U-Bend Mild Steel 2.250 x 6in Radius 16 Gauge

The U-Bend Mild Steel 2.250 x 6in Radius 16 Gauge from Patriot Exhaust is a critical component for custom exhaust system fabrication and engine modification work. Whether you're building a high-performance exhaust manifold, turbo downpipe, or intake ducting system, this mandrel-bent tube provides the precise geometry needed for smooth flow dynamics and professional-grade construction. Mechanics and fabricators rely on pre-bent sections like this to reduce labor time and eliminate the structural weak points that occur with hand-bending mild steel tubing.

The 2.250-inch outer diameter and 6-inch radius bend are optimized for mid-range engine applications where flow efficiency directly impacts throttle response and power delivery. The 16-gauge wall thickness (approximately 0.0598 inches) balances structural rigidity with weight savings—thick enough to withstand vibration and thermal cycling during long-term engine operation, yet light enough to reduce unsprung mass. Mild steel construction accepts welding readily, takes a ceramic coat for heat rejection, and can be TIG or MIG welded without brittleness issues common to harder alloys. The smooth mandrel bend eliminates any interior ridging or collapse that disrupts exhaust gas flow and creates unwanted backpressure.

Custom exhaust builders, engine tuners, and fabricators working on street vehicles, track cars, and engine swaps choose this component for its consistency and precision fit. The 6-inch radius works well in tight engine bay layouts typical of LS swaps, small-block Chevy modifications, and Ford EcoBoost turbo applications. Installation requires basic welding skills and proper alignment to adjacent tubing sections; the mild steel material allows straightforward modifications if final fitment adjustments are needed. Stock this bend for rapid project turnaround and professional results in any high-flow exhaust system.
