{"product_id":"b58-catted-downpipe","title":"B58 Catted Downpipe","description":"The Active Autowerke Supra MKV Catted Downpipe is engineered for the B58 engine, aiming to significantly reduce the exhaust back pressure that restricts the OEM downpipe. By utilizing 4.5-inch diameter 304 stainless steel piping, it facilitates quicker turbo spool and increased power output. The piping tapers down to 3.5 inches and includes a stainless flex joint, ensuring compatibility with the OEM exhaust system while never dropping below 80mm in diameter.\n\nThis downpipe features a 4.5-inch GESI G-Sport Ultra High Output Catalytic Converter. This EPA-registered converter is OBD2 compliant for 1996 and newer vehicles and is designed to prevent Check Engine Lights (CELs) in 49 states. It is rated for engines producing 500-850 horsepower and can withstand temperatures up to 1500°F, reaching operational efficiency within 9 seconds of startup. The converter's 400 cells per square inch provide ultra-high flow with reduced emissions, meeting EPA standards but not CARB standards. It is explicitly noted that these catalytic converters are not legal for use in California.\n\nA key benefit of this downpipe is that NO PERFORMANCE TUNE IS NEEDED, simplifying the upgrade process. The downpipe is constructed from TIG-welded 304 stainless steel for durability and includes a cast upper stainless steel V-band for precise fitment. It is made in Miami, Florida, and comes 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. Note that the warranty is void if the vehicle has excessive burble beyond stock, as this can damage the catalytic core.","brand":"Active","offers":[{"title":"Default Title","offer_id":52686761492792,"sku":"AA-SUPRA-DP","price":1499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178849.webp?v=1784876426","url":"https:\/\/store.motormia.co\/products\/b58-catted-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
