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

The Schoenfeld Reducer 2-1/2in OD to 3-1/2in ID is a precision exhaust system component engineered to bridge diameter transitions in custom and performance exhaust builds. This 4.625-inch steel reducer connects smaller diameter piping to larger diameter sections, making it essential for exhaust manifold-to-downpipe transitions, turbo applications, or stepped exhaust configurations where diameter mismatches occur.

Constructed from steel in natural finish, the reducer measures 3.65 x 3.65 x 4.75 inches and weighs 0.51 lbs, making it lightweight yet rigid enough for high-temperature exhaust environments. The 2-1/2 inch outer diameter to 3-1/2 inch inner diameter specification creates a smooth transition that minimizes turbulence and flow restrictions. Schoenfeld's manufacturing ensures consistent wall thickness and precise bore dimensions critical for proper sealing and fit in exhaust manifold assemblies.

This reducer is designed for street machines, race vehicles, and custom hot rods requiring stepped exhaust transitions. Mechanics and fabricators choose this component when building custom headers, turbo systems, or modified exhaust routes where stock piping diameters don't align. The natural steel construction accepts welding, painting, or ceramic coating to match specific build aesthetics and thermal requirements.

Exhaust diameter transitions are often overlooked in performance builds, but mismatched transitions create backpressure spikes and restrict scavenging efficiency. This Schoenfeld reducer solves that problem with a tapered profile that maintains velocity through the transition while accommodating the diameter step. Whether upgrading turbo plumbing, installing oversized exhaust systems, or fabricating custom manifold work, this reducer provides the precision fitment required for quality exhaust system integration.
