RE: glasspack muffler
I have a glasspack on my blazer, it sounds good and everything, I like the crackle of it, but nothing like a chevelle with a small block. A v6 and a v8 have a huge difference in sound.

RE: glasspack muffler
i used to have a glasspack on my camaro... recently switched over to a magnaflow.
i think if given the choice i'd go back to the glasspack. the magnaflow sounds nice but the glasspack is quieter. i wouldnt shy away from the glasspack mufflers, IMHO they dont deteriorate any faster than anything else in the exhaust system unless youre going stainle$$.

RE: glasspack muffler
I just installed a cherry bomb glasspack on my blazer today. I like the crackle and poping sounds it makes, it has a good back flow note too. it was cheap, the muffler was $25ish and the brackets, piping, and everything else was about another $40. So far I love the sound, but then again it has only been a few hours. I was thinking about how long they last and I figured that if it goes in another 2 years, I can just go buy another one for $20, no big deal.

RE: glasspack muffler
wish i could help..but as youve said, a 5.7 liter is alot different than the 4.3..... i love the sound of my dual cherry bombs. A plus to glasspacks is that they dont blow apart at the seams..mainly cuz they dont have any.. 
i bought my truck with custom exhaust on it..dont know the brand of the muffler but i know they were tiny little turbo mufflers and my cherrybombs sound sooo much better, anyway, back to the blowing apart...a friend and i were going fishing,, and offroading a bit, and all of a sudden somethin started rattlin...scared me to hell cuz i had juss put a new tranny in the truck and i almost crapped my pants haha ahh i'm not bein any help am i ..ahah but glasspacks are a good, cheap form of exhaust.

I had glasspacks on my Chevelle thru true duals and will never go back to them. The reason being simply this, they wear out rather quickly. Yeah they are cheap and they flow very well, but their sound deadening material is basically fiberglass stuffed into the space between the outside barrel and the inside perforated tube. As the glass gets blown out the tail pipe, they gradually get louder and louder, crackling more as well.
Now it has been quite a few years since I have ever done anything muffler wise, but my Chevelle has Thrush Turbo mufflers on it now and they have a nice deep rumble to them. But I'll let others that have done exhaust more recently comment on what you should get to attain the tone you require.

That's what my stock blazer with a glass pack sounds like everything else is stock right now
