I had a customer call me who is living in California.  He needs to replace
the exhaust system on his 2.0l air cooled Vanagon in order to get the van
through inspection (smog).  We have the parts for the federal air cooled
exhaust system (which includes a cat and egr valve but no place for an
oxygen sensor) and many of the parts for the California system are NLA.  I
thought maybe the guy could put the federal setup on his van and then just
cut a hole in one of the pipes to put in an oxygen sensor.  He wonders if
this will fly with the smog referees.  Anyone know how strict they are?  Do
they actually check your system against a diagram of how it should be, or do
they just check to see if all of the components are there (cat, oxygen
sensor egr valve)?

Any advice would be appreciated.

Thanks,
