{"product_id":"4-5-b58-downpipe-upgrade","title":"4.5\" B58 Downpipe Upgrade","description":"The VRSF B58 Downpipe Upgrade is a performance exhaust component crafted to replace the restrictive factory catalytic converter, leading to faster turbo spool, increased power, and a more aggressive exhaust note. This downpipe is offered in both a catless race version and a high-flow 200-cell catted configuration. It is constructed from hand-crafted, tig-welded 4.5\" 304-grade stainless steel, ensuring durability and corrosion resistance. The CNC-machined 304-grade stainless steel flange provides a smooth, seamless transition from the turbocharger to the mid-pipes.\n\nIt is compatible with both the stock cat-back exhaust system and aftermarket cat-back systems. VRSF offers a lifetime warranty on this product, with the exception of the catted downpipe, which carries a two-year limited warranty. The available gains are an estimated 25-30hp when paired with a tune.\n\nThis downpipe is specifically designed to fit the following BMW models equipped with the B58 engine: 2019-2023 G20, G22 \u0026amp; G26 M340i \u0026amp; M440i xDrive; 2019-2022 F22 M240i \u0026amp; xDrive; 2021-2023 G42 M240i \u0026amp; xDrive; 2019-2023 G05 X5 40i \u0026amp; xDrive; and 2019-2023 G29 Z4 M40i.","brand":"VRSF 4.5\"","offers":[{"title":"Default Title","offer_id":52664102846776,"sku":"10202010","price":281.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687538453.jpg?v=1784333271","url":"https:\/\/store.motormia.co\/products\/4-5-b58-downpipe-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
