Once installed, the car will have a standard CA smog sniffer test performed and recorded, so we can show exactly how low the CO2, O2, HC (PPM), and CO actually measure with these cats installed.

I took a look at these and the honey-comb inside looks sufficient, if these don't keep the CEL off and keep the car legitimately clean, I don't know what will!

Any news??
