Crafted from premium T304 stainless steel with a 2.5-inch diameter, this component is designed for direct fitment, ensuring seamless integration with OEM or Milltek cat-back exhaust systems.\n\nAt the heart of this downpipe is a high-flow sports catalytic converter featuring 200 CPSI (cells per square inch). This component optimizes exhaust flow, leading to increased engine efficiency and noticeable gains in horsepower and torque, along with a greatly improved turbo response compared to factory restrictive downpipes. Milltek is a renowned name in performance exhaust systems, built on decades of experience and a commitment to quality and innovation.\n\nThis downpipe is compatible with Audi S4 B9 (2017-2019) 3.0T, S4 B9.5 (2020-2024) 3.0T, S5 B9 (2018-2019) Coupe and Sportback 3.0T, and S5 B9.5 (2020-2025) Coupe and Sportback 3.0T models. It is designed to be used with Milltek's 3-inch cat-back exhausts, though other brands may require modification for fitment. A 2-year or 50,000-mile warranty is provided for hi-flow sports catalysts and downpipes when used in conjunction with other Milltek products.\n\nNote: This product is not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.","brand":"Milltek","offers":[{"title":"Default Title","offer_id":52689135796536,"sku":"SSXAU673","price":2234.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687764332.webp?v=1784902366","url":"https:\/\/store.motormia.co\/products\/3-0t-2-5-inch-high-flow-downpipe-with-200-cpsi-cat","provider":"MOTORMIA","version":"1.0","type":"link"}
