If you already have the twin outlet manifold then the 4 branch only has minimal advantage. Its the rest of the system where the real gains are to be had.
As to what manifold to go for its a case of where in the engine range you want to make the power. Typicaly 4-1 manifolds are best for high RPM and 4-2-1 manifolds are best to low down. |
