{"product_id":"b58-4-5-inch-downpipe","title":"B58 4.5-Inch Downpipe","description":"Introducing the VRSF B58 Downpipe Upgrade, engineered to be the most significant performance modification for your compatible BMW.\n\nThis downpipe is meticulously crafted from hand-tig-welded 4.5\" 304-grade stainless steel, featuring a CNC-machined 304-grade stainless steel flange for a seamless connection from the turbocharger to the mid-pipes. Available in both a race configuration and with a high-flow 200-cell catalytic converter, it significantly reduces back pressure compared to the restrictive factory unit. This leads to faster turbo spool, a notable increase in power, and a more aggressive exhaust note.\n\nThe design incorporates smooth radius bends to minimize turbulence and maximize flow. It is compatible with both the stock cat-back exhaust system and all aftermarket cat-back exhausts. The downpipe fits both Right-Hand Drive (RHD) and Left-Hand Drive (LHD) models without requiring any modifications for installation. VRSF offers a lifetime warranty on all stainless steel downpipes against defects and fitment, though the warranty for the catted downpipe is limited to two years.\n\nThis downpipe is designed to fit the following BMW models: 2019-2023 G20, G22 \u0026amp; G26 B58 BMW M340i \u0026amp; M440i \u0026amp; xDrive; 2019-2022 F22 B58 BMW M240i \u0026amp; xDrive; 2021-2023 G42 B58 BMW M240i \u0026amp; xDrive; 2019-2023 G05 B58 BMW X5 40i \u0026amp; xDrive; and 2019-2023 G29 B58 BMW Z4 M40i.","brand":"VRSF","offers":[{"title":"Default Title","offer_id":52664101896504,"sku":"10202011","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687538455.webp?v=1784333262","url":"https:\/\/store.motormia.co\/products\/b58-4-5-inch-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
