You say that there are no measurable gains from "taking a few bends out of the exhaust", yet you claim that there are measurable gains from "mandrel-bent curves" in the exhaust.
So, given the OP's question, you're essentially telling him that more power can be had using a mandrel-bent, curvy exhaust, than a straight, bend-free, less restrictive exhaust, correct?

^_^ Its fun to wait and see who corrects something when I sit on my hands(thread).
So Christ I was kinda waiting on you to show up here, I'm not aware of a block that has the exhaust exiting the block in a straight line from valve to tip so I don't have any way to speculate on the difference.
I would assume its pretty significant considering manufacturers always use smooth curves and make it travel in as much of a straight line as possible. Also too many curves are the problem with turbos and high performance race kits try and get the air to the turbine with as few twists and turns as possible.
