'89 YJ, 4.2L.....Recommended Exhaust??

[strmh]

Two questions about my recently purchased '89 YJ......

I've got an exhaust leak around the manifold which I plan to fix.....

1-Is the removal of the exhaust manifold fairly straight forward, or are there some tricks I should know about?

2-What are some recommendations for exhaust systems?? I'd like something that has a good sound, but not too obnoxious.
