{"product_id":"sport-series-catted-downpipe-for-b58","title":"Sport Series Catted Downpipe for B58","description":"The Evolution Racewerks Sport Series 4.5\" High Flow Catted Downpipe is engineered to enhance performance for BMW's B58 six-cylinder turbo engines. This downpipe replaces the restrictive factory catalytic converter with a high-flow 200-cell metallic unit, designed to significantly increase horsepower and torque while improving throttle response and reducing turbo lag.\n\nConstructed from 100% stainless steel and TIG welded, this downpipe features a precision CNC machined 4.5\" V-band flange that seamlessly integrates with the turbocharger outlet, eliminating turbulence and backpressure. The piping is mandrel bent to ensure smooth exhaust gas flow. It is compatible with both factory and aftermarket exhaust systems and includes all necessary hardware for installation. The product also features a durable flex section, mirroring BMW's design to prevent stress on exhaust components and the turbocharger.\n\nThis downpipe is explicitly not for sale, installation, or use on licensed vehicles in the state of California. It is available for international customers without restriction. A Vehicle Compliance Waiver must be signed for use in the 49 states excluding California.","brand":"Evolution Racewerks","offers":[{"title":"Default Title","offer_id":52687978856760,"sku":"BM-EXH015CAT-B","price":945.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664708411.webp?v=1784888443","url":"https:\/\/store.motormia.co\/products\/sport-series-catted-downpipe-for-b58","provider":"MOTORMIA","version":"1.0","type":"link"}
