Realized that both of my mufflers are going and whole exhaust system from cat back will need to be replaced this Spring, I'm looking forward to doing this myself, but I've got some questions:

-Is it a good idea to replace the 11-year old cat anyway? It passed emissions last year, but it's very rusty, and it looks like I can get a replacement one from FCP Groton for only $125. If I do the whole system from the end of the front pipe back, it should be much easier, right? (Just unbolt cat and take system down, hang new system and bolt in new cat, no worries about having to remove then re-attach rusty old cat to new system).

-Anyone know what type of bolts are used from end of front pipe to cat, and do I need a gasket in there - according to some parts lists, a gasket is required for cars with EGR, and I don't have EGR - but it seems like there should be, because this is a different fitting from the rest of the system. There are no bolts listed on any parts lists, but my old ones are really rusted, I'll need to replace them.

Thanks a bunch!
