Reducer 3-1/2in OD To 3-1/2in ID

The SCHOENFELD Reducer 3-1/2in OD To 3-1/2in ID (part number 3535) is a precision-engineered exhaust pipe reducer designed for custom exhaust system fabrication and modification. This 4.95-inch-long steel reducer bridges diameter transitions in performance exhaust builds, enabling seamless connections between exhaust components of different sizes while maintaining proper flow dynamics and structural integrity.

Constructed from durable steel in a natural finish, this exhaust reducer weighs 0.69 pounds and features a compact footprint (3.6 x 3.6 x 4.95 inches) suitable for tight engine bay installations. The consistent 3.5-inch measurement for both outer and inner diameters indicates this reducer is primarily used in transition applications where internal smoothing or external adaptation is required.

This component serves fabricators, restoration shops, and serious enthusiasts building custom exhaust systems where off-the-shelf solutions don't fit the application. Whether adapting turbo downpipes, connecting header collectors to intermediate piping, or bridging OEM to aftermarket manifolds, a quality reducer eliminates the need for improvised solutions that compromise flow, durability, or appearance.
