{"product_id":"b58-downpipe-upgrade-2","title":"B58 Downpipe Upgrade","description":"The VRSF B58 Downpipe Upgrade is engineered to enhance the performance of 2019-2023 BMW M340i, M440i, M240i, X5 40i, and X7 40i models (G20, G22, G26, G05, G07 chassis). It is available in both race and high-flow catted configurations, featuring a 200-cell count for optimal exhaust flow.\n\nBy eliminating the restrictive factory catalytic converter, this downpipe reduces back pressure, resulting in quicker turbo spool, noticeable power gains (estimated 25-30hp with a tune), and a more aggressive exhaust sound. The construction utilizes a full 4.5\" diameter, hand-crafted and tig-welded SS304 grade stainless steel tubing with a CNC-machined 304 stainless steel flange for a smooth transition from the turbo to the mid-pipes. Smooth radius bends are incorporated to minimize turbulence and further increase flow.\n\nThe VRSF B58 Downpipe Upgrade comes with a lifetime warranty on the downpipe itself. However, please note that the warranty on the catted downpipe is limited to two years.","brand":"Mercury","offers":[{"title":"Default Title","offer_id":52687500280120,"sku":"10202010","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661670707.jpg?v=1784884828","url":"https:\/\/store.motormia.co\/products\/b58-downpipe-upgrade-2","provider":"MOTORMIA","version":"1.0","type":"link"}
