{"product_id":"b58-catted-downpipe-2","title":"B58 Catted Downpipe","description":"The Active Autowerke Supra MKV (B58) Catted Downpipe is engineered to significantly enhance the performance of your Toyota Supra. It addresses the restrictive nature of the factory downpipe, utilizing a 4.5-inch diameter 304 stainless steel piping construction to facilitate maximum power output and quicker turbo spool. This design minimizes exhaust back pressure, allowing the turbocharger to operate more efficiently and deliver increased horsepower and torque.\n\nA key feature of this downpipe is the integration of a high-flow GESI G-Sport Ultra High Output Catalytic Converter. This converter is EPA registered and fully OBD2 compliant, designed to reduce emissions and prevent Check Engine Lights (CELs) in 49 states. It is rated for engines producing 500 to 850 horsepower and maintains a high flow capacity, ensuring performance is not compromised. The catalytic converter is constructed from 304 stainless steel, including the substrate, and features proprietary precious metal loading technology for reduced emissions.\n\nThe downpipe maintains a diameter of 80mm where it meets the OEM exhaust system, ensuring it does not drop below the stock diameter. The product includes a turbo flange gasket, with Active Autowerke pre-installing it to prevent damage during customer installation.\n\nThis downpipe is specifically designed for the Toyota Supra MKV (A90\/A91) with the B58 engine, compatible with 2020 and 2021 models. Importantly, no performance tune is needed for installation and operation, although the provided dyno chart shows significant gains with the stock tune. However, it is critical to note that these catalytic converters are not legal for use on vehicles registered in California.","brand":"Active","offers":[{"title":"Default Title","offer_id":52686763393336,"sku":"AA-SUPRA-DP-C","price":1499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661162937.webp?v=1784876452","url":"https:\/\/store.motormia.co\/products\/b58-catted-downpipe-2","provider":"MOTORMIA","version":"1.0","type":"link"}
