Glasspack help.

[Rat96]

I have been doing some research and still having trouble. If I want loud, go with 12" cherry bomb glasspack. But if I want a deep throaty noise, go with a little bit longer glasspack. I know I keep having questions, but I need answers so I don't make a purchase and then regret it. I have factory ram horns, true dual exhaust, and 2.5" pipes. I just need to know the size (length) of cherry bomb glasspack I need for a really loud and deep throaty noise. Also where the best place to get them.

Thanks,
Wyatt
