If you look at the FI headers, they have 3 long individual runners/pipes that merge into into a single collector just before the flange. If you look at the PPE headers, they have 3 shorter runners/pipes that merge before the flange, and then have a single pipe that runs the last 3-4 inches. My guess, just by looking at them, is PPE did this to stay closer to an equal length on the individual runners, but I am not sure.
