{"product_id":"4-stainless-steel-downpipe","title":"4\" Stainless Steel Downpipe","description":"The CTS Turbo B46 Downpipe is engineered to enhance the performance of your 2015+ Mini Cooper S (F54, F55, F56, F57, F60) and compatible BMW models (F48 X1\/X2, F44 228i) equipped with the B46 engine. This direct bolt-on upgrade significantly reduces exhaust restriction, leading to notable power and torque gains. It is constructed from 100% stainless steel with precise TIG welds for durability and quality, featuring a 4\" mandrel-bent piping for optimal flow. A precision CNC-machined V-Band flange ensures a secure connection, while the integrated stainless steel flex section provides factory-like movement and flexibility.\n\nIt offers an average horsepower increase of 14 to 16 whp and torque gains of 20 wtq at stock boost, which can exceed 24 wtq with a software upgrade. Users can expect a higher overall power curve, improved initial torque, better throttle response, and faster turbo spool-up times. These performance enhancements are achieved through the downpipe's mandrel-bent 4\" piping, maximizing exhaust flow.\n\nIt is crucial to note that this downpipe does NOT fit JCW (John Cooper Works) models due to a different exhaust connection. Furthermore, proper software tuning is REQUIRED to prevent Check Engine Lights (CELs) after installation. The precise fitment list includes: MINI Cooper S Hardtop F56 (2014-2020), MINI Cooper S Hardtop 4 door F55 (2015-2020), MINI Cooper S convertible F57 (2016-2020), MINI Cooper S Clubman F54 (2016-2020), MINI Cooper S Countryman F60 (2017-2022), BMW X1 F48 (2016-2021), BMW X2 F48 (2018-2021), and BMW 228i F44 (2019-2020).","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52687539208504,"sku":"CTS-EXH-DP-0036","price":297.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663677334.jpg?v=1784884982","url":"https:\/\/store.motormia.co\/products\/4-stainless-steel-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
