{"product_id":"n20-catted-downpipe","title":"N20 Catted Downpipe","description":"The Active Autowerke Catted Downpipe is engineered to enhance the performance of BMW's N20 engine found in F-Chassis models like the 228i, 328i, and 428i. It replaces the restrictive OEM downpipe with a 3.5-inch diameter, TIG-welded 304 stainless steel pipe to significantly reduce exhaust back pressure. This design allows for faster turbo spool, improved horsepower and torque, and a more responsive engine.\n\nThe downpipe incorporates a 4-inch GESI G-Sport High Output catalytic converter. This converter is EPA registered, OBD2 compliant (in 49 states), and utilizes proprietary precious metal loading technology to greatly reduce emissions, minimizing the likelihood of triggering a \"Check Engine Light.\" It is rated for engines producing 500-850 horsepower and can withstand temperatures up to 1500°F, while its high-flow design ensures minimal restriction.\n\nThe downpipe is constructed from durable 304 stainless steel with 1.5MM wall thickness for longevity. Active Autowerke covers this downpipe with a 5 Year \/ 50,000 Mile warranty on the shell and tube ends, and a 2-year \/ 25,000-mile warranty on the catalytic core.\n\n**Important Fitment Note:** This downpipe is specifically designed for vehicles with the N20 engine. It will NOT fit vehicles equipped with the N26 engine. Please verify your engine type and include your VIN when ordering. Additionally, the catalytic converter is not legal for use in California due to state regulations.","brand":"Active Autowerke","offers":[{"title":"Default Title","offer_id":52686763000120,"sku":"11-079","price":1424.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661162930.webp?v=1784876447","url":"https:\/\/store.motormia.co\/products\/n20-catted-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
