BBK 1986-1993 Mustang 351W swap Full length headers have been designed specifically for any Mustang enthusiast who wishes to swap out the smaller 302 block for a larger/ taller 351W block based engine. They feature 1-3/4" primaries for maximum performance with 351W or large displacement stroker engines. These full length headers will help give your large displacement Mustang a throaty exhaust note. The ceramic coating adds durability and helps hold in heat to reduce under hood temperatures.
BBK full length Mustang headers are made from 1-3/4" CNC-machined mandrel bent tubing with 3/8" thick die-stamped flanges. The full length primary tube design creates unrestricted and balanced airflow for ultimate horsepower gains. These headers are pressure tested to ensure leak free performance.
