so my slight exhaust rattle has matured into a full on cacophonous symphony that is ever so annoying and I'm wondering what the best method is for dampening, adjusting, realigning... etc?

sounds like you have an old rusted system, unless you have a welding torch and what not, it is best to just take it to a muffler place and have them replace it, they are one of those things that just goes and cant be fixed just has to be replaced.

check the rubber hangers before going off to get a new exhust. But maybe you will some welding and what not?????

Catalyic converter shield coming loose? They make a racket when the mounts start to rust away...

well I should add that I recently removed the whole exhaust before replacing my shift linkage bushings... it was rattling before that but only slightly... and the catalytic converter shield was pretty bad so I just removed it... there is, however some kind of a heat shield above that muffler that's pretty rusty and loose... but that isn't the soul source of the sound...

so did I not reinstall in properly or should I be looking to replace this thing and if so, what would you estimate I'm looking at?

if im looking at the right thing on dcauto.com it looks like it will cost around 70$ for the new heat shield and, if you replace it in and around 100 for the new tail pipe. you may also need mounts which should be in the 40$ range. bad mounts have been on my list of things to repair for a long time, some of them look like pieces one can get from home depot or your local hard ware store.
