Unlike any other exhaust, this system allows the driver complete control over the exhaust performance and sound attributes. Strategic placement of butterfly valves in the system allows for instantaneous control between Normal and F1 modes. A switch placed within the cabin controls the valves. With a simple flip of the switch, the driver selects between Normal and F1 modes.

Normal Mode: This path is a traditional path that takes the exhaust through the catalytic converters and muffler chamber before it exits at the rear tips.

F1 Mode: This path bypasses both the catalytic converters and muffler chamber, thus taking the exhaust straight from the manifold to its exit at the rear tips. F1 Mode produces the greatest possible horsepower gain with a true F1 race-style sound.
