I'll keep you all informed and am appreciative for the assist.

If you look at the illustration I posted you'll see the part number "7335794" this is repeated 4 times across the pic and right next to it is an illustration of an exhaust clamp as well as the #3 indicating a 3 inch diameter exhaust clamp for the 3" exhaust system from the factory. I had to replace the intermediate pipe, muffler & tail pipe on mine back in June with these parts as mine was all rusted to hell as well. Still running the O.E.M. CAT/ Convertor though but will be replacing it next summer with a smaller sized high flow 3" in/out model.
