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, letting this naturally-aspirated V8 sing the way it genuinely deserves to.\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 a purposeful V8 character and everyday drivability, 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 configuration at checkout:\u003c\/strong\u003e Resonated or Non-Resonated, each available in Valved or Non-Valved form, and in either Polished (round or oval) or Satin Sheep Black tip finish.\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eValved\u003c\/strong\u003e versions let you control the exhaust character further, opening up under load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Valved\u003c\/strong\u003e versions offer a fixed, consistent character throughout the rev range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\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\u003eValved options for further control over exhaust character under load\u003c\/li\u003e\n\u003cli\u003eMilltek's own sound engineering, letting this naturally-aspirated V8 sing properly\u003c\/li\u003e\n\u003cli\u003eChoice of Polished or Satin Sheep Black tip finish\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 (B7) 4.2 V8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Resonated Valved Polished Oval Tips","offer_id":54638951137613,"sku":"SSXAU061","price":3236.32,"currency_code":"EUR","in_stock":false},{"title":"Resonated Valved Satin Sheep Black Tips","offer_id":54638951170381,"sku":"SSXAU221","price":3373.7,"currency_code":"EUR","in_stock":false},{"title":"Resonated Non-Valved Polished Oval Tips","offer_id":54638951203149,"sku":"SSXAU060","price":2199.22,"currency_code":"EUR","in_stock":false},{"title":"Resonated Non-Valved Satin Sheep Black Tips","offer_id":54638951235917,"sku":"SSXAU060BLK","price":2266.05,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated Valved Polished Tips","offer_id":54638951268685,"sku":"SSXAU116","price":2909.6,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated Valved Satin Sheep Black Tips","offer_id":54638951301453,"sku":"SSXAU218","price":3046.97,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated Non-Valved Polished Tips","offer_id":54638951334221,"sku":"SSXAU117","price":1872.49,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated Non-Valved Satin Sheep Black Tips","offer_id":54638951366989,"sku":"SSXAU062BLK","price":1939.32,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_RS4_B7_4.2_V8_Cat-Back_Exhaust_System.webp?v=1788465034","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs4-b7-4-2-v8-cat-back-exhaust-system","provider":"i6 Tuning","version":"1.0","type":"link"}
