i need new mufflers for a 81 chevy. someone help me please

I am replacing the mufflers on my '81 chevy k20 pickup that has a 350 crate with headers. Could someone give me some ideas? I go 4-wheelin alot and id like it sound real good so.any ideas are welcome

On our 86 K10 plow truck with blackjack full length headers we got a kit from summit racing with dual 2 1/2 pipe, h-pipe and cherry bomb welded(looks like copy of flowmaster) muffs and alot of the gearheads around here like the sound. I like the system because it goes out behind the back tires and is all tucked up so it doesn't get caught. Hope that helps.
