Those organizations found significant(3-5%) increase in performance when exhaust stacks were well designed. If the difference between life and death is a small difference in climb speed or speed degradation in a maximum performance turn then this truly matters. Nowadays it would be a difference in range and possibly high altitude performance. As a side note you might find Greg's Youtube videos interesting. He just started a series on propellor design from the Wright brothers on.
