{"product_id":"circuit-spec-cat-back-exhaust","title":"Circuit Spec Cat-Back Exhaust","description":"The ISR Performance Circuit Spec Exhaust is specifically engineered for the 1994-1997 Mazda Miata NA models equipped with the 1.8-liter engine. This system is constructed from durable, brushed stainless steel for the 2.5-inch piping and flanges, ensuring longevity and resistance to corrosion. The muffler is also crafted from polished stainless steel and features a substantial 4-inch tip for a distinct aesthetic.\n\nDesigned with performance in mind, the Circuit Spec Exhaust is optimized for track and competition use, delivering an aggressive exhaust note. Its construction aims to improve exhaust flow, potentially enhancing engine performance. The use of stainless steel throughout the system not only adds to its durability but also contributes to its premium appearance.\n\nThis exhaust system is noted to be loud and produces a very deep bass note, which can be felt as rumbling and pressure waves within the cabin. Due to its aggressive nature and sound profile, it is designated as legal only for use in competition.","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":52872133345592,"sku":"ISR-MIA-NA-CS","price":613.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/circuit-spec-cat-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
