On a genuinely potent platform like the S58-powered M3\/M4, the factory OPF\/GPF represents a real bottleneck in the exhaust system, and removing it delivers a noticeable improvement in flow and turbo response.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis Non-Resonated configuration delivers a louder, more unfiltered exhaust note than a resonated equivalent, without a resonator chamber to soften the tone. Constructed from T-304 stainless steel throughout for long-term durability. Intended primarily for track and off-road use, worth checking local emissions regulations before fitting to a road car, since removing the particulate filter entirely will affect emissions compliance in most regions.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlease select your fitment at checkout:\u003c\/strong\u003e Fits to OE System or Fits to Milltek Sport System, depending on whether you're retaining the factory exhaust downstream or already running a Milltek system.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy Choose This OPF\/GPF Bypass Mid Section\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eRemoves a significant restriction point in the S58's factory exhaust entirely\u003c\/li\u003e\n\u003cli\u003eNon-Resonated design, genuinely louder and more unfiltered than a resonated equivalent\u003c\/li\u003e\n\u003cli\u003eT-304 stainless steel construction, built for long-term durability\u003c\/li\u003e\n\u003cli\u003eAvailable matched to either OE or Milltek Sport downstream systems\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 (G80\/G81)\u003c\/li\u003e\n\u003cli\u003eBMW M4 (G82\/G83)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Fits to OE System","offer_id":54706965905741,"sku":"SSXBM1194","price":1061.86,"currency_code":"EUR","in_stock":false},{"title":"Fits to Milltek Sport System","offer_id":54706965938509,"sku":"SSXBM1196","price":1061.86,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Milltek_Sport_BMW_M3_M4_G80_G81_G82_G83_Non-Resonated_OPF_GPF_Bypass_Mid_Section.webp?v=1789050666","url":"https:\/\/i6tuning.com\/products\/milltek-sport-bmw-m3-m4-g80-g81-g82-g83-non-resonated-opf-gpf-bypass-mid-section","provider":"i6 Tuning","version":"1.0","type":"link"}
