Based on backpressure and pulse waves for exhaust gases, Is there any known advantage of the pair of 2-into-1 downpipes used on the 1st gen M3 headers vs. the 4-into-1 collectors on the 320i's, 318i's, etc?

If so, and being that the 1st gen M3 uses the M10 engine block, should I use one on my '84-'85 318i buildup?
