{"product_id":"wrx-rev-4-catted-downpipe","title":"WRX Rev 4 Catted Downpipe","description":"The MAP Performance WRX Catted Downpipe Rev 4 is engineered to significantly improve exhaust flow leaving the turbo for your 2015-2021 Subaru WRX MT. By replacing the restrictive factory downpipe, this component allows spent exhaust gases a quicker exit, which can lead to increased horsepower and torque across the entire power band. The Rev 4 features a 3.5\" bell mouth that tapers to a 3\" diameter, optimizing flow and reducing restrictions.\n\nIt utilizes mandrel-bent tubing throughout to ensure smooth exhaust gas velocity. A stainless steel flex section is incorporated to mitigate stress caused by engine movement, thereby increasing the longevity of the exhaust system. The design also incorporates a 304 stainless steel CNC turbo outlet flange and utilizes the OEM turbo outlet gasket and ground strap.\n\nThis downpipe is 100% Made in the USA. Please note that this product will not fit CVT models. Customers should select the appropriate option via the dropdown menu before ordering, especially if using a stock cat-back, as an optional Grimmspeed flange adapter may be required.","brand":"MAP Performance","offers":[{"title":"Default Title","offer_id":52662894625080,"sku":"WRX-4G-DPC-REV4","price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687502654.jpg?v=1784321788","url":"https:\/\/store.motormia.co\/products\/wrx-rev-4-catted-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
