Reducer 2.25in OD 2in ID

The Schoenfeld Reducer 2.25in OD 2in ID is a precision exhaust pipe adapter designed for builders and mechanics who need to step down larger diameter exhaust tubing to smaller piping within custom exhaust systems. This 5-inch long reducer serves as a critical transition component in performance exhaust builds, custom headers, and manifold-to-pipe connections where diameter mismatches occur. Whether you're fabricating a street machine, race car, or restoration project with modern emissions equipment, this stepped reducer allows seamless flow transitions while maintaining structural integrity and exhaust scavenging efficiency.

Manufactured from durable steel in natural finish, the Reducer 2.25in OD 2in ID features a tapered design that gradually transitions from 2.25-inch outer diameter down to 2-inch inner diameter across its 4.5-inch length. The stepped geometry minimizes turbulence and flow separation, which is essential for maintaining backpressure characteristics and avoiding horsepower loss. At just 0.518 lbs, it's lightweight enough for tight engine bays while remaining rigid enough to withstand thermal cycling and vibration common in performance applications. The steel construction naturally resists corrosion from exhaust heat cycling, though ceramic or high-temp coating can be applied if additional protection is desired.

This reducer is ideal for fabricators and DIY builders stepping down from 2.25-inch primary tubes to 2-inch secondary piping, or when adapting aftermarket headers to OEM or custom muffler inlet sizes. It's commonly used in street rod exhaust systems, LS engine swaps, and vintage car restorations where modern emissions components require pipe size compatibility. Installation is straightforward: weld or clamp the reducer between larger and smaller diameter sections, ensuring proper alignment to prevent exhaust leaks. Verify your system's diameter requirements and desired flow characteristics before installation, as reducer angle and length impact scavenging dynamics in high-RPM applications.
