• With the valves closed, exhaust gasses travel through a sound reduction path via a smaller 2.5 (63.5mm) pipe, reducing volume and allowing the system to act more civilized when needed.
• The entire system is increased to a dual 3 (72mm) exhaust path.
• With the exhaust valves open, the exhaust gasses travel uninterrupted from the front of the system out through the exhaust tips.
• When exhaust gasses travel into the multichambered rear muffler / resonator, they continue uninterrupted and a Helmholtz resonator reduces drone frequences without restricting flow on the open-valve path.
