Product Questions & Answers

Q:Is this Catalyst meets Colorado Standards ?
Ariel P.
A:BEST ANSWERHi Ariel, thanks for initiating contact. No, it does not. Colorado's catalytic converter regulations now align closely with CARB standards, requiring compliance for aftermarket converters and ensuring that vehicles maintain emissions performance. I suggest calling our parts specialists at 1-866-529-0412 to provide the vehicle information so we can help you look for the right part. Have a good one. Show less

Customer Guides

How is a high-flow Mazda Miata catalytic converter different from a regular converter?

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?

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?

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.

P0430 Code: Catalyst System Efficiency Below Threshold  (Bank 2)
P0430 Code: Catalyst System Efficiency Below Threshold (Bank 2)A failing catalytic converter breaks down less pollutants in the exhaust, resulting in lower oxygen (O2) levels overall. The downstream oxygen sensor detects the change and informs the vehicle’s computer. In turn, the computer activates the check engine light and logs the appropriate OBD-II trouble code for diagnosis by a
