Make the headers fit your project
A custom engine installation needs pipework that follows the space you have. Kooks WK2850 gives your fabricator twelve 2-1/8-inch J-bends and two 3-1/2-inch-outlet collectors in 304 stainless steel, ready to cut, position and weld for your build.
SKU: WK2850
The bends and collectors are supplied
The kit includes twelve JB-213-30-18-304 bends and two 9910S collectors. The 2-1/8-inch tube size and 3-1/2-inch collector outlet are separate dimensions, giving you the sizes needed to plan the header and connecting exhaust.
Choose the flanges for your cylinder heads
Two header flanges are required and purchased separately. Select the exact head port and bolt pattern, then have the fabricator arrange the primary tubes around your steering, suspension and engine position.
Ordering and delivery
Estimated lead time is 4-6 weeks. Delivery may be faster depending on stock levels. Shipping is charged separately.
