2001+ LS1's had the LS6 intake manifold over the LS1, for a little bit better air flow. Not too much of a performance difference, 10-15 horsepower maybe. GM rated it at 20 more but every LS1 engine performs differently from the next...Lots of information in the LS1 Based Engine Tech section in the stickied threads...I got all that info from the one about LS1 Specs and P/N's.
You can get gear information by looking at your RPO codes on the inside of your driver's side door jam. The automatic LS1's I believe came with either 3.23:1 or 2.73:1 ratios. 3.23's are code GU5 and 2.73's are GU2. If you have GU6 then they are 3.42's. My V6 had GU6 as the option, and I have never seen anyone else that had that (on a V6). meh. A GU4 code is 3.08 but that was only on V6 RS models I believe.
I don't know if there is much of a difference in exhaust between the different year stock F-bodies...Kiiiind of doubt it though. If you're asking about aftermarket there's a whole can of worms you can open about that through using the search bar. Everyone likes something different.
Injectors...they're usually at 28 lb/hr ratings, don't know if there is a variance from year to year. I've seen a couple posts about them being 26 lb/hr. If you're thinking of upgrading them there are lots of threads about what the best kinds/brands are as well. No need to upgrade injectors though unless you're doing serious modifications to the engine. I'm still using stock injectors even on a car that turns just under 500 crank hp. (though they are running about 95% duty cycle at WOT) If you use bigger than necessary injectors, it probably won't run perfect at varying throttle points.
