Novice muffler install - advice needed Options

[pugface]

Hi guys

Often time when I am trying to do some work on my car, I find instructions that skip certain things because 'everybody knows' some steps. Unfortunately, I don't know all the little tips and tricks.

I just pulled off my exhaust - the car came with a a Bursch glasspack exhaust that makes a terrible sound. My car also came with a bunch of spares, I thought I'd try the stock muffler that came in the pile. Although there were no gaskets when I removed the old muffler, I assume there should be?

Also, occaasioanly I see reference to copper nuts, copper paste, anit-seize - are there extra things I should be doing besides just using a new gasket and a bolt from Ace hardware?

I would like to be able to get this muffler off in a year or so, so any tips are appreciated!

Thanks
