U-Bend Mild Steel 2.500 x 4in Radius 16 Gauge

The U-Bend Mild Steel 2.500 x 4in Radius 16 Gauge from PATRIOT EXHAUST is an essential fabrication component for custom exhaust system builders and performance automotive shops. This precision-bent tube forms the foundation of smooth, efficient exhaust flow routing, allowing you to navigate tight engine bays and create professional-grade exhaust manifolds, downpipes, and mid-pipe assemblies. Whether you're building a street machine, race car, or restoration project, this U-bend eliminates the need for welded elbows and multiple segments, reducing potential leak points and improving structural integrity in your exhaust pathway.

Manufactured from cold-rolled mild steel, this U-bend features a 2.5-inch outer diameter tubing with a 4-inch centerline radius and 16-gauge wall thickness, providing excellent strength-to-weight balance for high-temperature exhaust applications. The 4-inch radius bend is engineered to minimize turbulence and backpressure while maintaining structural rigidity under thermal cycling and vibration stress. Mild steel's superior workability allows for TIG or MIG welding to adjacent pipe sections without brittleness, and its thermal properties make it ideal for direct contact with hot exhaust gases without the premium cost of stainless steel—perfect for budget-conscious builders who demand performance.

This component is ideal for custom fabricators, speed shops, and experienced mechanics tackling V8 swaps, turbo installations, or exhaust system redesigns on classic cars and modern performance platforms. The 10.5 x 2.5 x 11.4-inch packaged dimensions make it easy to ship and store on your shop shelf. Installation requires proper welding equipment and pipe-fitting knowledge; ensure all welds are stress-relieved and inspected for quality before pressurizing or running high-RPM engine builds. Pair this U-bend with high-temperature ceramic coating or mandrel bends for optimal flow characteristics in your complete exhaust system.
