90 Degree Mandrel Bend 1.75in O.D. 16 Gauge SS

The 90 Degree Mandrel Bend 1.75in O.D. 16 Gauge Stainless Steel from Vibrant Performance is a precision exhaust or intake piping component designed for custom automotive fabrication and high-performance engine modifications. Built for builders and mechanics who demand consistent flow characteristics and durability, this mandrel bend eliminates the kinks and flow restrictions that occur with traditional crush bends. Whether you're designing a custom exhaust system, turbo intake manifold, or intercooler piping, this 90-degree turn maintains structural integrity while preserving critical airflow dynamics that directly impact engine performance and throttle response.

Mandrel bending is the gold standard in custom tube work because the internal mandrel support prevents wall collapse and thinning during the bending process. This 1.75-inch outer diameter stainless steel bend maintains optimal tube wall thickness throughout the 90-degree radius, ensuring superior pressure handling and extended component lifespan compared to non-mandrel alternatives. The 16 gauge stainless construction resists corrosion from exhaust heat cycles and moisture exposure, while the smooth internal radius minimizes turbulence and maximizes volumetric efficiency—critical factors in forced induction systems, naturally aspirated builds, and cooling system upgrades where flow path optimization directly translates to measurable horsepower gains.

This mandrel bend serves professional fabricators, engine builders, and serious DIY enthusiasts undertaking custom exhaust or intake manifold projects on domestic and import platforms alike. The 1.75-inch O.D. sizing is commonly specified for mid-range displacement engines (typically 2.0L to 5.0L) where balance between flow capacity and packaging constraints is essential. Installation requires welding skills and proper jig setup to maintain system alignment, making it ideal for shops with TIG welding capability. Weighing 1.47 lbs and dimensioned at 6.65 x 2.3 x 13.65 inches, this component is ready to integrate into your custom fabrication workflow immediately upon arrival.
