{"product_id":"f87-axle-back-exhaust-system","title":"F87 Axle-Back Exhaust System","description":"The Active Autowerke F87 rear exhaust is a valved axle-back exhaust system engineered to replace the stock rear section of your BMW M2 Competition and M2 CS. It aims to eliminate the factory exhaust's unflattering sound and enhance the overall driving enjoyment. By reusing the factory BMW valve actuators, this system ensures optimum flow and resonance, delivering a deep, throaty growl worthy of an M car.\n\nIt features stock valve control, allowing you to maintain the original functionality of your vehicle's exhaust system. Each unit is meticulously test-fitted on an in-house F87 Exhaust Fixture to guarantee a precise fit. All necessary installation hardware is included to facilitate a smooth installation process.\n\nInstallation Note: If this rear exhaust is used with an Active Autowerke resonated midpipe, double-resonated connecting pipes may be necessary to reduce exhaust rasp. In such cases, the exhaust hangers must be flipped from the factory configuration (driver side to passenger and vice versa) and reversed for proper fitment. Double resonator connecting pipes are available upon special request with an additional charge.\n\nIt's important to note that Active Autowerke also offers a version of this rear exhaust for those intending to keep their stock midpipes. However, if you later decide to upgrade to an Active or other midpipe, there will be a subsequent charge for replacing the connecting pipes. Please specify your intended configuration when ordering.","brand":"Active Autowerke","offers":[{"title":"Default Title","offer_id":52686764081464,"sku":"11-067","price":2089.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661162944.webp?v=1784876458","url":"https:\/\/store.motormia.co\/products\/f87-axle-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
