Steed Speed Competition Style T4 12V

Competition manifold with straight T4 flange

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.

Shown here is T4 version.

This version replaces our original design to improve strength and lower the cost.

Manifold is available as T4 or T6 version.
