Anyone know anything about what design elements (pipe diameter, length, bends, etc) make for best torque/horsepower, and optimizing powerband and stuff like that? Like for someone who was going to fabricate their own?

A lot of it has to do with your own car, port types and the like. R&D is everything.

There is some good info here, just ignore the flywheel junk.
