Milltek Sport's Cat-Back exhaust for the OPF\/GPF-equipped M3\/M4 replaces everything from the catalytic converter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system while retaining the OPF\/GPF unit itself for continued emissions compliance.\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, sporting 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 and exhaust tip finish at checkout:\u003c\/strong\u003e Road (a more refined, everyday-focused tune) or Race (a genuinely sportier, more aggressive tune, best suited to track use), each in a choice of Polished, Cerakote Black, Brushed Titanium, Burnt Titanium, or Carbon Fibre finish.\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\u003eRetains the OPF\/GPF unit for continued emissions compliance\u003c\/li\u003e\n\u003cli\u003eChoice of Road or Race tune, each with five tip finish options\u003c\/li\u003e\n\u003cli\u003eMilltek's own sound engineering, avoiding unwanted drone\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\u003eBMW M3 (F80), OPF\/GPF\u003c\/li\u003e\n\u003cli\u003eBMW M4 (F82\/F83), OPF\/GPF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Road \/ Polished","offer_id":54710266298701,"sku":"SSXBM1126","price":2710.34,"currency_code":"EUR","in_stock":false},{"title":"Road \/ Cerakote Black","offer_id":54710266331469,"sku":"SSXBM1125","price":2939.3,"currency_code":"EUR","in_stock":false},{"title":"Road \/ Brushed Titanium","offer_id":54710266364237,"sku":"SSXBM1124","price":3335.33,"currency_code":"EUR","in_stock":false},{"title":"Road \/ Burnt Titanium","offer_id":54710266397005,"sku":"SSXBM1123","price":3586.56,"currency_code":"EUR","in_stock":false},{"title":"Road \/ Carbon Fibre","offer_id":54710266429773,"sku":"SSXBM1122","price":3022.22,"currency_code":"EUR","in_stock":false},{"title":"Race \/ Polished","offer_id":54710266462541,"sku":"SSXBM1117","price":2710.34,"currency_code":"EUR","in_stock":false},{"title":"Race \/ Cerakote Black","offer_id":54710266495309,"sku":"SSXBM1118","price":2939.3,"currency_code":"EUR","in_stock":false},{"title":"Race \/ Brushed Titanium","offer_id":54710266528077,"sku":"SSXBM1119","price":3335.33,"currency_code":"EUR","in_stock":false},{"title":"Race \/ Burnt Titanium","offer_id":54710266560845,"sku":"SSXBM1120","price":3586.56,"currency_code":"EUR","in_stock":false},{"title":"Race \/ Carbon Fibre","offer_id":54710266593613,"sku":"SSXBM1121","price":3022.22,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_BMW_M3_M4_F80_F82_F83_OPF_GPF_Cat-Back_Exhaust_System.webp?v=1789120659","url":"https:\/\/i6tuning.com\/products\/milltek-sport-bmw-m3-m4-f80-f82-f83-opf-gpf-cat-back-exhaust-system","provider":"i6 Tuning","version":"1.0","type":"link"}
