There is a rapid section change from the outlet diameter of the 997 diverter tee to the 3.2 inlet plenum diameter. Inside there is an exposed plenum entrance edge created by stretching the stock boots to fit the 997 diverter tee larger diameter. In 3d one could visualize this as a v-section ring disrupting airflow over it. Section changes and edges generally result in flow losses in closed piping.
This is why I am hoping that Ben has matched diameters....Ben can you verify explicitly?
Of course these assumptions have to be verified with flow testing. Torque power and throttle response being the goals.
