You should not have lost power from such a simple bolt on, as long as you didn't damage anything such as the cats, o2 sensors. Your power loss may be due to another issue.
If indeed nothing was damaged and your power loss is coming from the new mufflers, then I'd say there's something inside the mufflers or pipes that are causing a blockage.
But I seriously doubt it. Good luck.
