Constructed 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eUnlike a full de-cat pipe, this configuration retains genuine catalytic converter function, a sensible choice for owners wanting improved flow while staying closer to emissions compliance than a straight-through pipe. Reducing restriction at the catalytic converter stage is one of the more meaningful upgrades available on this twin-turbo V6 platform, letting the engine breathe more freely without stepping into full de-cat territory.\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\u003eSpecifically engineered for OPF\/GPF-equipped models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAudi RS4 (B9) 2.9 V6 Turbo Avant, OPF\/GPF Models\u003c\/li\u003e\n\u003cli\u003eAudi RS5 (B9) 2.9 V6 Turbo, OPF\/GPF Models\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":54638952808781,"sku":"SSXAU819","price":4722.68,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_RS4_B9_2.9_V6_Turbo_Avant_OPF_GPF_Hi-Flow_Sports_Cats.webp?v=1788467182","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs4-rs5-b9-2-9-v6-turbo-avant-opf-gpf-hi-flow-sports-cats","provider":"i6 Tuning","version":"1.0","type":"link"}
