720575 Mild Steel 6 Radius U Bends with Two 12 Long Legs 1 3 4 45MM

These Hooker Headers mandrel bends are the foundation for building a bespoke Harley-Davidson exhaust system. Fabricated from 16-gauge mild steel, these 180-degree J and U-bends are shaped using modern mandrel bending machinery to ensure a smooth, wrinkle-free internal diameter without crimping. This process maintains consistent exhaust gas velocity and flow, which is critical for performance tuning. Whether you are fabricating a set of custom drag pipes or a complex two-into-one system, these raw steel components provide the versatility needed for unique frame clearances and aesthetic choices. Hooker’s reputation for exhaust engineering ensures these bends meet professional fabrication standards.
