{"product_id":"fabspeed-sport-catalytic-converter-downpipe","title":"Fabspeed Sport Catalytic Converter Downpipe","description":"The Fabspeed Sport Catalytic Converter Downpipe is a direct bolt-on replacement for the factory catalytic converter designed for BMW B58N-equipped models. It features German-made HJS 200-cell EURO 6 compliant trimetallic catalytic converters and utilizes 4-inch piping from the engine to the cat, transitioning to 3-inch tubing afterward.\n\nThis downpipe is constructed from CNC mandrel-bent T304L stainless steel and is engineered to allow for increased exhaust flow and better exhaust gas filtering, ensuring emissions compliance without triggering a check engine light. It supports over 1200 horsepower and offers significant performance gains across the RPM band, with further potential improvements achievable with an ECU tune.","brand":"Fabspeed","offers":[{"title":"Default Title","offer_id":53708960268600,"sku":"FS.BMW.B58N.SC","price":2784.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/820301281.webp?v=1793532789","url":"https:\/\/store.motormia.co\/products\/fabspeed-sport-catalytic-converter-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
