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.

Huge improvement

Got this last week and its a huge improvement over the 26 year old stock unit, not much louder but sounds noticeably better. Would absolutely buy again.

Still fine

Bought 11 years ago when I bought the catback FM exhaust. No issues, would buy again.

Overpriced, get the magnaflow bolt in.

The entry and exit pipe is only slightly larger than the bolt in magnaflow which is $100 less. The internals appear to be exactly the same and allow the same amount of light to pass through, and thus the same amount of gases... the magnaflow isn't even considered a highflow btw.

Note: Any smaller cat will significantly increase your exhaust volume.

Excellent CAT

Failed emissions in my boosted 96 Miata. Purchased this CAT which was easy to install and flows good. I then passed emissions in flying colors!

Bought Two Years Ago, No Complaints!

Bought it to replace the stock one and to save some money, and I ended up getting a deeper, more throaty sound (which I love!) and it bolted right up with absolutely no issue. Usual trouble-free experience with FM, and would recommend this product to anyone who needs a cat (or cheap exhaust upgrade!)
