Hooker Headers Competition Dual Exhaust Kits are designed to fit specific applications using Hooker Competition Headers or stock exhaust manifolds. They have 2.25" diameter 16-gauge aluminized steel tubing that's mandrel bent to maintain a consistent inside diameter for maximum flow (press bending crushes the pipe, which can reduce volume by more than 10%).
