exhaust should fit fine.

Break in depends on who you're asking. Some people say it doesn't matter some people say it does. And it's split pretty evenly up the middle so just go with whatever you think is best.

2) Both the intake and exhaust have no moving parts so there is obviously nothing to "break-in"

Of course some will say it doesn't matter....I trust the dude with 30yrs that told me not to take it over 4k for the first 2000 miles and also to not drive at a consent speed but to very my speeds.

As far as the after market parts go. It shouldn't matter unless it's something to do with the new engine. Hell I would just wait until 2000 then mod away. It'll come faster than you think. One weekend of driving around I was able to put almost 600miles on her.
