Vortex/Swirl Exhaust Manifolds and system

Votex/swirl exhaust manifold would work by manufacturing helical shapes from the header to the cats and further to the mufflers creating a flow and possible a significant performance increase. Various sizes of these veins could produce a multitude of silencing and resonance features. Currently many of the manifolds work to extract the air well but if it is possible to draw it out faster with a smoother discharge the fuel saving, emission and turbo applications may be greatly impacted for the better.
