{"product_id":"3-5-ss304-cat-back-downpipe","title":"3.5\" SS304 Cat-Back Downpipe","description":"The VRSF 3.5\" Stainless Steel Downpipe is a performance upgrade for the N55 engine, specifically designed for the 2011-2017 BMW X3 xDrive35i (F25) and 2014-2018 BMW X4 xDrive35i (F26) equipped with a Pneumatic Wastegate (PWG).\n\nThis direct bolt-on downpipe is constructed from hand-crafted, tig-welded SS304 grade stainless steel, featuring smooth radius bends to minimize turbulence and maximize flow. By eliminating the restrictive factory catalytic converter, it significantly reduces back pressure. This results in faster turbo spool, a noticeable increase in horsepower and torque, and a more aggressive exhaust note.\n\nAvailable in either a track-limited (catless) or a high-flow catted version (featuring a 200-cell catalytic converter), this downpipe offers a substantial performance improvement. Gains of 20-25hp are achievable with a tune. VRSF backs this product with a lifetime warranty on the downpipe itself. The catted version has a two-year warranty, and any optional ceramic coating (utilizing Cerakote High Temperature Ceramic Coating) comes with a one-year warranty.","brand":"VRSF","offers":[{"title":"Default Title","offer_id":52664232313144,"sku":"10252010","price":229.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687615011.jpg?v=1784335596","url":"https:\/\/store.motormia.co\/products\/3-5-ss304-cat-back-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
