlet diameters differ. This reducer bridges the gap between a 3-inch inlet collector and a 2.25-inch outlet, making it suitable for various applications, including custom exhaust fabrication.

Constructed from heavy-duty steel with a natural (uncoated) finish, the 3in Oxygen Sensor Reducer features a 3-bolt flange connection for secure mounting. The integrated oxygen sensor bung with gasket ensures compatibility with modern emissions monitoring systems, while the tapered design minimizes turbulence and supports clean combustion readings.

This reducer is ideal for fleet maintenance teams, custom exhaust fabricators, and vehicle technicians working on performance or emissions-compliant builds where diameter matching is essential. Its compact design allows for installation in tight engine bay environments while maintaining structural rigidity in high-vibration applications.
