The Vortex Expansion Chamber is an efficient flow-through design with a twist-literally. As the turbulent exhaust enters the chamber's larger diameter, it's contoured and spun by a special set of vanes. The result is a drop in pressure, which aids in scavenging the system. Flow velocity is kept high and unwanted backpressure is reduced.

The Venturi Extraction Tip assists the incoming flow from the Vortex Expansion Chamber. The innovative design utilizes the fast moving air going under the vehicle. The resulting venturi effect creates a low pressure area in the tip, which helps to extract the gasses. The effect increases with speed.
