Catalytic Converter Shootout
#2
Interesting, it seems to basically only affect CO and idle HC.
Thinking back, I think my old honda didn't actually have a working cat. Its hydrocarbons only dropped to something semi-normal around 1100 rpms. I got through smog in CA by fiddling with my idle to find a window where the RPM and HC were both barely legal.
