Condition:
We introduced the high efficiency 4-1 as against the STD 4-2-1. The exhaust efficency of the standard exhaust manifold is not perfect. You could see the change of dramatically driving feeling. The complete equal length is good for the exhaust intervention but reduce the turbine performance and increase the exhaust resistance.
