I may be needing a new cat right about now (gonna go to a shop who will let me know for sure). Been considering replacing the stocker with a CARB legal high flow unit. Anybody have opinions/wisdom in this area? Also, OEM is $500 while all the other ones are ~$200, not exactly sure why (less precious metal?).
Speak to me, Oppo.

Pick up a little power while not shelling out $500 for an OEM part, always seemed like the way to go to me. Just make sure to scrap the old one and don't just throw it away, OEM cats are worth a few bucks to scrappers.

Do you live in California? If not, fuck CARB. Go with whatever is cheapest and will allow the best flow (plus pass any needed emissions testing)

It certainly sounds like a no-brainer on the surface, that's why I've been looking for any kind of downside. All I've gotten so far was one guy saying OE was 'higher quality'—too ambiguous for me. I think an aftermarket unit from an established company would be just fine anyway.

Might as well, since you need a new one anyway. If you're in California then the CARB sticker will definitely be useful, but otherwise I wouldn't worry about it too much.

More power = Moar better. Every time.
CARB cert helps and it's less money? No-brainier.

I run one of the track car. Helped to keep it a little more legal in Chicago, since if they ever did a visual check, the car still had a cat. Dunno. I was replacing the downpipe and catback no matter what, and it wasn't that much more to go with the high-flow cat over not running one.

Test pipe? Hollow out the stock cat?

I put a Magnaflow hi-flow CARB cat in my Miata after it failed smog. I couldn't feel a difference in performance, but it made a little more sound, crackled nicely on overruns, and passed smog with flying colors.
I used SellYourCatsDirect.com to scrap my old converter, and I think they gave me like $75 for it. Their website indicates that they are currently having regulatory issues, but I'd imagine there are other places that offer the same deal.

Oh, regarding the "OE is higher quality" because they have less precious metals, that's only true for non-CARB cats. IIRC CARB cats are required to have the same or better vs OEM. I have seen some CARB cats from cheapo brands with terrible-looking welds and bends, but if you go with a good brand name, I would expect to get something as good as or better than OE.

1.6? Mine passes smog as is so I can only imagine it would be no issue whatsoever if I went high flow. I was looking at Magnaflow, but read on an Amazon review (of all places) that this cat lost its CARB-legal status as of May this year. Not sure what to think.
Do you know of any other high quality CARB legal cats for Miatas (esp. 1.6)? Haven't found much more than Magnaflow at this point, and if that truly has been booted then I'm not sure what options I have.

"I may be needing a new cat right about now"
That's so sad. Is your old cat sick? Did it pass away?
I suggest you get this orange tabby cat as a replacement:

Meow. I'd like one of those cats as well. I'm gonna have lots of cats when I settle down.

Not my car, but I have test pipes (and a tune). The primary cat delete is supposed to net 20 horses and the tune is supposed to net ~20 more, so I should be sitting right around 450 at the crank now. Very happy with it.

Yeah, I bought the one that I'm pretty sure you're referencing from Amazon back in 2011 - one of the reviews is mine :).
According to what I can see on Magnaflow's site ( http://www.magnaflow.com/02catalytic_co… ), the part number for the currently CARB-certified cat has changed, the new part is 332684, which is also on Amazon but has Prime shipping :).

Random technologies is the leader in this field. they flowtest and know how long the elements need to be to function. Fit and finish is great. Disclaimer, Dave Emanuel is a friend and owner and his writing/books inspired me to work in the aftermarket

Okay, good to hear. I was at the shop today and tomorrow morning he's gonna call and give me a quote on ordering and installing a Magnaflow for me. If a California muffler shop is ordering a part, no doubt it's gonna be CARB legal.

Yup. And it may well be cheaper for them to order a generic fitment cat and weld it up themselves than it would be to buy the custom fitment cat.

So, update! The muffler man called, told me he could cut out the old cat between the flanges and weld in the Magnaflow high flow for $450 out the door. I said yes. Totally came to the realization the other day that there's nothing wrong with the cut-n-weld method. Gaskets might be a little old but if they work they work. I'm excited—little change in sound is more than welcome!

Very cool! Be sure and post up with your thoughts on the sound differences.
