Premium Stainless Steel Headers for GM Trucks & SUVs

Elevate the performance and durability of your classic GM truck or full-size SUV with these premium Hedman Hedders stainless steel headers. Engineered for Small Block Chevy (SBC) engines, these headers are designed to optimize exhaust flow, delivering significant improvements in horsepower and torque. The 1.625-inch primary tubes are perfectly sized to maximize scavenging efficiency for most street-driven SBC applications, while the robust 3-inch collector ensures maximum exhaust gas evacuation.

Superior Construction & Fitment:

  • Engine Fitment: Designed for Small Block Chevy (SBC) engines
  • Vehicle Fitment: Fits GM Fullsize SUVs and Trucks from 1967-1991
  • Primary Tube Size: 1.625 inches for excellent street performance and torque
  • Collector Size: 3 inches for high-flow exhaust exit
  • Material: High-quality stainless steel for exceptional corrosion resistance and longevity
  • Finish: Natural stainless finish for a clean, premium look
  • Included: Gaskets and hardware are included for a complete installation

Crafted from high-grade stainless steel, these Hedman Hedders offer superior resistance to rust and corrosion, ensuring they will withstand harsh environmental conditions and maintain their performance for years to come. By replacing restrictive stock exhaust manifolds, these headers allow your SBC engine to breathe more freely, resulting in a more aggressive exhaust note and a noticeable boost in power. The natural stainless finish provides a sleek, high-performance appearance under the hood. Invest in top-tier exhaust components for your classic GM vehicle.
