{"product_id":"axle-back-exhaust-system-quad-90mm-round-tips","title":"Axle-Back Exhaust System Quad 90mm Round Tips","description":"The Eisenmann Stainless Steel Axleback Exhaust system is a premium, hand-built performance upgrade for the BMW 640i F06, F12, and F13 models manufactured between 2013 and 2019.\n\nConstructed entirely from lightweight T304\/T306 stainless steel, both externally and internally, this exhaust system exemplifies old-world craftsmanship. The design, from tube configuration and muffler dimensions to the quad 90mm round exhaust tips, is meticulously calculated and optimized for enhanced power and sound. The system includes all necessary clamps for a slip-on installation, although cutting of the factory exhaust system is required, and modifications to the rear bumper may be necessary.\n\nEisenmann offers this axle-back system in two sound levels: Sport and Race. While specific performance gains are not listed, the meticulous engineering focuses on optimizing exhaust flow and acoustics for a noticeable improvement in the driving experience.","brand":"Eisenmann","offers":[{"title":"Default Title","offer_id":52687932752184,"sku":"B5429.00904","price":2680.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663171187.jpg?v=1784887695","url":"https:\/\/store.motormia.co\/products\/axle-back-exhaust-system-quad-90mm-round-tips","provider":"MOTORMIA","version":"1.0","type":"link"}
