{"product_id":"b58-downpipe","title":"B58 Downpipe","description":"The VRSF B58 Downpipe Upgrade offers a significant performance enhancement for your BMW's B58 engine. This downpipe replaces the restrictive factory catalytic converter, reducing back pressure and leading to faster turbo spool, increased power, and a more aggressive exhaust note. It is constructed from hand-crafted, tig-welded SS304 grade stainless steel, featuring a full 4.5\" diameter and a CNC-machined flange for optimal flow.\n\nAvailable in either a catless version or with a high-flow 200-cell catalytic converter, this downpipe is designed to fit seamlessly with both stock and aftermarket cat-back exhaust systems. Its smooth radius bends further contribute to decreased turbulence and increased flow efficiency. The product fits both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) models without requiring any modifications.\n\nInstallation of this downpipe is compatible with the following BMW models: 2016+ F22\/F23 M240i \u0026amp; M240i xDrive, 2016+ F30\/F31 340i \u0026amp; 340i xDrive, 2016+ F32\/F33\/F36 440i \u0026amp; 440i xDrive, 2016+ G30 540i \u0026amp; 540i xDrive, and 2016+ G11\/G12 740i \u0026amp; 740i xDrive. VRSF provides a lifetime warranty for the race (catless) versions and a one-year warranty for the high-flow catted versions. A tune is recommended to achieve the stated performance gains of 25-30hp.","brand":"BMW Works","offers":[{"title":"Default Title","offer_id":52687193801016,"sku":"10582010","price":215.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661664210.webp?v=1784881260","url":"https:\/\/store.motormia.co\/products\/b58-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
