This is a *very* common belief:  that without a cat, the
van will run better and my mileage will be better.  This is
*not* what I was taught in a 2yr automotive program, and
they were very straight-forward with us, not just
politically correct.  (This does assume that the internal
honeycomb isn't busted apart and clogging the exhaust).

Use the cat - it is the right thing to do, even if it isn't
the law (and it usually is).  Furthermore, the entire
planet, and your children will thank you.

David
