{"product_id":"r1-spec-3-inch-cat-back-exhaust-system","title":"R1-Spec 3-Inch Cat-Back Exhaust System","description":"The Remark R1-Spec cat-back exhaust system is engineered for performance enthusiasts, specifically for the track-ready Subaru WRX\/STI VA chassis (2015-2021). This system is designed to maximize performance gains by reducing exhaust gas back pressure through its large 3-inch diameter piping and high-flow, straight-through muffler canister. The aggressive tone is suited for track use while remaining manageable for daily driving, with customer reviews noting minimal drone at highway speeds.\n\nConstructed with a T304 stainless steel midpipe, the muffler and tip are available in either durable T304 stainless steel or lightweight titanium. The system includes a large 4.5-inch slant-cut tip with a laser-engraved Remark logo, enhancing the vehicle's performance aesthetic.\n\nInstallation requires the removal of the factory donut gasket. Remark does not recommend the use of aftermarket adapters, as they may cause incorrect fitments. For 2019-2021 WRX\/STI VA models, compatibility is confirmed. The stainless steel muffler version weighs 23.6 lbs, while the titanium version weighs 20.3 lbs.","brand":"Remark","offers":[{"title":"Default Title","offer_id":52872033698104,"sku":"RK-C1076S","price":995.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/r1-spec-3-inch-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
