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.
