{"product_id":"rs-race-cat-back-exhaust-system-80mm","title":"RS-Race Cat-Back Exhaust System 80mm","description":"The GReddy RS-Race exhaust system is engineered for the 2015-2021 Subaru WRX\/STI sedan, specifically for the VA1 and VA2 chassis equipped with either the EJ257 or FA20T engine. This full stainless-steel cat-back system features a large 80mm (3.14-inch) diameter, non-tapered piping for maximum flow. The aggressive-looking system includes a 115mm (4.5-inch) tip and is designed for applications where reduced sound suppression and enhanced exhaust flow are priorities.\n\nIt is designed as a direct replacement for the factory cat-back section and includes an 80mm oval gasket along with a specialized composite gasket (part number 11000329) to replace the stock \"donut\" gasket. The system retains the factory catalytic converter and front pipe, contributing to a surprisingly mild sound level during cruising, with a notable rumble under wide-open throttle.\n\nFor further customization, the RS-Race features a tri-bolt tip that allows for the installation of optional RS Tip Silencers (51mm or 43mm) and various tip lengths and styles, including genuine Titanium with a burnt finish. Despite its cost-effective price point, GReddy ensures that quality materials, construction, and craftsmanship are maintained. The stock system weighs 39 lbs, with the weight of the RS-Race TBA.","brand":"Greddy","offers":[{"title":"Default Title","offer_id":52688601284920,"sku":"GRE10168408","price":570.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663690814.webp?v=1784891689","url":"https:\/\/store.motormia.co\/products\/rs-race-cat-back-exhaust-system-80mm","provider":"MOTORMIA","version":"1.0","type":"link"}
