Primary cat

[jgtfour]

Anyone got an extra primary cat from a 92 st185 they don’t need anymore or for sale? I have a gutted one on right now because it got all clogged up full of crap last year. This will be the first time I’m going to smog it with this thing on. Hopefully it passes but if not, it’ll be nice to have an extra one in case I don’t.

I'm sure there are many differences between CA and TN but the sniffer part can't be that different. . that said, mine passes well under the HC limit of 220 and I have no emissions on the engine (JDM) and no cats (I'm surprised it passes the visual, they might confuse the resonator as a cat).
