S/S U-J Bend 1-1/2in W/ 3in Radius 16 Gauge

The S/S U-J Bend 1-1/2in W/ 3in Radius 16 Gauge from Vibrant Performance is a stainless steel exhaust tubing component designed for custom fabrication and high-performance exhaust system builds. This mandrel-bent U-bend tube serves as a critical transitional element in custom exhaust routing, allowing builders to change flow direction without creating turbulence-inducing kinks or crimps. Whether you're constructing a full custom exhaust system, repositioning piping around engine bay obstacles, or designing a turbo manifold downpipe, this precision-formed bend eliminates the need for welding multiple straight sections at angles.

Constructed from 304 stainless steel and mandrel-bent to a smooth 3-inch radius, this tube maintains consistent 1-1/2-inch diameter throughout the bend, preserving scavenging efficiency and minimizing exhaust gas velocity losses. The 16-gauge wall thickness provides durability against thermal stress and vibration while remaining light enough for performance applications. Mandrel bending technology ensures the tube's interior wall remains smooth and uniform—critical for exhaust flow optimization and preventing turbulent eddies that reduce horsepower and increase backpressure.

This component benefits builders, fabricators, and performance mechanics working on turbocharged, supercharged, and naturally aspirated engine builds where custom exhaust routing maximizes scavenging and minimizes restriction. The 1-1/2-inch diameter accommodates small-block to mid-size engine applications across domestic and import platforms. Installation requires welding or slip-fit coupling to adjacent tubing sections; precise measurement and fitment verification are essential before final installation. Stainless steel construction ensures corrosion resistance, making this bend suitable for both street and track use in wet environments.
