After reviewing the Honda S2000 forums, I was actually looking to source a specific brand and part number to replace the rear CV Axle. Was surprised to discover the Autozone Duralast Gold was the exact brand/part number I was trying to source - just relabeled. The CV buckets are CNC machined and the axle aligned up perfectly and bolted right in. The first one worked so well, I replaced the other side too. The S2K is now smoother and the noise is gone.
