Kooks Stainless Steel Stepped Long Tube Headers create a more useable torque and power curve for street use. They are 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. The design accomplishes this by taking advantage of two sets of pulse waves created by the two lengths of a single primary. The top step creates the first length which is 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 useable power than a single-diameter primary header.
