downpipe - cracked?

In general, if one did crack, it could be the result of a bad weld, or excessive stress due to misalignment. Heat-shield wrapping could make it more susceptable to cracking due to the increased temperature in the metal.

It's possible, although it would be the first time I've heard of it.
The strength of a weld can vary widely based on how it was done, what weld wire was used, base material, voids, cracks, cleanliness, corrosion, etc, etc. No doubt, a cheap downpipe is more likely to have crap welds. In most cases, the downpipe carries very little stress, but with the right combination of things it could break them. I would take it up with the original vendor and send them photos of the break.
Most good vendors of welded products will usually step forward and supply a replacement. It seems in this case like it would be impossibly difficult to break a good weld. This case almost certainly hinges on a bad weld.
