{"product_id":"s58-high-flow-catted-downpipes","title":"S58 High-Flow Catted Downpipes","description":"The VRSF S58 High Flow Catted Downpipes are engineered for the 2019-2024 BMW X3 M and X4 M (F97 \u0026amp; F98) models equipped with the S58 engine.\n\nThese downpipes offer a significant performance upgrade by replacing the restrictive factory catalytic converter with a high-flow, 200-cell catalytic converter. This modification substantially reduces back pressure, resulting in faster turbo spool, a noticeable increase in horsepower and torque, and a more aggressive exhaust note. Direct bolt-on installation can yield gains of 30 whp and 35 wtq, with potential for up to 60 whp and 100 wtq when paired with a DME remap.\n\nConstructed from hand-crafted, mandrel-bent, tig-welded 304-grade stainless steel tubing, these downpipes feature smooth radius bends designed to minimize turbulence and maximize flow. The CAD\/CAM optimized CNC flanges are also made from 304-grade stainless steel.\n\nThis item specifically fits the following BMW vehicles: 2019 – 2024 F97 BMW X3M S58 and 2019 – 2024 F98 BMW X4M S58.","brand":"VRSF","offers":[{"title":"Default Title","offer_id":52866546303288,"sku":"10972011","price":562.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687406082.jpg?v=1787909260","url":"https:\/\/store.motormia.co\/products\/s58-high-flow-catted-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
