Design & Engineering

The Armytrix AU942F-QS11B exhaust system is a testament to precision engineering. Each component is crafted from premium stainless steel, ensuring longevity while providing the necessary rigidity to withstand extreme conditions. The system incorporates a unique Throttle Pedal Sensor and Engine RPM Signal Auto Functions, enabling a seamless transition between quiet operation and a robust, race-inspired sound profile.

At low RPMs, the exhaust valves automatically close, maintaining backpressure for optimal launch characteristics. As you push the throttle deeper, the system's intelligent design allows for the valves to open at high RPMs, facilitating an unobstructed flow of exhaust gases. This results in a palpable increase in horsepower and torque, particularly in the low to mid-rev range, where performance is most critical.
