Max,
Both the A/C compressor and the exhaust manifolds are attached to the engine block, so they should both move togther when the engine rocks. The reason I chose the powerlog is because I knew I could intall it and the downpipe myself. I would have to pay someone to install headers making them more expensive. The "lot more performance" is debatable for those who don't plan on doing much more modifications. If I felt comfortable doing the headers myself, I definately would have gone that route.
