This construction method has allowed our engineers the design freedom to be able to transition the inlet from the throttle body with a smooth, free flowing radiused bend into the manifold plenum. Reducing turbulence and therefore increasing efficiency.     REDUCED BACKPRESSURE Reducing backpressure (resistance) increases efficiency.  By removing the choke point of the manifolds backpressure is reduced. The Choke point is like a gate, closing the gate part way restricts how much can get through the gate at one time, no matter what is trying to get through the gate, and how hard the push is, the gate restricts the flow. The backpressure created inside the factory manifolds not only red
