The downside to the wraps is that they tend to hold moisture and rust out headers pretty fast.

i've always thought with wrapped headers you sprayed them with some kind of header paint after they're wrapped and it seals out the moisture.  at least for a time - maybe that degrades and they do contribute to rusting.  i never had a chance to try it with the borla manifold on my subaru but that seemed how everyone with those cars did it.
