Joseph,
This actually happens more often than people think. Take your truck back to
the people that welded your aftermarket exhaust on. I assume the
aftermarket exhaust went from the cat back. They need to re-weld the cat to
the muffler. Sometimes this depends on the type of metal of the aftermarket
muffler as well. My cat-back system is a Borla system. It is stainless
steel from the cat all the way back. The people that installed it for me
made sure it was welded all the way back as well. Besides Borla
guaranteeing it for life so did the muffler shop that did the welds. If you
look underneath my truck it looks like a solid piece from the exhaust
manifold to the phantom tailpipe.

Jon,
The crack is just slight I can't see through it it is right next to where
the pipe exits the cat. I am going to look closely at a friend's 99, on
monday. I have driven her's and I hear no exhaust noise what so ever. I
think i will try the baby power to see if there is a leak.
Also another thing I forgot to mention. When I was investagating I tried to
shake the exhaust, between the headers and the Cat, I was able to move it
about 1/3 of an inch in both directions. When I shook it I also notice that
the Tranny and drive shaft moved as well. Any thoughts?
Thanks for the help
Joe

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!
