While not a direct answer to your question, I will say that one of the problems with the platform has been finding a balance on what is ideal and what is sufficient. Some people will say, "No, that method is trash" even though a log style manifold has been making power since the beginning of time. It may not have every freakin optimization taken into account with the design, but its plenty good in many cases, and when you're involved in product development, you often have to make some sacrifices or changes to keep the formula in check. Going with a log style manifold is completely acceptable and it reduces the price in a way that doesn't mean you've taken risky shortcuts. This is not a civic, but this isn't a lambo either, bring on the cast log manifolds IMO.
