Depending on the year model, you could go with a flowmaster 40 series or something like that. On the newer models, probably like 2000 and up, that are not too too loud, but sound pretty decent. Yea, cherrybomb glasspacks are cheaper, but they are loud and to me, don't sound all that appealing. Maybe even a dynomax or thrush turbo muffler would sound ok on your truck without being too loud.
