This combination targets two of the most restrictive points in the factory exhaust system at once, delivering a substantial flow improvement over addressing either section individually.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eReducing backpressure at both the downpipe and catalytic converter stages simultaneously typically delivers one of the most noticeable power and response gains available on this twin-turbo V8 platform, particularly when paired with a supporting ECU tune. Intended primarily for track and off-road use, worth checking local emissions regulations before fitting to a road car, since removing catalytic converter function entirely will affect emissions compliance in most regions.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlease select your fitment at checkout:\u003c\/strong\u003e Fits to OE System or Fits to Milltek Sport System, depending on whether you're retaining the factory exhaust downstream or already running a Milltek system.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy Choose These Downpipes and Cat Bypass Pipes\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eGenuinely larger diameter than the factory downpipes, reducing backpressure throughout\u003c\/li\u003e\n\u003cli\u003eTargets both the downpipe and catalytic converter restriction points at once\u003c\/li\u003e\n\u003cli\u003eT-304 stainless steel construction, built for long-term durability\u003c\/li\u003e\n\u003cli\u003eAvailable matched to either OE or Milltek Sport downstream systems\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 (C8) 4.0 V8 Bi-Turbo, OPF\/GPF Models\u003c\/li\u003e\n\u003cli\u003eAudi RS7 (C8) 4.0 V8 Bi-Turbo, OPF\/GPF Models\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Fits to OE System","offer_id":54701663158605,"sku":"SSXAU871","price":3733.84,"currency_code":"EUR","in_stock":false},{"title":"Fits to Milltek Sport System","offer_id":54701663191373,"sku":"SSXAU870","price":3754.88,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_RS6_RS7_C8_4.0_V8_Bi-Turbo_OPF_GPF_Large-Bore_Downpipes_and_Cat_Bypass_Pipes_1.webp?v=1789026551","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs6-rs7-c8-4-0-v8-bi-turbo-opf-gpf-large-bore-downpipes-and-cat-bypass-pipes","provider":"i6 Tuning","version":"1.0","type":"link"}
