With a defective or clogged cat you can actually feel the decrease in performance and notice a decrease in fuel economy. Trapped exhaust gas creates back-pressure which prevents your engine to breathe properly. This may cause your engine to quit after a few minutes of driving or make the engine feel like it is starving for fuel.

Due to a number of complaints of the short life-span of cheap aftermarket versions, and recent increased requests begging for the availability of stock OEM Genuine Mazda Miata Catalytic Converters we have put them on the site, here you go!

Note: A common cause for catalytic converter failure is a defective oxygen sensor. When you replace your cat, we highly recommend getting a new oxygen sensor with a brand that states it has an OE, Original Equipment, type connector.
