Exhaust gas gives up energy (in the form of heat) just travelling down a pipe, and quite a lot more on its trip through a muffler. That's why it was common to see new cars and trucks with, for example, 2-1/2" pipe before a muffler, and 2-1/4" after.
So, yes, bends would be best after mufflers, but the power difference is probably close to immeasurable.
