Need exhaust help please....1986 K2500

[VTKidder]

I have an '86 3/4 ton 4WD plow truck that needs exhaust. The exhaust rotted off at the manifolds, so I replaced both manifolds, and am ready to put some exhaust back on the truck. Both manifolds come down at a 45* angle at the back of the manifold. I wanted to just have a "downspout" that bolts to the manifold, then a small muffler, then a 90* elbow out the side of the truck somewhere under the back of the cab. This truck is just to plow my road and help a few neighbors, so it won't be legal; I'd just like quiet enough to not wake up the world when I'm plowing!

Does anyone have pics of what I need, or even better, some part numbers or anything? I'm looking to do this on the cheap. I can weld up anything I need to as well. Thanks all.
