Speed Engineering LT Swap Headers - 1-7/8" Full Length


Speed Engineering headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Their headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of their headers have been dyno proven. Speed Engineering stands behind their headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

  • Mandrel Bent Tubing
  • 1 7/8" Primaries
  • 3" Collector
  • Merge Spikes
  • V8 Engines Only

Note: "Due to older vehicle frame clearance headers are pulled in very tight, and require our LT spark plug wires".

Note: "For LT Direct Injected series engine swaps only" These do not work on standard SBC or BBC engines.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance.
