Hooker's Super Competition Dual Exhaust System is made of mandrel-bent 16-gauge 2.5" aluminized steel tubing. Mandrel bending, which maintains a consistent inside diameter compared to press bending that pinches tubing closed, increases volume and promotes maximum efficiency by reducing backpressure for more horsepower!
