{"product_id":"racing-beat-exhaust-system","title":"Racing Beat Exhaust System","description":"The Racing Beat complete exhaust system is a high-performance upgrade designed for the 1983 Mazda RX-7, engineered to improve exhaust flow on stock-ported engines. The system includes a header\/collector, a stainless steel Power-Pulse presilencer, and a stainless steel Power Pulse main muffler.\n\nIt is important to note that this kit does not include the factory connecting pipe that mounts just ahead of the main muffler, as replacing that section provides no horsepower gains. The system is specifically tuned to provide a performance increase while maintaining a low, pleasant exhaust tone that is only slightly louder than the stock configuration.\n\nRegarding performance, this system offers a typical 22% increase in horsepower at 7000 rpm on stock-ported engines compared to the factory exhaust. Please note that this specific Racing Beat part number 16415 is distinct from other automotive components that may share the same numeric identifier.","brand":"SKF","offers":[{"title":"Default Title","offer_id":52663314448696,"sku":"16415","price":1239.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527221.jpg?v=1784325856","url":"https:\/\/store.motormia.co\/products\/racing-beat-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
