I'm late as always. :D This thread was very informative. I really appreciate all the pics and experiences shared on these headers and the issues to make them work. Having said that, a question/idea!
Why not run 2.25" exhaust? I know on a high HP engine that would kill some power but should be a lot easier to snake over the drag link. Plus, for a stock or mild build I would think 2.25" should be more than enough. Also, even though I know it wouldn't be ideal, you could run 2.25" off the headers then up size it to 2.5" after you clear the drag link.
