I was a bit conflicted whether to point out your consideration at that point. The UP is top on the list for the 2.0 but well down it for the 2.5. I see it more in the range of "A variety of other things can be done still though to improve flow". I may insert a comment in point #1 as listing it again later would be awkward. It should be pretty well spelled out in the exhaust FAQ as well though.
