STEED SPEED | Cummins 5.9L 12 Valve Competition Style T6 Flange Manifold

STEED SPEED Competition manifold for Cummins 5.9L 12V with straight T6 flange on 10 degree angle

This header has been designed for those who are pushing the extreme limits with their Cummins.  Passages are bigger than the standard manifolds with revised passage route to give more flow potential and lower EGTs.  This version replaces our original design to improve strength and lower the cost.
