{"product_id":"valvetronic-cat-back-exhaust-system-stainless-steel","title":"Valvetronic Cat-Back Exhaust System, Stainless Steel","description":"The Armytrix valvetronic catback exhaust system is engineered to enhance the performance and acoustic profile of 2016-2021 Audi A5 2.0 TFSI B9 and A5 Sportback 2.0 TFSI B9 vehicles.\n\nKey to this system is the specialized valvetronic technology, which features throttle pedal sensor and engine RPM signal integration. At lower RPMs, the valves remain closed to maintain necessary backpressure for improved launch-start performance. Under higher RPMs or heavy throttle, the valves open to provide a high-flow straight-pipe path that maximizes horsepower and torque while producing a aggressive race-inspired sound. Users can customize valve operation settings based on engine load.\n\nInstallation includes the hardware required to integrate with the vehicle's signal systems. This valvetronic design is aimed at neutralizing annoying drone-inducing frequencies during normal operation while providing full sound output during race mode.","brand":"Armytrix","offers":[{"title":"Default Title","offer_id":52689682891064,"sku":"AU952-QC11","price":3897.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687546401.webp?v=1784909138","url":"https:\/\/store.motormia.co\/products\/valvetronic-cat-back-exhaust-system-stainless-steel","provider":"MOTORMIA","version":"1.0","type":"link"}
