Long tube headers with stepped primary tubes that start at 1-5/8in and open to 1-3/4in before feeding a 3in collector. The stepped, smaller-diameter design is aimed at exhaust speed low in the rev range rather than peak flow at high rpm.
why this one — This is the header set to pick if the truck is mostly a truck. Smaller primaries keep exhaust gas moving faster at the rpm you actually tow and merge at, which is what Kooks means by Torque Series, whereas the 1-7/8in kit trades that away for top-end. The honest catch is that it is headers only, so a Y-pipe is still a separate purchase, and it is still built to order with a 4-6 week wait.
