catalytic converter
 

Seeking the newsgroup wisdom on the following:

1997 Jeep Cherokee Sport (XJ, 4 liter, straight 6, manual tranny)
112K miles

A baffle inside the catalytic converter has come loose making for quite a
rattle when shutting off the engine.

I'd like recommendations for an after market, freer flowing catalytic
converter, cheaper would be nice too.

TIA - Jon

Re: catalytic converter
 

The 'baffle you with BS' noise is normally just the heat shield on the
outside with a broken foot. You can either bend the offending foot out
of the way or weld it back in place.

The shops have been telling me for 7 or 8 years now that our Cherokee's
cat is bad because it had that noise when they hit it. BS, it still
passes emissions with flying colors.

If it is actually dead, then I am sure someone here can chime in with
the best replacement.

My son left his 97 at our house because he now lives on the west coast. Be
fore he left he told me that he had a bad rattle. It was not the heat
shield but the cat had self destructed inside. His 97 was not on the recall
list for the cat but it was on the recall list for an OBC replacement. I
replaced his exhaust and the cat had totally melted down.

Re: catalytic converter
 

Mine coming apart clogged enough to notice were I was usually doing
55 MPH up hill away from stop lights at a 45 speed limit sign, I found
that was all I was doing.
