I wouldnt. Flow is more restricted in the cat, therefore the sensor reading will be jacked up....

Mine is about 2 inches past the midshaft... but I dont have a cat. I wouldnt mount it too close before the cat. Gas stream slows down in that area due to restriction caused by the cat. At least mount it before it passes the firewall. That is the best area to allow for wiring route anyway.....
