1 7/8" x 2" x 3" Signature Series Stepped Stainless Steel Longtube Headers. Includes Extra O2 Bung for a Wide Band O2 Sensor Comes with O2 Extension Kit (2-18"and 2-6").
A stepped header creates a more usable torque and power curve for street use. They are more suitable for applications where there are large rpm changes such as a gear shift in a manual transmission or sweeps through the rpm range on the track. It accomplishes this by taking advantage of 2 sets of pulse waves created by the 2 lengths of a single primary. The top step creates the first length which it tuned to a higher rpm. The total length of the tube, top and bottom steps, creates the second wave which is tuned to a lower rpm. Essentially a stepped header creates more area under the curve (dyno graph) and offers up more usable power than a single diameter primary header.
