Make headers for the space your project gives you
Kooks WK2250 gives your fabricator the 304 stainless bends and collectors for a custom 1-3/4-inch-primary header. Shape the tubes around the installed engine and chassis, then connect the 3-1/2-inch collector outlets to the exhaust you choose.
SKU: WK2250
The tube components are supplied
Twelve JB-175-25-18-304 J-bends and two 9904S collectors are included. The primary tube size and collector outlet size are clearly defined for planning the fabricated assembly.
Add flanges that match your heads
Two header flanges are required separately. Choose the actual cylinder-head port and bolt pattern, with final tube routing and clearance established before welding.
Ordering and delivery
Estimated lead time is 4-6 weeks. Delivery may be faster depending on stock levels. Shipping is charged separately.
