A vacuum controlled butterfly valve is utilized to improve flow at wide-open throttle while keeping things civilized and \"drone\" free throughout. The design reduces overall weight as well and features 3.5'' polished, or ceramic black, tips for a tasteful high-performance look.","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50689342210363,"sku":"GFBV_D660-0036","price":2254.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/8438\/2523\/files\/d660-0036_1.jpg?v=1761876342","url":"https:\/\/shop.apexracinglab.com\/products\/dinan-free-flow-axle-back-exhaust-2011-2016-bmw-550i","provider":"Apex Racing Lab","version":"1.0","type":"link"}
