S/S 1-3/4in 45 Deg Bend w/ 1-3/4in Radius

The S/S 1-3/4in 45 Deg Bend w/ 1-3/4in Radius from Vibrant Performance is a precision exhaust mandrel bend designed for custom intake and exhaust manifold fabrication. Built for enthusiasts and professional fabricators who demand quality tubing work, this stainless steel component eliminates the kinks and stress fractures that occur when cold-bending tubing by hand. Whether you're building a high-flow intake tract, constructing a custom exhaust manifold, or routing cooling lines in a tight engine bay, this mandrel bend maintains structural integrity and flow efficiency that directly impacts engine performance.

Manufactured from stainless steel, this 45-degree bend features a 1-3/4-inch outer diameter with a 1-3/4-inch bend radius, geometry that promotes smooth air and exhaust gas flow while minimizing turbulence and backpressure. The mandrel bending process ensures consistent wall thickness throughout the bend, preventing collapse or deformation under boost or thermal cycling—critical for forced induction applications. This specific bend angle and radius combination is ideal for routing tubing around engine components while maintaining aerodynamic efficiency that turbo and naturally aspirated builds alike require for measurable horsepower gains.

Professional fabricators, engine builders, and serious street/track enthusiasts rely on Vibrant Performance mandrel bends for custom intake manifold, cold-air intake, and full exhaust system projects across all displacement ranges. The 1-3/4-inch diameter suits mid-range engine platforms and composite intake systems where flow capacity and fitment balance are essential. At just 1.19 lbs, this component integrates seamlessly into weight-conscious builds without compromise. Installation involves TIG welding to flanges or existing tubing—standard practice for any serious fabrication shop looking to maximize power delivery and reliability.
