{"product_id":"valvetronic-exhaust-system-4","title":"Valvetronic Exhaust System","description":"The ARMYTRIX Valvetronic Exhaust System is engineered to transform your Audi A4 or A4 Avant B9 (2016+) with a 2.0 TFSI 2WD Non-OPF engine.\n\nAt the core of this exhaust system is the innovative Valvetronic technology. This allows for on-the-fly control over exhaust sound and performance. Utilizing unique Throttle Pedal Sensor and Engine RPM Signal Auto Functions, the valves intelligently adjust based on your driving style. When at low RPM, the valves close to maintain essential backpressure for optimal launch starts. As you accelerate, the valves open to allow for greater airflow, resulting in increased horsepower and torque. The system also provides the flexibility to fine-tune valve timings for precise control over sound and airflow according to RPM and throttle input.\n\nEngaging race mode fully opens the exhaust valves, creating a straight-pipe flow that maximizes power output and produces an exhilarating, race-inspired sound. The system includes a front pipe (AU942-F), mid-pipe (AU942-M1), Y-pipe (AU942-M2), Valvetronic mufflers (AU942-VML + AU942-VMR), a wireless remote control kit (OWRC), and striking Quad Blue Coated Tips (4xS11B).\n\nFitment is specified for the Audi A4 2.0 TFSI B9 2WD Non-OPF models from 2016 to 2021, including both Sedan and Avant body styles. It is also compatible with the Audi A4 Quattro from 2017 to 2019.","brand":"Audi","offers":[{"title":"Default Title","offer_id":52687010005304,"sku":"AU942-QS11B","price":2332.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660677282.png?v=1784879424","url":"https:\/\/store.motormia.co\/products\/valvetronic-exhaust-system-4","provider":"MOTORMIA","version":"1.0","type":"link"}
