I can't believe it, my CAT split in 2!!!!
I was driving my 2000 ML320 on 101 then all of a sudden, the car started to make this HUGE horrific sound... sounded like a riced out Civic with a coffe can exhaust...
I thought it was prob my exhaust gasket, so I took the car in for service....
When they jacked the car up, I could not believe it... The cat on the driver side, split opened, very clean, looks like laser cut.. the weld looks ok, but it just split opened... Could not believe it... Dealer wanted to charge me $800+ to fix it... I took it to a muffler shop and welded that thing back!
I just could not believe it would split open like that...

All to common. Below are the links to my little experience with the same problem.

Happens all the time. Rewelding may not last either. Generally by the time they are that old and crack in two, the cats will start to rattle or clog up.
Its expensive to fix because the exhaust pieces are very expensive, and we also have to remove the torsion bars to get the cats out. That means we have to reset the ride hieght when its all reassembled. Its not a difficult job, just involves more work than doing cats on most other cars.
