{"product_id":"304-stainless-steel-front-pipe-j-pipe-w-high-flow-cat","title":"304 Stainless Steel Front Pipe\/J Pipe w\/ High-Flow Cat","description":"The Invidia Front Pipe\/J Pipe is a performance exhaust upgrade specifically engineered for the 2015-2021 Subaru WRX with a manual transmission. It directly replaces the most restrictive part of the factory exhaust system, the down-pipe, utilizing a larger diameter and smoother bends to allow the turbocharger to expel exhaust gases more freely.\n\nConstructed from premium 304 stainless steel piping with a 1.5mm thickness and featuring laser-cut cast steel flanges, this J-pipe is built for high-temperature resistance and long-lasting, leak-free reliability. It incorporates a 300 CPSI high-flow catalytic converter, which helps maintain emissions compliance for street driving while minimally impeding exhaust flow. The design ensures a 100% bolt-on installation, with provisions for factory O2 sensor locations for seamless integration with existing systems.\n\nInstallation includes a cat-back gasket and necessary nuts\/bolts, though the turbo to down-pipe gasket is sold separately. It is important to note that this upgrade requires tuning to function optimally and achieve advertised performance benefits. The product is backed by Invidia Exhausts Australia's limited lifetime warranty on structural welds, mufflers, and internals, with specific warranty periods for catalytic converters and other components.","brand":"Invitia","offers":[{"title":"Default Title","offer_id":52688899998008,"sku":"INV-HS15SWMDOCB","price":1273.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662671446.webp?v=1784898417","url":"https:\/\/store.motormia.co\/products\/304-stainless-steel-front-pipe-j-pipe-w-high-flow-cat","provider":"MOTORMIA","version":"1.0","type":"link"}
