{"product_id":"3-catted-downpipe-j-pipe-with-gesi-gen-2-converter","title":"3\" Catted Downpipe\/J-Pipe with GESI Gen 2 Converter","description":"The STM Catted Downpipe\/J-Pipe is a performance upgrade designed for the 2022+ Subaru WRX. This component serves as the connection between the turbo and the cat-back exhaust, offering significant improvements in exhaust flow and power output. The unit is hand-fabricated using Tig-welded, back-purged techniques and constructed entirely from stainless steel for durability and corrosion resistance.\n\nKey features of this downpipe include a 400 CPSI GESI Gen 2 G-Sport UHO EPA Converter, ensuring emissions compliance while maintaining high flow. It utilizes 3\" 2-bolt exhaust flanges and is equipped with two O2 bungs to accommodate front and rear oxygen sensors. The design allows it to bolt directly to the stock turbo and cat-back exhaust, with compatibility for stock-placement cat-back systems. This downpipe is rated to support up to 850 horsepower, promising a faster spool and increased power across the entire RPM range.\n\nInstallation of the STM Catted Downpipe\/J-Pipe includes new 2-bolt gaskets and hardware. For optimal performance and potential CEL (Check Engine Light) mitigation, it's recommended to consult with a professional regarding tuning, especially given the inclusion of two O2 bungs which support factory sensor placement.\n\nThe STM downpipe offers a substantial weight savings compared to the stock unit, with the factory downpipe weighing 24.7 lbs and the STM unit weighing 16.2 lbs, resulting in an 8.5-pound reduction. This not only contributes to performance but also ensures a fully stainless exhaust system that resists rust and enhances the vehicle's sound. STM backs this product with their Standard Limited Lifetime Warranty.","brand":"MAPerformance","offers":[{"title":"Default Title","offer_id":52662933094712,"sku":"STM-VBWRX-DP","price":1249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687502647.jpg?v=1784321891","url":"https:\/\/store.motormia.co\/products\/3-catted-downpipe-j-pipe-with-gesi-gen-2-converter","provider":"MOTORMIA","version":"1.0","type":"link"}
