U-Bend Mild Steel 1.500 x 6in Radius 18 Gauge

The HOOKER U-Bend Mild Steel 1.500 x 6in Radius 18 Gauge exhaust bend is a mandrel-formed exhaust component engineered for smooth, efficient flow in high-performance and marine exhaust systems. The precise 6-inch radius curve and 1.5-inch diameter tubing are optimized to minimize turbulence and pressure loss compared to crush-bent alternatives, delivering consistent backpressure management across a wide RPM range. This mild steel construction accepts welding, ceramic coating, and polishing, making it adaptable to both stock restorations and custom performance builds.

Built to OEM specifications, the U-bend features 12-inch legs and 18-gauge wall thickness—a balanced profile that resists collapse under load while remaining lightweight enough for fuel-efficiency-conscious applications. The mandrel-bending process (as opposed to standard bending) maintains consistent wall thickness through the radius and preserves internal diameter uniformity, critical for systems where scavenging efficiency directly affects horsepower output. Marine engines, automotive restorations, and performance exhaust fabricators rely on this standard because it eliminates the flow restrictions and turbulence caused by pinched or wrinkled bends.

This component serves fabricators, engine builders, and DIY enthusiasts who prioritize precision over off-the-shelf shortcuts. Whether integrating into a marine engine cooling system, a fuel-injected street engine, or a vintage hot rod project, the mild steel material allows full customization—tig or mig welding, mandrel bending for secondary curves, thermal coating, or polishing to match existing piping. The 3.55-pound weight and compact shipping dimensions (14.8 x 2.8 x 20.8 inches) make it practical for fabrication shops and individual builders to stock or integrate into modular exhaust kits.
