that's what i had on my truck, and there really is nothing that can be done about it without spending more money. you could try dynomating the floor, or another choice of sound deadening. or you could spray bedliner on the underside of the body for the same effect, neither of these are going to be a real fix. the 40 series just drones a lot, it's in the design of the muffler. if you could cap one pipe that may help a little bit.
