I had the same problem, first I had glass packs under the cab, Now I have the glass packs AND magnaflows AFTER the rearend, now it is too quiet. I'm pretty sure if you move the mufflers way far back it will be better, but since I have TWO sets of mufflers I don't know for sure. I'm half tempted to have the kid across the street take out the front set and see how it sounds. (he does the best work I have had done on the truck and is real cheap) But I am pretty sure having them WAY back will be better.
