Milltek Sport's Cat-Back exhaust replaces everything from the catalytic converter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eConstructed entirely from T-304 stainless steel, this system is built to outlast the car itself, resisting the corrosion that eventually catches up with mild steel factory systems, especially through wet European winters. Milltek's own sound engineers spend considerable time tuning each system's resonance and tone, striking a genuine balance between letting this twin-turbo V8 sound properly purposeful and avoiding the drone that can plague poorly engineered aftermarket systems on a long motorway drive.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlease select your type at checkout:\u003c\/strong\u003e Resonated (the most refined, restrained everyday character) or Non-Resonated (noticeably louder and more aggressive).\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy Choose This Exhaust System\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eGenuine gains in flow, sound, and weight over the factory system\u003c\/li\u003e\n\u003cli\u003eT-304 stainless steel construction throughout, built to outlast the factory system\u003c\/li\u003e\n\u003cli\u003eMilltek's own sound engineering, letting the twin-turbo V8 sound properly purposeful\u003c\/li\u003e\n\u003cli\u003eChoice of Resonated or Non-Resonated 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":"Resonated","offer_id":54682980483405,"sku":"SSXAU364","price":3497.46,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated","offer_id":54682980516173,"sku":"SSXAU365","price":3233.73,"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_Cat-Back_Exhaust_System.webp?v=1788855150","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs6-rs7-c7-4-0-tfsi-bi-turbo-quattro-cat-back-exhaust-system","provider":"i6 Tuning","version":"1.0","type":"link"}
