{"product_id":"long-system-5-0l-v8-cat-back-exhaust","title":"Long System 5.0L V8 Cat-Back Exhaust","description":"The American Racing Headers Long System is engineered for the Lexus RC F 5.0L V8, model years 2015-2025. Constructed entirely from USA-sourced 304 stainless steel, this system features 1-7\/8\" primary tubes and 3\/8\" thick laser-cut flanges for a warp-free seal. Its hand-ported TIG welded inlets and optimized primary tube routing contribute to superior fit and performance, while merge collectors with scavenger spikes enhance exhaust flow.\n\nThis \"With Cats\" version includes severe duty 300-cell (or optional 400-cell G-Sport) catalytic converters, offering a deep, throaty tone without high-pitch rasp. It is designed as a direct bolt-in system that can be paired with stock or aftermarket axle-back exhausts. ARH also offers a \"resonator delete\" option for a louder sound.\n\nIt is crucial to note that ALL American Racing Headers exhaust systems are exclusively manufactured for racing purposes. This product is intended ONLY for closed-course competition use and is NOT legal for use on highway or street vehicles, or other non-racing competition off-road vehicles. Installation may be illegal nationwide under the Federal Clean Air Act. Purchasing this product requires signing a Vehicle Compliance Waiver. An optional upgrade to G-Sport catalytic converters is available for ARH Standard Catted Systems.","brand":"American Racing Headers","offers":[{"title":"Default Title","offer_id":52686916583736,"sku":"LRCF-15178300DFSNC","price":3999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660182334.jpg?v=1784878384","url":"https:\/\/store.motormia.co\/products\/long-system-5-0l-v8-cat-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
