I have had some problems with the Cat (as anybody on the forum recently should know) and I'm thinking I'm going to need a new exhaust as some of the honeycomb from the ol cat might be in ther causing problems. My question is , from the cat back, what all needs to get replaced. I am new to this and I think theres the resonator, pipe and muffler. Is there a thread anywhere on how to replace the exhaust or atleast take it off the inspect it? I was thinking about buying what I need and trying it on my own as it seems fairly simple. Thanks in advance.

If you don't know how/have a place to weld the system up, I would say just take it to an exhaust shop. Prices vary from area to area, but probably 300-400 bucks will buy you a new single (dual if you're lucky) exhaust, installed.
Cat-back, of course, not including the cat I suspect you still need.
If you can weld and want to take a crack at it, it's as easy as buying the components and duplicating what is already on the car. There is an image on here of a complete LS exhaust system... I think it is in the knowledge database.
