{"product_id":"muffler-torque-converter-software-upgrade-kit","title":"Muffler Torque Converter Software Upgrade Kit","description":"This kit includes a specially designed M Performance muffler, a torque converter repair kit compatible with the GA8HP50 transmission, and an M Performance decal kit, along with stick-on labels and badges. The package also comes with a Performance BMW software upgrade code.\n\nUpon installation, an immediate improvement in performance is noticeable, particularly in the low to mid-range powerband, resulting in an increase to 355hp and 369 ft-lb of torque. To complete the installation, the included software upgrade code must be taken to a BMW dealer for an ECU re-flash. It's important to note that chrome exhaust tips are sold separately (part number 18302444529). Additionally, vehicles equipped with the M Sport Package (337A) or M Aero Package (715A) will require the M 550i diffuser (part number 51128067763), while vehicles without these packages will need the bumper cutout trim set (part number 51122447338); both are sold separately.","brand":"M Performance","offers":[{"title":"Default Title","offer_id":52663056826680,"sku":"11122444214","price":2553.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687512834.jpg?v=1784323317","url":"https:\/\/store.motormia.co\/products\/muffler-torque-converter-software-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
