    What adds up to your Mazda Miata's efficiency is its ever-reliable emissions system, which cradles the catalytic converter. The Mazda Miata's catalytic converter is responsible for breaking down hazardous compounds such as nitrogen oxide, carbon monoxide, and hydrocarbons into non-toxic gases. These gases go through oxidation and reduction as they enter the catalytic converter. So when they are released from your car, they won't be causing too much pollution in the environment. So make sure that your catalytic converter is properly maintained because once it malfunctions, it does not only bring about problems in your car's fuel efficiency and engine performance but in your surroundings as well.

    Frequently Asked Questions

    Ask APW
    • How is a high-flow Mazda Miata catalytic converter different from a regular converter?
      Answer: A high-flow catalytic converter has a wider diameter, which allows for a better exhaust flow than the ordinary cat con. And when there is less restriction in the exhaust flow, an increase in the engine's horsepower can be expected. The torque is also boosted, although not in very high levels. So basically both high-flow and regular converters function to clean the exhaust fumes; it's just that the high flow provides a better flow for the exhaust.
    • What causes a Mazda Miata catalytic converter to fail?
      Answer: A catalytic converter usually malfunctions as a result of another problem--much like a domino effect. When it gets clogged, it's not only because unburned fuel is trapped inside the converter. Something else is causing that problem, and it could be due to an uncontrolled fuel delivery by an improperly tuned engine. One should not only look at the immediate causes of a catalytic converter failure. Address the root causes because if not, the same problems will only come up repeatedly no matter how many times the converter is replaced. Another common problem with the Mazda Miata catalytic converter is corrosion. While it seems normal for some car parts to rust away, leaks can cause a converter to become contaminated. Oil and fuel that seep into the converter can seriously damage it. What causes these leaks may root from something outside the converter.
    • What happens when the catalytic converter is removed from Mazda Miata?
      Answer: Note that if the catalytic converter is removed, chances of failing in the emissions test are high. And its removal is actually illegal. Nevertheless, removing the cat con can lead to improvements in horsepower and fuel efficiency. The exhaust gases are released faster and at higher levels, so the backpressure is reduced. Lower backpressure means less strain on the engine, enabling it to operate more efficiently.
