340 exhaust help

I know this has probably been gone over a million times, and I must have read 100 different threads but I haven't quite gotten a direct answer.

I have just bought my first real muscle V8. It's a 340. Right at the moment it has turndowns coming off the headers with no baffling, and it's just too dang loud for the street. Being my first high strung V8, and I'm a young gun (22), I want a real ground pounder. I want to set off car alarms and shake windows. I live out in the country so neighbors aren't a big problem. However, I don't want to be deaf by 30, or drive around with ear muffs on. I really love that drag car sound, and I don't want to sound exactly like every other mustang and V8 on the preverbial block. I was thinking of going with a glasspack of some sort, like a set of purple hornies turn towns, but also know these are vey loud. I have to recarpet the car anyway, so if I go nuts with dynomat and sound deadener, can I seal the cab well enough that is isn't a giant reverberation chamber and bareable?

The car isn't a DD, it's a weekend and friday night toy. The occasional trip to work, but mostly just a toy.
