Active Autowerke's Valved Rear Axle-Back Exhaust was developed specifically to solve this, carefully engineered to increase sound level over the factory system while maintaining optimum flow and resonance, reusing the actuators from the factory BMW valves in the process.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eBuilt from 304 stainless steel, this axle-back delivers a deep, aggressive tone while maintaining optimal flow, engineered for a precise, direct fit. It's designed as part of a complete exhaust system for the F97\/F98 platform, comprising this rear section, a single (or equal-length) midpipe, and a set of GESI catted downpipes. Together, this remake of the stock exhaust gives the X3M\/X4M the sound it should have had from the factory, genuinely restoring the true M-car driving experience these SUVs deserve.\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 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\"\u003eEngineered specifically to address the X3M\/X4M's overly quiet factory exhaust\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReuses the factory valve actuators, no aftermarket electronics required\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e304 stainless steel construction for genuine durability\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePrecisely engineered for a direct, accurate fit\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eA rear-section-only version is available for those wanting to keep the stock midpipe\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 F97 X3M (2019+)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F98 X4M (2019+)\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":54423746150733,"sku":"AAW-SIL-S58-005","price":3333.79,"currency_code":"EUR","in_stock":false},{"title":"Matte Black","offer_id":54423746183501,"sku":"AAW-SIL-S58-005","price":3460.84,"currency_code":"EUR","in_stock":false},{"title":"Carbon Fibre","offer_id":54423746216269,"sku":"AAW-SIL-S58-005","price":4096.09,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/Active-Autowerke-BMW-f97-x3m-axle-back.jpg?v=1785350330","url":"https:\/\/i6tuning.com\/products\/active-autowerke-bmw-x3m-x4m-f97-f98-valved-rear-axle-back-exhaust","provider":"i6 Tuning","version":"1.0","type":"link"}
