{"product_id":"4-stainless-steel-cat-back-exhaust","title":"4 Stainless Steel Cat-Back Exhaust","description":"The RoadsterSport 4 Stainless Steel Exhaust system is engineered as a direct-fit, cat-back upgrade for the 1990-1997 Mazda MX-5 Miata (NA chassis). This exhaust system is constructed from durable T-304 polished stainless steel, including the hangers, ensuring longevity and a premium appearance.\n\nPerformance and sound are enhanced through a combination of a standard resonator in the connecting pipe, which minimizes rasp, and an exclusive Helmholtz chamber in the main rear chamber. This advanced design significantly reduces interior \"boominess\" and \"booming\" frequencies in the 120-130Hz range by over 40db within the Miata cabin, even with the top down. For further sound customization, the system includes removable baffles, allowing you to fine-tune the exhaust note to your preference.\n\nInstallation is facilitated by the included mounting hardware and gasket. The system is backed by a lifetime manufacturer warranty, reflecting the quality and durability of the materials and construction.","brand":"RoadsterSport","offers":[{"title":"Default Title","offer_id":52663518003512,"sku":"910-347","price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687613746.jpg?v=1784327640","url":"https:\/\/store.motormia.co\/products\/4-stainless-steel-cat-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
