No, that doesn't sound normal to me. Is there actually an opening, and
you can see right into the pipe? A loud exhaust is usually indicative of
a leak somewhere. What you may want to do is to let the engine idle, and
starting from the exhaust manifolds, and going back to the muffler, check
for leaks. (You may be able to feel them with your hand, or some people
sprinkle baby powder around the area for a visual confirmation. If you
have a leak anywhere in front of the muffler, that is probably the reason
for the loud exhaust. You may also want to get under the truck and listen
to where the exhaust is the loudest. (A stethoscope might help, but if its
as loud as you say you may not need one. Or you could get a friend to rev
the engine a bit.)
If you can't find the problem yourself, you may want to go to the
dealership and listen to a few other trucks exactly like yours. (Same
engine and bodystyle.) If they are quieter, insist that the dealer find
and fix the problem; if they can't, start to go up the corporate ladder and
complain to anybody who will listen.) :-)
Good luck!
