{"product_id":"sports-series-4-5-catted-downpipe","title":"Sports Series 4.5\" Catted Downpipe","description":"The Evolution Racewerks Sports Series 4.5\" High Flow Catted Downpipe is engineered to significantly reduce exhaust flow restrictions in BMW B58 six-cylinder engines, leading to increased horsepower and torque. It replaces the factory catalytic converter, a major bottleneck, with a high-flow 200-cell metallic core that allows exhaust gases to pass more easily, resulting in improved throttle response and faster turbo spool-up times.\n\nConstructed from 100% 304-grade stainless steel, this downpipe features mandrel-bent 4.5\"\/4\" piping for a smooth transition to the exhaust system. It is 100% TIG welded for superior quality and durability. The precision CNC machined turbocharger V-Band flange ensures a seamless connection to the turbocharger outlet, preventing turbulence and backpressure that can hinder performance. Options include a brush finish, polished finish, and a high-temperature black thermal coating to reduce underhood temperatures.\n\nIt also offers optional bungs for wideband O2 sensors and EGT gauges.\n\nIMPORTANT RESTRICTIONS: This item is not for sale, installation, or use on licensed vehicles in the state of California. It is for sale for international customers without restriction. A Vehicle Compliance Waiver must be signed for use verification in the 49 states excluding California. This product is intended for off-road competition use only.","brand":"Evolution","offers":[{"title":"Default Title","offer_id":52687976104248,"sku":"BM-EXH018","price":850.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687898586.jpg?v=1784888387","url":"https:\/\/store.motormia.co\/products\/sports-series-4-5-catted-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
