{"product_id":"304-stainless-steel-ceramic-coated-downpipe","title":"304 Stainless Steel Ceramic-Coated Downpipe","description":"The VRSF 3.5\" downpipe upgrade is crafted from hand-tig welded, mandrel-bent 304-grade stainless steel and features a CFD-optimized cast merge collector for a smooth turbo-to-mid-pipe transition. This ceramic-coated downpipe replaces the restrictive factory catalytic converter, significantly reducing back pressure. This modification leads to faster turbo spool, increased power, and a more aggressive exhaust note.\n\nThe ceramic coating helps manage exhaust heat, decreasing intake air temperatures and engine coolant\/transmission oil temps.\n\nPlease note that this is a race-use-only system and will not pass MOT emissions testing. Installing this downpipe may trigger error messages in the cockpit due to altered lambda values, requiring reprogramming to resolve. It is intended for off-road use and is a significant performance upgrade for BMW N55 turbo engines.\n\nThis downpipe fits the following BMW models: 2011-2013 E82 135i N55, 2010-2013 E90\/E91\/E92\/E93 335i \u0026amp; 335xi N55, and 2012-2015 E84 X1 35i N55.","brand":"BMW","offers":[{"title":"Default Title","offer_id":52662769910072,"sku":"10902015","price":289.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687496362.webp?v=1784320765","url":"https:\/\/store.motormia.co\/products\/304-stainless-steel-ceramic-coated-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
