New mufflers, not too loud wanted

I am looking for a couple mufflers for my Dart Sport with a 360-350 HP, 9 to 1 comp. The mufflers I have now are way too hard on the ears at highway speeds and the drone is terrible.
I have 22'' x 8'' of room to work with. Looking for a sound like the newish 1/2 ton trucks, low rumble at idle and nice sound at higher speeds. Lets try to keep it under $60.00 per muffler.
HELP PLEASE
