How It Works

This base design is aluminum, with a temperature controlled press fit between the divergent cone and the regulator, resulting in a permanent seal.  The exhaust cover fits between the divergent cone and the aluminum-threaded cap.  It can be locked down in any position, and will not leak, due to the seal on both ends.

In the idle position, the piston is held in by spring tension with the regulator port partially closed, causing the bulk of the gases to escape through the by-pass port.
 

 

As the engine speed increases, the piston moves towards the rear of the exhaust, compressing the spring and opening the regulator slot, allowing the maximum amount of gases to escape the system at mid-engine operation.
 

The engine speed continues to increase from the mid-range, while the piston continues to move towards the rear of the exhaust system. At this point, the piston closes off the regulator port, gradually restricting the gases to the point that no gases will escape through the regulator port, leaving only the by-pass port for gases to escape.   The by-pass port is calibrated for top speed based on engine size, and is typically a smaller hole than a stock exhaust system.

The Vortice-BR is non-adjustable, and all that needs to be done is to simply install the silicone coupler, fuel vent line, and the end support, then you're ready to go.  The Vortice has been designed to be leak-free and simple to install.
