The Schoenfeld Reducer 2-1/2in OD to 3-1/2in ID (model 2535) is a precision exhaust transition component designed for custom exhaust system fabrication and engine bay modifications. This reducer bridges a critical diameter gap between smaller-diameter primary pipes and larger collector or muffler inlet tubes, making it essential for builders constructing high-performance exhaust systems on street rods, race cars, and modified street engines.

Manufactured by Schoenfeld—a trusted name in performance exhaust design—this reducer features a tapered, seamless transition that minimizes turbulence and backpressure at the diameter change. The 2-1/2-inch outer diameter (OD) inlet accepts standard aftermarket exhaust piping, while the 3-1/2-inch inner diameter (ID) outlet integrates with larger-bore collectors, muffler inlets, or custom tubing.

This reducer is ideal for engine builders, providing a solution that eliminates costly custom welding and ensures a smooth, efficient gas flow path. The lightweight construction (0.51 lbs) makes installation straightforward in tight engine bays, and the precision-formed shape ensures leak-free welds and a professional appearance.
