{"product_id":"valvetronic-exhaust-system-with-ecu-control","title":"Valvetronic Exhaust System with ECU Control","description":"The FI Exhaust valvetronic exhaust system for the Audi B8 S4 Sedan\/Avant and S5 Sportback (2009-2015, 3.0TFSI) is engineered for an exhilarating soundtrack and improved performance. Constructed from premium T304 stainless steel, this system offers a direct bolt-on replacement.\n\nAt its core is the Frequency Intelligent (FI) Valvetronic technology, which meticulously controls airflow and sound volume. This allows for a seamless transition between comfort and performance. When the valves are closed, exhaust gases are routed through the muffler for a quiet, low-profile drive, ideal for everyday use. Upon opening, the valves unleash an intense, sporty tone and maximize exhaust flow for enhanced performance.\n\nThis system offers customizable sound profiles and performance characteristics. Users can opt for different control methods, including a factory exhaust\/sport button, drive modes, or the optional Fi Pro remote control upgrade. Please note that some options and features may vary by specific car model and configuration; consult with a representative for confirmation. Optional accessories like remote controls and various tip finishes are available to further personalize the system.","brand":"FI Exhaust","offers":[{"title":"Default Title","offer_id":52688148791608,"sku":"AD-S4-CBV + TIP6389S*4+R2016OL+OBD-CAB-V","price":3600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664709513.webp?v=1784889040","url":"https:\/\/store.motormia.co\/products\/valvetronic-exhaust-system-with-ecu-control","provider":"MOTORMIA","version":"1.0","type":"link"}
