90 Degree Reducer Elbow 1.75in I.D. x 1.5in I.D.

The 90 Degree Reducer Elbow 1.75in I.D. x 1.5in I.D. by Vibrant Performance is a precision intake and exhaust transition fitting designed for custom automotive tuning and engine modification work. This reducer elbow serves a critical role in high-performance setups where ducting, intercooler piping, or exhaust systems need to change direction while simultaneously stepping down in diameter. Whether you're building a turbo intake manifold, relocating cooling lines, or fabricating custom exhaust headers, this fitting provides the smooth transition necessary to maintain flow efficiency and minimize turbulence.

Manufactured by Vibrant Performance—a trusted name in performance ducting and fluid conveyance systems—this 90-degree elbow features a 1.75-inch inlet diameter that reduces to 1.5-inch outlet diameter, allowing seamless integration between different pipe sizes in your system. The precision angle ensures optimal flow characteristics without sharp bends that would create turbulent vortices and pressure loss. Vibrant's quality construction means this fitting can handle both intake charge cooling and exhaust gas applications, maintaining structural integrity under sustained thermal and pressure cycles common in modified engines. The compact footprint (9.06 x 2.09 x 12.01 inches) fits tight engine bay layouts without excessive bulk, while the lightweight design at 0.58 lbs contributes minimally to vehicle mass.

Mechanics and fabricators routinely specify this reducer elbow for turbo and supercharger installations, custom intake manifold work, and exhaust system modifications on street and race vehicles. It pairs easily with standard 1.75-inch and 1.5-inch diameter tubing, making installation straightforward for anyone with basic hose clamp assembly experience. The MPN 19786 ensures compatibility verification across multiple platforms—from domestic muscle cars to import tuning projects—where stepped-diameter transitions are required to optimize airflow while meeting clearance constraints.
