{"product_id":"milltek-sport-audi-rs5-b8-cat-back-exhaust-system","title":"Milltek Sport Audi RS5 B8 Cat-Back Exhaust System","description":"\u003cp dir=\"ltr\"\u003eThe B8 RS5's naturally-aspirated 4.2-litre FSI V8 is genuinely a high-revving, characterful engine, and the factory exhaust leaves real drama on the table, tuned as much around noise regulations as outright sound. 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 type at checkout:\u003c\/strong\u003e Resonated (the most refined, restrained everyday character), Non-Resonated (noticeably louder and more aggressive), or US-Spec (a dedicated configuration engineered for the US-market RS5).\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 this naturally-aspirated V8 sing properly\u003c\/li\u003e\n\u003cli\u003eDedicated US-Spec configuration available for the US-market RS5\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 RS5 (B8) Coupé\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Resonated","offer_id":54638954250573,"sku":"SSXAU267","price":3464.04,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated","offer_id":54638954283341,"sku":"SSXAU334","price":3252.41,"currency_code":"EUR","in_stock":false},{"title":"US-Spec","offer_id":54638954316109,"sku":"SSXAU335","price":2913.31,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_RS5_B8_Cat-Back_Exhaust_System.webp?v=1788510562","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs5-b8-cat-back-exhaust-system","provider":"i6 Tuning","version":"1.0","type":"link"}
