1996-97 OBD II cat
This ceramic core is OBD II compliant, for the 1996-1997 miata with secondary O2 sensor (it will fit the 1994-1997 cars). We designed this cat because of a need for an affordable replacement for the very expensive Mazda cat, and one that would not trigger the check engine light which is a common problem for the aftermarket cats designed for 1.8L cars. This catalytic converter replaces your restrictive and worn-out cat with this high flow cat to reduce backpressure, improve throttle response, and restore performance. Hardware and gaskets included.
