the main cat under the car is enough to meet the tailpipe emissions. in Ca we have a visual check, so the downpipe fails that part.

Most smog techs wont notice a missing precat. Likely it will pass.

^ +1. In all the years we've had our '94, it has never failed visual here in Southern California.

I have my downpipe wrapped and they don't even notice. However I am failing miserably for some reason.
