Replaces the old end rise (log style) manifolds and risers, part numbers 913682, 913683, 909218, 982680, or 909863, with new and more efficient center-rise manifolds and risers. Includes 3.5″ exhaust hose to mate up to your original Y-pipe.Note
- This kit does not replace the older “Banana” style OMC Ford manifolds.
- These manifolds utilize one bolt per port, instead of two like original OMC manifolds. This is normal and will not cause any problems.
