Speed Engineering headers are made out of 304 stainless steel and offer great quality, performance, and affordability. The headers are mandrel bent, tig welded, and feature polished stainless steel construction. All Speed Engineering headers have been dyno proven, and they stand behind their products; you will not find a better fitting, quality built, budget header for your vehicle.
"Our headers also have improved features over competitors. We utilize V-Band collector construction, merge spikes, port matched flanges, and improved header to block/chassis clearance"
Note: "For LT Gen 5 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 betrimmed for proper clearance. Our headers are tucked in tight due to narrow older frame clearance. Fits 6, 8, and 10 Speed Auto Transmissions.
