{"product_id":"x-pipe-front-catalytic-converter","title":"X-Pipe Front Catalytic Converter","description":"The Supersprint 788602 is a performance-oriented metallic catalytic converter system featuring an X-pipe design, intended to replace the OEM front catalytic converters. Crafted from durable T304 stainless steel in Germany, this component is equipped with high-flow metallic catalytic converters from HJS Motorsport.\n\nBy replacing the stock front catalysts, this Supersprint system significantly lowers exhaust backpressure and flow restrictions. This leads to improved engine performance. Simultaneously, the advanced HJS Motorsport catalytic converters, rich in noble metals, ensure optimal reduction of pollutant gases, allowing for periodic emission tests to be passed.\n\nFor vehicles where catalytic converters are integrated into the manifold, this system is recommended for use with Supersprint headers. The headers replace the OEM manifold with a freer-flowing, long-tube design. The metallic cats contribute to reduced pollutant output. While periodic emission tests should be passable, extending sensor wires and plugging the sensor after the new sports cats can help prevent Check Engine Light issues. It is important to note that this unit must be fitted with the Supersprint center section, as the outlets do not align with the OEM part. Alternatively, minor welding of a short pipe section can be performed for adaptation.\n\nThis catalytic converter system is compatible with Alpina B3 \/ B3 S (E46) 3.3ix 4x4 models from 1999 to 2005, BMW E46 320xi (2.2i) 4x4, and BMW E83 X3 M54 3.0L. A threaded bung for an oxygen sensor is provided.","brand":"Supersprint","offers":[{"title":"Default Title","offer_id":52663918068024,"sku":"788602","price":3380.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720252.jpg?v=1784330821","url":"https:\/\/store.motormia.co\/products\/x-pipe-front-catalytic-converter","provider":"MOTORMIA","version":"1.0","type":"link"}
