{"product_id":"5-inch-downpipe-back-exhaust-system","title":"5-Inch Downpipe-Back Exhaust System","description":"The Flo Pro 680NM is a 5-inch downpipe-back exhaust system specifically engineered for 2017-2019 L5P 6.6L Duramax Chevrolet and GMC trucks.\n\nThe 5-inch piping is intended to improve torque, enhance exhaust flow, lower Exhaust Gas Temperatures (EGTs), and potentially improve fuel mileage.\n\n**Important Fitment and Installation Notes:**\n\n*   This kit is compatible with all wheelbase and cab configurations for the specified years and engine, provided the vehicle is equipped with the OEM-style 4-bolt flange off the turbo direct pipe. It is not compatible with models using a 3-bolt flange.\n*   A custom delete tune is required for your L5P to prevent the ECU from searching for the missing Diesel Particulate Filter (DPF) and DEF systems, which could otherwise lead to error codes or limp mode.\n*   For tuning, HP Tuners with CCS Tuning and an unlocked ECM are recommended.\n*   This system is not compatible with a 2021 GMC crew cab 4WD. It is, however, compatible with a 2020 crew cab and all bed and cab configurations for the 2017-2019 L5P models.","brand":"Flo Pro","offers":[{"title":"Default Title","offer_id":52688379445560,"sku":"680NM","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664198914.jpg?v=1784889351","url":"https:\/\/store.motormia.co\/products\/5-inch-downpipe-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
