The D4 S8's twin-turbo V8 is genuinely one of the more understated performance flagships Audi has built, and this upgrade is engineered to let it breathe more freely without sacrificing the car's inherently refined character.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eConstructed from T-304 stainless steel throughout, these sports cats are built to outlast the factory components they replace, resisting the corrosion that eventually catches up with mild steel factory parts. Reducing restriction at the catalytic converter stage is one of the more meaningful upgrades available on this platform, letting the engine breathe more freely without stepping into full de-cat territory or sacrificing the S8's genuine daily-driver refinement.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy Choose These Hi-Flow Sports Cats\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eGenuinely higher flow capacity than the restrictive factory catalytic converters\u003c\/li\u003e\n\u003cli\u003eRetains meaningful catalytic converter function, unlike a full de-cat pipe\u003c\/li\u003e\n\u003cli\u003eT-304 stainless steel construction, built for long-term durability\u003c\/li\u003e\n\u003cli\u003ePreserves the S8's genuinely refined daily-driver character\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eCompatibility\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eAudi S8 (D4) 4.0 TFSI Quattro\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":54701663289677,"sku":"SSXAU953","price":5712.76,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_S8_D4_4.0_TFSI_Quattro_Hi-Flow_Sports_Cats.webp?v=1789027001","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-s8-d4-4-0-tfsi-quattro-hi-flow-sports-cats","provider":"i6 Tuning","version":"1.0","type":"link"}
