Re: New Crate Motor-Manifolds vs Headers

Unless your constantly over 5,000 rpm headers have nothing on rams horn manifolds . You don't have to notch your cross member to run 2 1/2" straight drop rams , no issues with leaks or spark plug access .

This is the 4" bend on 2 1/2" pipe to clear cross member any good muffler shop should be able to fit them without issues .

Grumpy
Hope you are doing well buddy. Question for you in regards to the above. I am trying to decide on headers or the ram horn straight drop manifolds you mention... BUT I have a newly built 383 Stroker putting out about 420 HP. Would you still recommend the ram horn manifolds over headers? If so I am thinking of ordering ceramic coated ones ... Thanks man.
