{"product_id":"5-inch-muffler-catback-exhaust-system","title":"5-Inch Muffler Catback Exhaust System","description":"The Nameless Performance catback exhaust is a high-performance system engineered specifically for the 2015-2021 Subaru WRX and 2015-2018 STI. It utilizes a 3-inch resonated main circuit paired with 2-inch dual rear circuits to manage exhaust gas flow efficiently. This design focuses on maintaining midrange torque while reducing cabin drone during cruising, providing an aggressive sound profile only when at wide-open throttle.\n\nCrafted from 100% T304 stainless steel, the system includes hand TIG-welded joints, v-band clamp assemblies, and high-temperature ceramic wool muffler packing for long-term durability. The setup includes 3-inch double-wall polished tips with a 10-degree angle cut, arranged in a staggered configuration to complement the vehicle's rear valence. All necessary hardware and OEM Subaru gaskets are included to ensure a proper fit.\n\nThe installation process utilizes a conical flare joint with a floating flange and a proprietary 3-inch donut gasket, allowing the exhaust to connect to either a factory downpipe or an aftermarket equivalent with factory-like compliance. This system is designed as a direct-fit component for the specified Subaru models using the EJ series engine; it is not compatible with other vehicle configurations not listed.","brand":"Nameless","offers":[{"title":"Default Title","offer_id":52663080812856,"sku":"SUCB15WRX-5MU-30SDW","price":1547.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687514574.jpg?v=1784323614","url":"https:\/\/store.motormia.co\/products\/5-inch-muffler-catback-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
