90 Degree Brushed Mandre l Bend 4.00in O.D; Leng

The 90 Degree Brushed Mandrel Bend 4.00in O.D. from Vibrant Performance is a precision exhaust component engineered for builders and enthusiasts who demand leak-free, high-flow exhaust systems. This mandrel-bent elbow serves as a critical junction point in custom exhaust fabrication, redirecting exhaust gas flow while maintaining structural integrity under thermal and pressure cycling. Whether you're assembling a performance exhaust for street, track, or show applications, this bend eliminates the flow restrictions and stress concentrations that welded or crimped alternatives introduce.

Crafted from premium stainless steel with a brushed natural finish, the 90 Degree Brushed Mandrel Bend features a 4-inch outer diameter and a 4-inch radius, with 5.91-inch legs that accommodate standard tubing dimensions and spacing requirements. The mandrel-bending process ensures the tube wall maintains consistent thickness throughout the bend, preventing collapse and preserving flow efficiency—a key advantage over cheaper crush-bend alternatives. Stainless construction resists rust, corrosion, and thermal degradation, making this bend suitable for both mild street applications and high-heat performance environments.

This component is ideal for exhaust technicians, custom fabricators, and performance builders integrating 4-inch diameter piping systems. The consistent 4-inch radius and dual 5.91-inch legs ensure compatibility with standard flanges, collectors, and muffler inlets, reducing fitment surprises during assembly. Installation requires standard TIG welding equipment and basic metalworking skills; proper joint preparation and heat management extend component longevity and system reliability. Weighing 2.43 lbs, it ships ready to weld into your custom exhaust project.
