Yikes!! Don't pay MSRP from the dealer on that stuff.
I run the Fullsac b head pipe and Rinehart 4" mufflers. I used to have the Fullsac baffles but wanted more sound, which I got with the Rineharts.
If I were you, I would first pick up the Rineharts from Eastern Performance of Direct Harley Parts, and you will pay around $430.00
Then, go for the Fullsac or Jackpot head pipe. I'd go Fullsac because while you're ordering from him, get the TTS tuner and Steve will provide you a map for free that you can easily download yourself, and will be spot on or at least close enough that you won't have to get a dyno tune.
Finally, do the work yourself or find a good Indy mechanic near you. If you don't know of a good Indy shop, ask around here.
I guarantee you will spend half of what the stealer is quoting you, and you will be happy with the results.
As far as cams, my personal opinion is wait until you rack up like 15-25 thousand miles before you do the cam. Reason being is that I see a lot that are not happy with their cam choices, as far as just a cam swap goes. If you were going to take the heads off to slip in a thinner gasket, then you may as well be at the point where the engine could use a re-hone/ring job, headwork, etc. I just don't think the cam is worth it on it's own unless you plan on doing the other preventative maintenance stuff while you're in there.
