Kooks 1-7/8in x 3in Stainless Long Tube Headers

Headers replace the cast exhaust manifolds bolted to the side of the engine with long, smooth tubes. Exhaust leaves each cylinder with less resistance, which frees up power the manifolds were choking off. These use 1-7/8in primary tubes into a 3in collector and are made from 304 stainless steel.

why this one — The 1-7/8in primary is the large-tube option, so it favors power higher in the rev range and suits a truck that already has an intake and a tune rather than a stock one. Be honest with yourself about the cost before you commit: Kooks states these do not connect to the factory exhaust, so a Kooks Y-pipe is a required extra purchase, they are built to order with a 4-6 week lead time, and this is a full-day job on a lift.
