I helped a friend apply a sound deadening called Lizard Skin to his '67 C10. This stuff is sprayed on and covers great. It's not the cheapest solution but I can tell you it works. His Truck has a 3 inch exhaust with 40 series Flowmaster Mufflers. The Truck is quite inside, you can have a normal conversation without shouting.
