{"product_id":"catless-stainless-steel-downpipes","title":"Catless Stainless Steel Downpipes","description":"These Racing Dynamics Catless downpipes are engineered specifically for the BMW 535i Xi with Xdrive E60\/E61 models from 2007-2010, featuring the N54B30 motor. The straight-through design replaces the factory catalytic converters, significantly reducing back pressure to enhance turbo response, horsepower, and torque, with typical gains of 20-25 HP.\n\nEach pipe is equipped with two O2 sensor bungs, allowing for the transfer of your existing oxygen sensors to ensure normal ECU operation. This modification can lead to a \"Check Engine Light\" (CEL) being illuminated due to the removal of catalytic converters; a reprogrammed ECU or a CEL fix, such as a mini-cat, may be necessary. The reduced thermal load on the turbocharger and less turbo lag contribute to an improved driving experience.\n\nDesigned as a direct bolt-on replacement, these downpipes come complete with all necessary gaskets and bolts for installation. The specified fitment includes the BMW 535Xi with Xdrive E60 sedan (2007-2010) and the BMW 535Xi with Xdrive E61 Touring (2007-2010). Additionally, the fitment list includes the 2008-2010 BMW 535i, 2009-2010 BMW 535i xDrive, and the 2008 BMW 535xi.\n\nPlease note that these parts are intended for off-road or track use only and are not legal for use on public highways. This product is sold for off-road use exclusively and is not for sale or use in California.","brand":"Racing Dynamics","offers":[{"title":"Default Title","offer_id":52663415767352,"sku":"130 10 54 975","price":429.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687136240.webp?v=1784326725","url":"https:\/\/store.motormia.co\/products\/catless-stainless-steel-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
