Show original supplier description
Upgrade your Audi A5 Sportback with the ARMYTRIX Valvetronic Stainless Steel Exhaust System. The Valvetronic system offers precise control over your exhaust note. Featuring "Throttle Pedal Sensor and Engine RPM Signal Auto Functions," it intelligently manages exhaust valves based on throttle input and engine RPM. This ensures optimal performance, closing valves at low RPM for better launch-start without backpressure loss and opening them at high speeds for increased airflow, power, and sound. Owners can customize valve timing via a wireless remote or smartphone app. This exhaust system is meticulously crafted from stainless steel and includes quad chrome polished silver tailpipes for a distinctive look. The system comprises a front pipe, mid pipe, Y-pipe, Valvetronic mufflers, and wireless remote control kits. Fitment is specific to the Audi A5 Quattro 2.0 TFSI B9 (2016-2022) and Audi A5 Sportback 2.0 TFSI B9 (2016-2021). A crucial note for installation: the muffler with quad-tips is only compatible with an S4 Style Quad diffuser on a non-S-line rear bumper, or with an S4 rear diffuser on an S-line rear bumper. The ARMYTRIX wireless valvetronic wiring utilizes a plug-and-play system, ensuring no cutting or alteration to factory settings.
