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":51733245788481,"sku":"GFBV_D660-0036-BLK","price":3342.65,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/1289\/6321\/files\/d660-0036-blk_1.jpg?v=1778898697","url":"https:\/\/sandmdiesel.com\/products\/dinan-free-flow-axle-back-exhaust-2011-2016-bmw-550i-d660-0036-blk","provider":"S\u0026M Diesel","version":"1.0","type":"link"}
