Product Description

The Vibrant Performance 2613 4" U-J Mandrel Bent Tubing is a premium universal fabrication component designed for custom exhaust, turbo, intercooler, and other piping applications requiring large-bore stainless steel tubing. Crafted from T304 stainless steel, this U-J-style bend section incorporates both a 180° and a 45° angle in one part, along with a usable straight section - giving fabricators up to three routing options from a single piece. The mandrel bend ensures that the internal diameter stays consistent through the turns, promoting excellent flow characteristics and minimizing restriction common with crushed bends.

Perfect for performance exhaust systems, intercooler piping paths, and turbo plumbing where larger diameter tubing is required, the 2613 tube is ideal for custom builds on cars, trucks, and motorsport applications. Because it is a universal fabrication part, fitment depends on matching the 4" diameter to your application requirements. Its durable stainless construction stands up to high heat and corrosion, and minimal prep work is needed before welding into your project. Whether you're creating a custom downpipe, exhaust, or charge-air path, this tubing simplifies complex routing while maintaining strength and flow.
