Comes with a secondary O2 bung, which is the practical difference that makes it work on both OBD1 and OBD2 Miatas without weld-in fittings.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eCatback replacement for the 1.8L NA Miata. The 2.5\" piping flows substantially better than the choked factory exhaust, the brushed stainless construction holds up to weather and heat cycling, and the polished muffler with 4\" tip gives the NA a proper aftermarket sound without going obnoxiously loud. The pre-fitted secondary O2 bung handles OBD2 NA Miatas (which have a downstream O2 sensor) without requiring a fabricator.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e1994-1997 Mazda Miata NA (1.8L naturally aspirated) only.\u003c\/strong\u003e Tested on both OBD1 and OBD2 Miatas. \u003cstrong\u003eWill not fit Euro-market Miatas.\u003c\/strong\u003e Not designed for the earlier 1.6L Miata (1990-1993).\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x 2.5\" brushed stainless front pipe with precision flanges\u003c\/li\u003e\n\u003cli\u003e1x midsection\u003c\/li\u003e\n\u003cli\u003e1x tail section with polished stainless muffler and 4\" tip\u003c\/li\u003e\n\u003cli\u003eSecondary O2 bung (pre-fitted)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-CSEXH-NA\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Circuit Spec catback exhaust (two-piece)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e 1994-1997 Mazda Miata NA (1.8L naturally aspirated, US market)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eExcluded:\u003c\/strong\u003e Euro-market NA Miatas, 1.6L NA Miatas (1990-1993)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eOBD Compatibility:\u003c\/strong\u003e OBD1 and OBD2 (secondary O2 bung included)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brushed stainless steel piping, polished stainless muffler\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePiping:\u003c\/strong\u003e 2.5\" front pipe\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eTip:\u003c\/strong\u003e 4\"\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Complete kit\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957113053381,"sku":"IS-CSEXH-NA","price":605.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/ISR_1__92974.1740446451.500.659.jpg?v=1773346835","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-mazda-miata-na-circuit-spec-exhaust-1994-1997","provider":"ISR Competition","version":"1.0","type":"link"}
