Kooks 1-3/4" x 3" 304 stainless steel weld-up custom header kit — the full set of pre-cut pieces a fabricator needs to build custom long tube headers for any application. The right starting point for one-off swaps, custom chassis builds, or applications Kooks doesn't make a stocked header for.
Universal application. Customer supplies head flanges, gaskets, bolts, and fabrication labor. Confirm fabrication capabilities before ordering — this is a raw materials kit, not a bolt-on product.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every J-bend and merge collector in this kit is sourced and inspected in the same shop where the company's racing legacy was built. 304 stainless construction handles thermal cycling and corrosion.
Includes 12 x JB-175-25-18-304 (1-3/4" J-bends) and 2 x 9903S (1-3/4" x 3" merge collectors).
