U-Bend Mild Steel 1.250 x 2.25in Radius 18 Gauge

The U-Bend Mild Steel 1.250 x 2.25in Radius 18 Gauge from Patriot Exhaust is a mandrel-bent exhaust component engineered for custom exhaust system fabrication and modification. Whether you're building a high-performance intake manifold runner, constructing a full cat-back exhaust system, or routing headers through a tight engine bay, this U-bend delivers the precision geometry required for optimal exhaust flow. Mandrel-bent construction ensures consistent wall thickness throughout the bend radius, eliminating the kinks and restrictions that occur with traditional press bending methods.

Constructed from mild steel with 18-gauge wall thickness, this U-bend features a 1.250-inch inner diameter tubing and a 2.25-inch center-line radius, providing a smooth 180-degree turn ideal for reversing exhaust direction or creating tight-space bends without excessive pressure drop. The 6-inch legs on each side of the bend offer ample material for welding flanges, bungs, or oxygen sensor bosses, making it compatible with both stock and aftermarket exhaust manifold designs. Mild steel composition allows straightforward TIG or MIG welding while maintaining structural integrity under sustained exhaust temperatures, and the material can be ceramic coated or wrapped for thermal management if desired.

Street rod builders, diesel truck fabricators, and performance engine builders rely on mandrel-bent bends like this to minimize backpressure and maintain scavenging efficiency in custom exhaust systems. The 1.250-inch diameter pairs seamlessly with standard automotive tubing diameters and integrates easily into modular exhaust builds on domestic and import platforms. Weighing just 0.91 lbs, this single bend is ideal for spot purchases during fabrication, and its compact dimensions make it convenient to stock for ongoing projects or small-batch custom exhaust production.
