I had a 1994 chevy K1500 with the 5.7 350 small block. I loved the truck in every way, but the exhaust was just too quiet for me. I had a muffler shop install a flowmaster single in/dual out to the bumper. Sounded great, like a whole different truck. There wasn't much drone at all. I got rear ended and the exhaust got all bent up, so I had to get the two pipes past the muffler replaced. I put them at an angle past the rear tire, sort of at a 45 degree angle, and had larger tips installed. Then, the truck sounded AWESOME. It had a very deep tone, I used to love driving that truck with the windows down.
