1-7/8in O.D. 45 Degree M andrel Bend

The Vibrant Performance 1-7/8in O.D. 45 Degree Mandrel Bend (part number 13095) is a precision exhaust component engineered for custom exhaust system fabrication and modification. This mandrel bend delivers smooth, consistent radius bending without kinking or collapsing the tubing, preserving internal flow characteristics essential for optimal exhaust scavenging and engine performance.

Constructed from 16-gauge stainless steel, this exhaust bend features a 2-inch radius and 6 x 6 inch legs, providing the geometry needed for tight routing in engine bays where standard bends would interfere with adjacent components. The mandrel construction—where a shaped form is used during bending—prevents the collapse that occurs with free bending, maintaining the full 1.875-inch outer diameter throughout the curve. Stainless steel construction resists oxidation and thermal degradation, critical in high-temperature exhaust environments where mild steel would corrode within months.

This component is suited for builders and fabricators constructing or modifying exhaust systems on performance vehicles, hot rods, and custom builds where stock exhaust routing is incompatible with engine modifications. The 45-degree angle and compact 2-inch radius accommodate space-constrained applications while maintaining smooth flow transitions. Mandrel-bent tubing is preferred over crush-bent alternatives because it eliminates internal wrinkles and diameter reduction that restrict exhaust gas velocity and increase backpressure.

Vibrant Performance is recognized in the automotive exhaust and intake systems market for mandrel-bent tube quality and precise radius tolerances. This 1-7/8in mandrel bend integrates seamlessly with standard automotive tubing and flanges, making it a reliable choice for both professional fabrication shops and dedicated enthusiasts building custom exhaust systems.
