{"product_id":"free-flow-axle-back-exhaust","title":"Free Flow Axle-Back Exhaust","description":"The Dinan Free Flow Axle-Back Exhaust is engineered to enhance the performance and sound of the BMW F22 228i. By reducing back pressure, this exhaust system improves flow, resulting in a modest power increase of 4 horsepower and 3 ft-lbs of torque. The system is constructed from 100% 16-gauge 304 stainless steel, ensuring durability and resistance to corrosion. It features twin 70 mm (2.75\") exhaust tips, available in ceramic black or polished stainless steel, which are laser engraved for a high-performance aesthetic. The factory computer-controlled exhaust valve is eliminated with this upgrade. Installation is straightforward with a simple bolt-on design utilizing factory brackets and hangers, and includes the necessary mounting hardware. Fitment is not guaranteed for vehicles equipped with the M-Aerodynamic rear bumper, as it has not yet been tested for compatibility.","brand":"Dinan Free","offers":[{"title":"Default Title","offer_id":52687700590904,"sku":"D660-0052-BLK","price":891.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663680385.jpg?v=1784886294","url":"https:\/\/store.motormia.co\/products\/free-flow-axle-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
