Description
The Armytrix Replacement Valvetronic Muffler for the Audi A5 Quattro and A5 Sportback 2.0 TFSI B9 is engineered to deliver an aggressive performance upgrade while maintaining everyday drivability. Designed as a direct replacement muffler, this system enhances horsepower and torque, reduces overall exhaust weight, and significantly improves exhaust tone.
Precision-built from high-quality stainless steel, the Armytrix Valvetronic muffler delivers noticeable gains in the low and mid RPM range while producing a deep, sporty exhaust note. At the same time, it effectively neutralizes unwanted drone and harsh frequencies in critical cruising RPM zones, ensuring a refined driving experience when needed.
What truly sets this system apart is Armytrix’s advanced Throttle Pedal Sensor and Engine RPM Signal Auto Function. This intelligent valve control technology automatically closes the exhaust valves at low RPM to preserve backpressure for smoother launches and daily driving. At higher RPM and increased throttle input, the valves open to maximize airflow, unlocking enhanced performance and a more aggressive exhaust sound.
Drivers can customize valve behavior based on engine RPM and throttle position, allowing seamless transitions between comfort and race modes. When race mode is activated and the valves are fully open, exhaust gases flow through straight piping for maximum sound and performance. Under full throttle, the system delivers an unmistakable race-inspired exhaust note for an exhilarating driving experience.
