{"product_id":"high-flow-middle-exhaust-2","title":"High Flow Middle Exhaust","description":"The Dinan High Flow Middle Exhaust is engineered to provide a more aggressive and voluminous sound for the 2018-2023 BMW M550i xDrive. This mid-pipe replaces the factory's hydro-formed center section and resonator with larger, 3-inch diameter T304 stainless steel tubing, promoting freer-flowing exhaust gases.\n\nAt the heart of this system is a meticulously crafted X-pipe crossover, constructed from mandrel-bent tubing. This design minimizes restriction and helps to create a smoother, fuller, and more aggressive exhaust note by promoting even flow to both banks of the exhaust tips and eliminating unwanted sound nuances. The use of 100% 304 stainless steel construction ensures durability and corrosion resistance.\n\nThe manufacturer states that this part is legal for sale or use on all emissions-controlled, uncontrolled, and racing vehicles as it does not affect vehicle emissions. However, it is confirmed to fit only with the Dinan Free Flow Axle Back and stock exhaust systems; fitment with other axle-back units is not guaranteed.","brand":"Dinan","offers":[{"title":"Default Title","offer_id":52860283355448,"sku":"D660-0080-DINAN","price":1162.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687896390_8e45aae4-0f28-4df6-ad1e-f354b3fd996a.jpg?v=1787766443","url":"https:\/\/store.motormia.co\/products\/high-flow-middle-exhaust-2","provider":"MOTORMIA","version":"1.0","type":"link"}
