    The Headers actually weight 44 pounds, but billing weight is 53 pounds, and dimensional weight goes to 81 pounds because the box is so big.

    These are show quality chrome stepped headers with collectors. These headers feature CNC laser machined flanges and two-stepped 28″ equal length tube design. Unlike other brands, unique double wall port gussets support the tube and eliminate cracking at the flange. Headers include 4-1/2” outlet slip on racing collectors with U-tab mountings for bolt-on installation. The complete header package is finished in show quality chrome. You can pay more but you can’t get better! These Headers are a COMPLETE SET and fully chromed with 4-1/2 inch Merged Collectors, header gaskets, and header bolts, and hardware to put on the collector.
