Default dealer replacing cat. converter

My dealer is replacing the Cat Converter on my car Monday. Rattled until it came apart and clogged exhaust. Anyone know the procedure? Do they replace all four or just the bad one...??

Keep us posted on what they change (just the bad cat, whole pipe section with cats etc) and cost. I Have an 02 Coupe as well and think one of my cats is bad. Getting Rattle on accel and Decel and intermittent P0430 codes.

I have 97000 on mine tho so no more warranty on them.

I'd like to know if they are replacing the intermediate pipe with both cats, or installing an aftermarket cat. What is the current mileage on the car?

I have 37000 miles, year 2002. I'll post the results of my repair after Monday. By the way, per Chevrolet, the cats are under warranty for 80,000 miles or 8 years.

the cats and h-pipe assy is one piece, if warranty is paying you'll get two new cats and h-pipes as an assy.
