Hello,
I am concerned that the front catalyst on my 83 XJ6 could
have failed or might be in the process of failing. I haven’t
looked down it yet, but with over 98000 miles on the car,
the odds seem in my favor. This may seem strange, but is it
possible to break the insides up sufficiently to hollow it
out without actually removing it from the car, or will I
need to figure out how to do that too? I know this is an
environmentally irresponsible thing to do, and the fact that
my area doesn’t test for smog doesn’t absolve me. But I’m
probably going to do it anyway, and will replace the cat in
time.
Thanks,–

FWIW the front catalytic converter on my 83 xj6 had been opened up (by the
PO?) as evidenced by the fact that a 4" x 6" section had been cut out, then
welded back in place—presumably to “gut” the insides of the CC. I don’t
think you are going to be able to break up the insides without removing
it—or without cutting it open.
I had to replace both my catalytic converters in order to pass local
emissions inspection.

Mileage has nothing to do with how long a convertor lasts. They
are designed to last the life of the car. Unless there is physical
damage, something coming loose inside, or a meltdown from an
improperly running engine, the convertor should still be good.
That being said, be careful hoolowing out a convertor. If the
element is removed, youy may end p with ringing sound when the
engine is running. This can be corrected by welding a tupe in the
convertor.–

William, I heard that the cat in a particular '79 XJ6L was
removed from the car, one of the pipes was marked for proper
re-alignment, cut off, the cat was secured in a vice and
using a large screwdriver and hammer the insides were broken
apart and removed, then it was taken to an exhaust shop
where they welded it back together. I seem to recall that I
also heard that there is a mesh type material lining the
inside of the cat and when enough material is removed the
mesh can be peeled away from the inside wall of the cat and
then the inside is clean enought to eat off of! Well…
Just something I heard once!–
