Cherry Bomb Sound Question?

Im looking at buying a Performance Muffler for my 99' Monte Carlo. Cherry Bombs are right in my price range but I had a few questions about them. What type of sound will they produce? Will it be like those people who try to sup up civics and sound like little rice burners, or will it be a nice, fairly deep sound. Also what is the difference between a free flow and a gl pack in terms of sound. I am not so much looking for performance so much as the sound. I would like a nice deep tone and was wondering if cherry bomb made a muffler for my needs.
