I have a 98 4x2 v8 5spd 3.55sg, do not have the HD service group, and
about 2500 miles on it. I get some snap crackle pop whenever I
decelerate as you described above. It is especially noticeable if I'm in
one of the lower gears (3rd or lower). I've not noticed any serious
backfiring though (I assume you meant exhaust backfires), just medium
loud rumbling and poping. I'm sure this will get louder when I install
an aftermarket exhaust.
Are these the noises you are describing, or do get real bang-bang type
backfiring - the kind that sounds like its going to blow the muffler
off? My Dak's rumbles and pops are nowhere near that bad.

TSBs can be found on the Alldata and NHTSA web sites.
