Type of Muffler

[armygrouse]

I'm not entirely ready for this phase in my project, but I'm just interested what everyone would suggest. I've got a '77 International Harvester Scout II tera, that I'm going to put a Chevy 350 motor in. I'm not sure if I'd rather get a muffler with one entrance and one exit, a duel muffler, or 2 mufflers with one entrance one exit each. Either way I'd like to have a resonator before it, and make it as quiet as possible without restricting flow.

thanks for any opinions
