cat problem
the passenger side cat on my 98 z28 has developed a very loud rattle, when i pound on the cat i can hear something inside the cat move around, has anyone experienced this problem and if so what was the remedy? looking at the system it appears that i am going to have to remove the entire system to cut out the old cat, if i do not replace the cat and just weld in a piece of tube, will i have any trouble codes

i got a letter from GM the other day saying that they would replace the LH and RH cats from the dealer for free if there was a problem with them. it was for 2002 5.7's only.
