We stand behind our headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

  • Mandrel Bent Tubing
  • Full 1 3/4" Primaries
  • 3" Collector
  • Collector Merge Spikes
  • Port Matched Flanges

Note: "For LS series engine swaps only" These do not work on standard SBC or BBC.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance. Our headers are tucked in tight due to narrow older frame clearance.
