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.

Prototype shown here has been tested by "Wild Diesel" on their 1st place winning 2000 hp puller.  using sensors on every cylinder EGTs dropped by 8% over the ATS manifold they were using previously.  

This header will come high temperature coated.

Lead time is currently 4-5 weeks.
