Cat Question

[GMAN]

Is there a difference between Gen1 93-95(ODB1) cats, 96-98 (ODB2) Cats?

I'm gonna say no

I dont think so, I thought it was common to swap exhausts between Gen1 and Gen2.

the OBDII Marks have 4 oxygen sensors; one before each cat and one after each cat. I think the OBDI Marks only have an oxygen sensor before each cat. I've never looked on an OBDI Mark to confirm...
