Reducer 3in OD To 3in ID

The Schoenfeld Reducer 3in OD To 3in ID is a precision exhaust system transition coupling designed for custom and high-performance automotive builds. This reducer is essential for mechanics and fabricators looking to step down primary tube diameters or manage header-to-collector transitions in both competition and street applications.

Featuring a consistent 3-inch diameter throughout, this reducer ensures a smooth transition that maintains flow efficiency and structural integrity. Its compact design, with a length of 4.95 inches, allows for installation in tight engine bay configurations without compromising exhaust flow characteristics. The lightweight construction, weighing just 0.58 lbs, contributes to reduced overall system weight while ensuring durability for high-RPM operation.

This reducer is ideal for fabricators and engine builders constructing custom exhaust systems, particularly when consolidating multiple primary tubes into a single collector or adapting legacy headers to modern piping standards. Its mandrel-bent design minimizes turbulence, preserving scavenging efficiency and exhaust velocity through the merge zone, making it a valuable component for any serious exhaust system.
