Milltek Sport's Cat-Back exhaust for the Avant replaces everything from the catalytic converter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system, specifically for non-OPF\/GPF models spanning 2018-2025.\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 V6 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 and tip finish at checkout:\u003c\/strong\u003e twelve configurations available, spanning Road + Resonated, Resonated, Non-Resonated, and Race Non-Resonated tunes, each in a choice of Polished, Cerakote Black, Titanium, or Burnt Titanium oval tips (availability of specific finishes varies by tune type).\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\u003eTwelve configurations spanning four sound profiles and four tip finishes\u003c\/li\u003e\n\u003cli\u003eMilltek's own sound engineering, letting the twin-turbo V6 sound properly purposeful\u003c\/li\u003e\n\u003cli\u003eSpecifically engineered for non-OPF\/GPF models, 2018-2025\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 (B9) 2.9 V6 Turbo Avant, Non-OPF\/GPF, 2018-2025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Road + Resonated \/ Polished Oval Tips","offer_id":54638952120653,"sku":"SSXAU759","price":3598.94,"currency_code":"EUR","in_stock":false},{"title":"Road + Resonated \/ Cerakote Black Oval Tips","offer_id":54638952022349,"sku":"SSXAU760","price":3749.93,"currency_code":"EUR","in_stock":false},{"title":"Road + Resonated \/ Titanium Oval Tips","offer_id":54638952055117,"sku":"SSXAU807","price":3985.07,"currency_code":"EUR","in_stock":false},{"title":"Road + Resonated \/ Burnt Titanium Oval Tips","offer_id":54638952087885,"sku":"SSXAU808","price":4093.98,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated \/ Cerakote Black Oval Tips","offer_id":54638952218957,"sku":"SSXAU751","price":3912.05,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated \/ Titanium Oval Tips","offer_id":54638952186189,"sku":"SSXAU803","price":4087.79,"currency_code":"EUR","in_stock":false},{"title":"Non-Resonated \/ Burnt Titanium Oval Tips","offer_id":54638952153421,"sku":"SSXAU804","price":4162.05,"currency_code":"EUR","in_stock":false},{"title":"Resonated \/ Polished Oval Tips","offer_id":54638952317261,"sku":"SSXAU749","price":4169.47,"currency_code":"EUR","in_stock":false},{"title":"Resonated \/ Cerakote Black Oval Tips","offer_id":54638952350029,"sku":"SSXAU750","price":4320.46,"currency_code":"EUR","in_stock":false},{"title":"Resonated \/ Titanium Oval Tips","offer_id":54638952284493,"sku":"SSXAU805","price":4555.61,"currency_code":"EUR","in_stock":false},{"title":"Resonated \/ Burnt Titanium Oval Tips","offer_id":54638952251725,"sku":"SSXAU806","price":4664.51,"currency_code":"EUR","in_stock":false},{"title":"Race Non-Resonated \/ Polished Oval Tips","offer_id":54638952382797,"sku":"SSXAU752","price":3783.34,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_Audi_RS4_B9_2.9_V6_Turbo_Avant_Non-OPF_GPF_2018-2025_Cat-Back_Exhaust_System.webp?v=1788466751","url":"https:\/\/i6tuning.com\/products\/milltek-sport-audi-rs4-b9-2-9-v6-turbo-avant-non-opf-gpf-2018-2025-cat-back-exhaust-system","provider":"i6 Tuning","version":"1.0","type":"link"}
