Standard Duty HTC Coated Full-Length Headers
  • 1955-57 Chevy Bel Air & 150/210 Series 283-400
  • 1-3/4" Tube, 3" Collector

    • Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and MID-LENGTH tube headers for Pontiac models for decades. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your vehicle's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.
