{"product_id":"evolution-line-cat-back-exhaust-system-2","title":"Evolution Line Cat Back Exhaust System","description":"This system is meticulously engineered to provide an intoxicating and refined exhaust note for the 2020+ Audi RS6 Avant (C8), delivering a deep, sporty sound reminiscent of a muscle car without any undesirable drone. The exhaust system retains the factory valve systems, offering compatibility with the Akrapovic Sound Kit for adjustable valve control and sound mode selection.\n\nAkrapovic's development process involves extensive testing and refinement, utilizing 3D CAD\/CAM environments, CAE simulations, and chassis dyno evaluations to optimize structural rigidity, thermal loads, torque, and power. The NVH (noise, vibration, and harshness) engineering team carefully tunes each component to achieve the perfect balance between a sporty character and a comfortable driving experience. Prototypes undergo rigorous on-road tests, dyno testing, and acoustic analysis to achieve sound perfection, supported by objective sound engineering data.\n\nThis Evolution Line exhaust system is designed to complement the C8 RS6 Avant's performance, enhancing its aural character. It is offered with stylish carbon-fiber or titanium tips to further customize the vehicle's aesthetics. Note that this system requires the Akrapovic Link Pipes (Part Number: L-AU\/SS\/6) for installation.","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":52686876606776,"sku":"S-AU\/TI\/15H-AKRA","price":9977.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660181391.webp?v=1784877894","url":"https:\/\/store.motormia.co\/products\/evolution-line-cat-back-exhaust-system-2","provider":"MOTORMIA","version":"1.0","type":"link"}
