Low temps on the outside of exhaust pipes is no reason for concern. I know the gas coming out of the block is hotter, and I still have a few square feet for Fiberfrax blanket laying around. Though I don't have enough to rap header to tail pipe, it isn't that hard to come by if you know what your looking for.
