uses a middle and rear silencer alongside a pair of exhaust valves, designed to be free-flowing while still meeting drive-by noise regulations. The rear silencer uses a reflection chamber on each side that redirects exhaust gases to the opposite side from where they entered (the driver's side exhaust exits on the passenger side), and when the valves are closed, this design helps manage backpressure buildup from noise dampening. The result, in practice, is a flat, buzzy tone that many owners describe as more \"weed eater\" than proper M car.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eAfter analysing the factory system, Active Autowerke concluded that less would be more, and built the Maad Maxx rear section around a complete redesign of that philosophy. The triple-canister muffler design delivers superior resonance control and reduced drone compared to the factory back box, while an optimised-flow axle-back layout complements the F8X platform's natural characteristics. Flex joints reduce vibration transfer, and the valved design gives you volume control exactly when you want it, aggressive and deep with the valves open, civil and refined when you need it. Every unit is test-fit on a dedicated F8X exhaust fixture, guaranteed to fit all F80 M3 and F82\/F83 M4 models, and comes with all necessary installation hardware.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e Best paired with Active Autowerke's F8X Midpipe for the deepest tone and full performance gains.

for maximum performance and sound, this is a complete catback exhaust system engineered specifically for the S55-powered F87 M2 Competition. The factory centre section uses a dual-pipe layout that both restricts flow and contributes to turbo lag. Active Autowerke's Signature System solves both problems at once, replacing it with a single 3.5in pipe that improves exhaust flow, sharpens turbo response, and delivers a deep, purposeful sound in its place.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eConstructed entirely from 100% SS304 stainless steel with full TIG welding throughout (never MIG), the 3.5in mandrel-bent design is engineered to handle power levels well beyond stock, making it just as suitable for a factory-spec M2 Competition as it is for heavily modified builds, including turbo upgrades. A carefully engineered Y-pipe layout, full 3.5in diameter, and integrated valve system deliver excellent flow while finally giving the M2 Competition the genuinely sporty exhaust note it was missing from the factory, while still retaining the ability to close the valves for quiet, everyday driving.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e OEM valve actuators.

It's a genuine bolt-on upgrade, engineered specifically around the G87's factory mounting points rather than adapted from another platform.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis axle-back is also the entry point into Active Autowerke's wider exhaust system for the G87, built on over 40 years of developing parts that improve both power and driving enjoyment. Paired with their GESI midpipe and downpipe, the combination delivers the strongest sound and performance gains available for this car. The axle-back alone already transforms the exhaust note noticeably, but if you want the valves-open sound to genuinely turn heads, adding the midpipe and downpipe makes the biggest difference of all.\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=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This Axle-Back Exhaust\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\"\u003eDesigned and engineered in the USA specifically for the G87 platform\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBuilt from high-grade SS304 stainless steel for genuine long-term durability\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRetains factory valve control, quiet for daily driving, aggressive on demand\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGuaranteed direct fitment for all G87 M2 models\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAll necessary mounting hardware included\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePairs seamlessly with Active Autowerke's GESI midpipe and downpipe for the complete sound and performance package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 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 G87 M2 Coupe (2023+)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection id=\"shopify-section-template--23383691428165__main\" class=\"shopify-section section\"\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 id=\"ProductInfo-template--23383691428165__main\" class=\"product__info-container product__column-sticky\"\u003e\n\u003cdiv class=\"product__description rte quick-add-hidden\"\u003e\n\u003csection id=\"shopify-section-template--23383691428165__main\" class=\"shopify-section section\"\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 id=\"ProductInfo-template--23383691428165__main\" class=\"product__info-container product__column-sticky\"\u003e\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"Active Autowerke","offers":[{"title":"Brushed Silver","offer_id":54423748641101,"sku":"AAW-SIL-S58-009","price":3333.79,"currency_code":"EUR","in_stock":true},{"title":"Matte Black","offer_id":54423748673869,"sku":"AAW-SIL-S58-009","price":3460.84,"currency_code":"EUR","in_stock":true},{"title":"Carbon Fibre","offer_id":54423748706637,"sku":"AAW-SIL-S58-009","price":4096.09,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/active-autowerke-bmw-g87-m2-valved-rear-axle-back-exhaust.jpg?v=1785789161"}],"url":"https:\/\/i6tuning.com\/collections\/out-of-stock-active-autowerke.oembed","provider":"i6 Tuning","version":"1.0","type":"link"}
