NA8 Flyin’ Miata catalytic converter

Free flowing for better performance yet $300 less than stock! This converter is somewhat louder than an OEM converter and it`s perfect for Miatas with turbochargers! The same stainless steel flanges used on our exhausts are also used on the cats. 5 yr/50,000 mile limited warranty on the body and flanges, 25,000 mile warranty on the converter internals (its ability to pass an emissions test). Comes with gaskets and bolts.

Works with all exhausts that follow the stock flange locations, orientations, and sizes – which is most but not all. The cat is a 300-cell ceramic unit. 

As with all of our catalytic converters, this cat is emissions-certified. Specifically, it’s EPA-approved for this application. Please note that these are not CARB legal and we cannot ship them to California. They’re also not legal in states requiring CARB cats. That’s California, Colorado, and New York for 94 and 96+ cars (yes, it’s still legal for 95 cars in NY). 

UK cars with a 1996 P registration or later may require the use of a Flyin’ Miata or other aftermarket exhaust to use this catalytic converter. The factory cat on these cars is longer (475mm instead of 440mm) and the exhaust system is not compatible with our cat.
