I have been hearing a rattling noise from inside my exaust does that mean the cat is shot or could it be my glasspacks coming apart?

Have you tried to tap on the exhaust while the pipes are cold to see if you can get a rattle anywhere?
It shouldnt be too hard to spot from under the truck. I a good muffler shop would also be able to tell you.

I think the 98-99 cats are on recall check the TSB's.

My truck nis a '95.The cat is less than 4mo. old and the glasspack is less than one year old.I guess I sould take it back to the shop to complain.

could it possibly be a mount? maybe one of the welds came loose? just a thought

 

[joe blow]

just had a broken mount fixed a couple of weeks ago.

My stock diesel exhaust rattles, only because I put a dent in the muffler the size of a grapefruit. Have you checked for any dents in it or places where it's been hit?

I haven't had this problem with my Dodge but my Ranger has some sort of heat sheild on that has collected rocks a time or two. You may want to check for that.

That was my next guess. check the shield around the cat.
