{"product_id":"power-pulse-exhaust-system","title":"Power-Pulse Exhaust System","description":"The Racing Beat 16415 is a complete, high-performance exhaust system specifically engineered for the 1983 Mazda RX-7. This system is comprised of Racing Beat's Header\/Collector, a Power-Pulse Presilencer crafted from stainless steel, and the signature stainless steel Power Pulse main muffler.\n\nDesigned for ease of installation, all components in the 16415 system are intended to attach to the factory mounting points. The package includes all required gaskets and hardware. The only part not supplied is the factory connecting pipe located just ahead of the main muffler, as replacing it with a larger diameter assembly offers no horsepower advantage.\n\nA typical gain of 22% at 7000 rpm can be expected, though the exact increase varies depending on the stock RX-7 exhaust system being compared against. The combination of the Power-Pulse Presilencer and Power Pulse Main muffler results in an exhaust note that is only slightly louder than stock, characterized by a pleasant, low tone.","brand":"Racing Beat","offers":[{"title":"Default Title","offer_id":52663411704120,"sku":"16415","price":1239.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687134181.jpg?v=1784326692","url":"https:\/\/store.motormia.co\/products\/power-pulse-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
