gutted cat for dinner

[Rave Racer]

        My Kitty is coming apart at the flange making big noise.  I think
that the O2 sensor is reading the exaust gas wrong because it's mixing with
something else and this is affecting my mixture.  I don't know yet as this
problem is relatively low on my "Broken Car Stuff" list.
