Hooker Headers – Exhaust Header
Description
Hooker Competition headers (SKU 3901HKR) offer the best value in the high-performance header market. Made of durable 16-gauge mild steel tubing, the design uses a long transition collector to reduce back pressure and increase exhaust flow. The 5/16 in. machined flanges with welded O-ring seals ensure a perfect sealing surface. Mandrel-bent tubing maintains metal strength and provides consistent tube diameter at radii to maximize performance. Heat-cured, high-heat-resistant black paint finish. Compatible with Pontiac Firebird 5.7L and 6.6L engines. All installation hardware included.
