So I'm driving down the road going about 20 mph and I hear this loud bang in the back of the truck (I have nothing in the bed) over my loud rock music. At first I was afraid the pumpkin exploded, but the truck was still driving fine except now I heard something dragging...pulled into a parking lot and lo and behold it was one side of my dual exhaust from the muffler back. It rusted immediately after the Flowmaster muffler where it takes a bend to get over the axle just on one side. Looking it over, the other side is fine! Going from the headers to the muffler, everything looks great on the outside. From the muffler to the back tips, it looks rusted. Had a local shop reweld it back on, but damn! I'm not sure how old the exhaust is, I bought her 2 years ago with this system on it already and the truck's an '04. Anyone else have this problem?
