Every vehicle I've ever installed headers on has been louder, even on the few where I've made no other exhaust system changes. Sometimes only a little louder, but I've also noticed a smoother tone over stock cast iron manifolds.

It's normal for you to hear more sound from outside the headers themselves. The thinwall tubing used on headers just seems to allow more sound through rather than absorbing it like the heavy cast iron does. Thus, we get the typical header "ticking" sound (not the exhaust leak ticking) which most people seem to like. Some don't, however. I have a buddy who hates it and won't run headers on any of his trucks. Stock cast iron only, through Flowmasters and duals.

Get under the truck while it's running and listen for leaks, feel around for leaks...
Headers will make it louder, as TigerDan said the headers are just thin tubing and are not thick cast iron so sound does change.
I wouldn't be overly concerned as long as there are not any leaks.

Are they misaligned?
Loose?
Shouldn't be too hard to fix...
My y-pipe didn't line up with my headers very well, so I took a torch and heated up the y-pipe and bent it in line with the headers and it sealed up well.
