Scott Drake Exhaust Manifold for 1968-1973 Six Cylinder Mustangs Except IMCO.These manifolds are cast from high quality molds for proper fit and appearance. Includes exhaust flange bolts, nuts and washers.
1965-1967 6 cylinder owners wishing to improve performance can run a 1968-1973 exhaust manifold which has a larger port and more free flowing design. This in conjunction with a larger diameter exhaust pipe and muffler, is the same principle as adding dual exhaust to a V8. Better acceleration, more power and improved fuel efficiency.
