Description
Transform your 2021+ Audi A4 (B9) with the Armytrix Valvetronic Stainless Steel Exhaust System. This cutting-edge exhaust system enhances performance by increasing horsepower, reducing weight, and improving sound. Engineered for superior sound engineering and a performance boost, this system provides an upgraded exhaust note, especially in the low to mid rev range. It produces a rich, sporty sound while neutralizing undesirable frequencies at critical RPMs.
The system includes a set of sleek True Titanium Blue Tips that not only improve the sound but also add an aesthetic touch to the rear of your vehicle. Armytrix’s Valvetronic technology is a standout feature, integrating a Throttle Pedal Sensor and Engine RPM Signal Auto Functions to adjust exhaust valves for optimal performance. This innovation provides better control over the exhaust sound and performance, giving you a customizable driving experience.
With the Armytrix Valvetronic Exhaust System, the valves automatically open at high speeds, allowing for increased airflow and greater performance (more horsepower and torque) and a louder exhaust note. When driving at lower RPMs, the valves automatically close to preserve backpressure for a smoother driving experience. The Race Mode fully opens the valves, delivering a straight-pipe flow that unleashes a LOUD, RACE-INSPIRED exhaust note.
