Catalytic converter options

[goldNSX]

Being 8 years old the cats failed the SMOG test due to high CO at 2500 rpm. They're 300 cells (Prospeed style but a different brand) with a perfect fit for 600 bucks back then. Car has a CTSC system.
What are the options nowadays? They should keep up with the CTSC but also guarranty SMOG for some years (the more expensive - the more years of course).
I've seen the ones from SoS, SARD and KSP.

There's also Pride. Probably one of the cheapest of the options. I haven't heard many reviews on them though.

Did you try posting on FB? I got the PRIDE High Flow Cats, but didn't install yet. I got some responses to questions on FB about the PRIDE Cats.

Thanks for the FB hint. I'm not on FB but found this: http://pridegroupinc.com/prideexhaust/product/acura-nsx-hfc
Unfortunately, they say they 'might not pass smog in some states'.

Now, I recall the brand of the old cats: Random Technology 300 cells.
