I am not sure on that one. I have heard people calling it "JDM pie cut". Its not true JDM its more of a technique of making tubing bend without using a mandrel.

You take a straight section of pipe, and cut multiple wedges or "pie cuts" out of it, and then weld it back together. It's popular as you can make custom bends on the cheap.

There are, however, a couple American companies that do something close to what you are talking about...

the reason people did this is not for performance, as it is NOT as good as a smooth bent tube
however, the reason it can be beneficial is that you can make a tighter bend and it can be more complex...if you tried to bend a tube to some of the tight angles pie cuts can accomplish the tubing would "kink" (for lack of a better word)
also, one of the pics above shows titanium tubing, which is not a metal that bends easily due to how brittle it can be...so in that instance it would almost be necessary
