This is a sensible middle-ground option for owners wanting a substantial flow improvement without going the full de-cat route.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eConstructed from T-304 stainless steel throughout, this system is built to outlast the factory components it replaces, resisting the corrosion that eventually catches up with mild steel factory parts. Reducing backpressure across both the downpipe and catalytic converter sections at once delivers a more complete performance upgrade than addressing either section individually, particularly noticeable when paired with a supporting ECU tune.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy Choose These Downpipes and Hi-Flow Sports Cats\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eCombines larger-bore downpipes with higher-flow sports cats in one package\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 throughout, built for long-term durability\u003c\/li\u003e\n\u003cli\u003eParticularly effective when paired with a supporting ECU tune\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 RS6 (C7) 4.0 TFSI Bi-Turbo Quattro\u003c\/li\u003e\n\u003cli\u003eAudi RS7 (C7) 4.0 TFSI Bi-Turbo Quattro\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":54682980024653,"sku":"SSXAU554","price":4910.8,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_RS6_RS7_C7_4.0_TFSI_Bi-Turbo_Quattro_Large_Bore_Downpipes_and_Hi-Flow_Sports_Cats.webp?v=1788854301","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs6-rs7-c7-4-0-tfsi-bi-turbo-quattro-large-bore-downpipes-and-hi-flow-sports-cats","provider":"i6 Tuning","version":"1.0","type":"link"}
