Snowman,
I essentially the same thing on both of my trucks (93 C3500, 94 K1500). On both trucks, I had a 3" high flow converter, 3" flowmaster muffler, with single 3" pipe all the way out the back. Both of them have a very nice sound, and a drastic improvement in gas mileage. Both trucks have the 350. My 3500 can get 10 mpg now, where before I was at 4. (I carry 14000 pounds in it daily) My 1500 went from 16 to 20. Not to mention the power improvement.
