The good news, at least for many of us, is that the OEM cat is not a restriction at or near stock power level. Dave also mentions this, and I've re-confirmed from another source that the factory unit actually flows quite well and should last a very long time. I think the only problem is when you need a 2 1/2" or 3" exhaust for more serious power mods.

Glad you passed! This topic seems to come down to just the luck of the draw as far as passing visual. As Dave mentions above, there are zero CARB-legal aftermarket cats.

Apathy Kills
Run an ARB search by manufacturer under the category "NON OBDII CATALYTIC CONVERTER". You will see that the standards are somewhat more relaxed compared to the OBDII catalytic converters. For CarSound, the ARB listing basically says "Consult the manufacturer's catalog."

just to add another voice of reason to this....my brother passed the sniffer and visual of his smog with a jdm itr 4-1 with heatshields, 2.5'' carsound cat and exhaust.
it varies widely depending on the shop you take it too. some are more stringent than others.
