Check out Flowmaster, Inc The Muffler and Exhaust Technology Company manufacturer of performance exhaust systems, mufflers, exhaust kits and look up their 70 series muffler. From what I can tell, it should be almost stock-quiet on your truck, and apparently you won't sacrifice any performance at all.
I'm thinking of trying one of those 50s for my '97, since it also has a 40, and is pretty loud.
40s are one of their more quiet mufflers. 44s and 10s are ridiculous loud compared to 40s.
