Tradition is to cut down a Model T torque tube, but that would be oversized, so: used motorcycle parts.

Besides being far more difficult to find as mandrel-bent pieces and harder to fabricate, flow would be worse due to interference drag at the 90° intersection between the walls. The only reason square-ish runners are used in intakes or exhausts is for transitions dictated by other components (e.g. bolts, pushrods, adjacent runners).

Yes. In general if not specifically. Also note the oversizing of the 'collector'. I didn't see a version that showed a three-way split.
The asymmetrical flaring of the end cuts would probably improve scavenging.

My initial thought with the pipes going straight back is this could be used to accelerate the air flow past the tail of the underbody like a blown diffuser...

Exhaust is corrosive, anything you do like that would need to be all stainless steel.

With converging and diverging nozzles I believe 7 degrees is ideal.
There are companies that sell 7 degree reducers for intake and exhaust piping, they are kind of expensive.
I picked up a 304 stainless steel 3 to 4 inch reducer pipe used in a water pumping system to be part of my diesel suburbans new exhaust. It has about a 12 degree slope. Not perfect but since it was free I cant argue. (had a welding defect and could not be used in the high pressure RO system it was intended for)
