{"product_id":"high-performance-exhaust-valves","title":"High-Performance Exhaust Valves","description":"The MMR Severe Duty Exhaust Valves (520600) are engineered for extreme performance, capable of handling up to 11,000+ rpm and 4000hp. These valves are an ideal choice for naturally aspirated road race vehicles and turbocharged Pro Mod applications, ensuring reliability where factory components may fail.\n\nDesigned as a direct \"plug and play\" upgrade, these valves fit specifically into 5.2 GT350 and 2020+ GT500 cylinder heads. They feature a factory valve size with an undercut for improved flow compared to stock valves, contributing to increased power output. The valves also include a single bead lock retainer groove and come with 16 bead locks included for a secure installation.\n\nIt is important to note that while these valves are designed for the 5.2L GT350 and 2020+ GT500, they are specifically an upgrade for the exhaust side. Other 5.0 Ford Coyote engines (Gen 1-4) utilize different valve part numbers, and these severe duty exhaust valves are explicitly stated to *not* fit GT350 cylinder heads that are not the 5.2L variant.","brand":"Modular Motorsports Racing (MMR)","offers":[{"title":"Default Title","offer_id":52689280074040,"sku":"520600","price":2011.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687392762.jpg?v=1784904556","url":"https:\/\/store.motormia.co\/products\/high-performance-exhaust-valves","provider":"MOTORMIA","version":"1.0","type":"link"}
