{"product_id":"304-stainless-steel-unequal-length-cat-back-exhaust-system","title":"304 Stainless Steel Unequal Length Cat-Back Exhaust System","description":"This system replaces the stock header and up-pipe, which are known limitations in the factory design, offering a solution that increases horsepower, boosts torque, and sharpens throttle response while reducing turbo lag. The unequal length design also contributes to a more aggressive and desirable exhaust note.\n\nConstructed from premium 304 stainless steel, this header and up-pipe features smooth mandrel bends and an increased piping diameter to minimize exhaust restriction. The unequal length layout is a key design element for achieving the desired performance gains and sound characteristics. The package includes all necessary zinc-plated hardware and new exhaust gaskets for a complete installation. Its stainless steel construction ensures durability and resistance to corrosion.\n\nThis product is specifically designed for Subaru models, including the WRX from 2002-2014 and the STI from 2004 onwards. It is also compatible with other Subaru models such as the Legacy GT (2005-2009) and Forester XT (2004-2008). Installation hardware and new gaskets are included, simplifying the upgrade process.","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":52688780427576,"sku":"IAG-EXT-1000","price":849.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687905018.webp?v=1784895768","url":"https:\/\/store.motormia.co\/products\/304-stainless-steel-unequal-length-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
