But they overcorrected, making the driver's side exhaust longer than the passenger side, leaving the factory system still imbalanced. Active Autowerke's patented Signature Equal Length Midpipe corrects the passenger side exhaust length specifically, giving the G80 M3 and G82 M4 a genuinely true equal-length system and a smoother sound.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis brings the same expertise developed for the F8X M cars to the G8X platform, offered as one of three midpipe choices alongside the Single and X-Pipe versions. Gen 2 introduces specially developed resonators, engineered to remove rasp from the exhaust tone with minimal change in overall volume, alongside a genuine reduction in the \"2k buzzing\" some owners find annoying and less cold-start rattle from the factory system. The equal-length technology itself is protected by US Patent 11248511 and EU\/UK Patent 3882441, genuinely unique engineering rather than a generic aftermarket solution. Constructed from 100% 304 brushed stainless steel with an industry-standard warranty against rust, the system installs with only two cuts needed in the stock midpipe, remaining a bolt-on that most can perform, with the stock midpipe reinstallable if ever needed. It includes the Active G-Brace as standard.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This Equal Length Midpipe\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePatented equal-length design (US Patent 11248511, EU\/UK Patent 3882441)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGen 2 resonators reduce rasp and \"2k buzzing\" versus the original Gen 1 design\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCorrects BMW's own imperfect factory equal-length attempt\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eIncludes the Active Autowerke G-Brace as standard\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e100% 304 brushed stainless steel, industry-standard warranty against rust\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBolt-on installation, only two cuts needed in the stock midpipe\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFully reversible, stock midpipe can be reinstalled if needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eCompatibility\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW G80 M3 Sedan (S58)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW G81 M3 Touring (S58)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW G82 M4 Coupe (S58)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW G83 M4 Cabriolet (S58)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection class=\"shopify-section section\" id=\"shopify-section-template--23383691428165__main\"\u003e\n\u003cdiv class=\"page-width\"\u003e\n\u003cdiv class=\"product product--small product--left product--thumbnail_slider product--mobile-show grid grid--1-col grid--2-col-tablet\"\u003e\n\u003cdiv class=\"product__info-wrapper grid__item product__info-wrapper--extra-padding scroll-trigger animate--slide-in\"\u003e\n\u003csection class=\"product__info-container product__column-sticky\" id=\"ProductInfo-template--23383691428165__main\"\u003e\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"Active Autowerke","offers":[{"title":"Gen 2 - Non Resonated","offer_id":54423744282957,"sku":"AAW-MPS-S58-017-G2N","price":2334.03,"currency_code":"EUR","in_stock":false},{"title":"Gen 2 - Resonated","offer_id":54423744315725,"sku":"AAW-MPS-S58-017-G2R","price":2576.03,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Active-Autowerke-BMW-g80-g81-g82-g83-M3-M4-Equal-Length-Midpipe.webp?v=1785350324","url":"https:\/\/i6tuning.com\/products\/active-autowerke-bmw-m3-m4-g80-g81-g82-g83-equal-length-midpipe","provider":"i6 Tuning","version":"1.0","type":"link"}
