Speed Engineering LS Swap Headers - Mid Length


Speed Engineering headers are made out of 304 stainless steel and offer great quality, performance, and affordability. These headers are mandrel bent, tig welded, and feature natural stainless steel construction, and they have all 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.

Other improved features over competitors include V-Band collector construction, merge spikes, port matched flanges, and improved header to block/chassis clearance.

Features include:
  • Mandrel Bent Tubing
  • Full 1 5/8" Primaries
  • 2 1/2" Collector
  • V-Band Collector Construction
  • Collector Merge Spikes
  • Port Matched Flanges
  • Gains over 18+ rwhp
  • V8 Engines Only
  • 4.8L, 5.3L, 5.7L, 6.0L, 6.2L Engines
  • CNC Machined Flanges
  • Natural 304 Stainless Steel
  • Standard Graphite Manifold Gaskets

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. These headers are tucked in tight to fit into older, narrow frames.

Excellent product

Out of the box these seem like very high quality. They have very thick flanges and the wall thickness of the tubing seems more than adequate. I installed the headers on an LS swapped c1500 and the only figment issues I had were that I had to re-route my hydraulic clutch line and I had to remove the drivers side tin heat shield. Factory straight boot plug wires will interfere with header tubes on 2-3 of the cylinders so wires with angled boots are a necessity. My only complaint about the headers is that I wish the v-bands were stepped to ensure a concentric fit. Not a huge deal but it would make fitting up the rest of the exhaust a little easier.
