For those that are wondering, that HP difference was on a FI car so it would be safe to assume that on a NA car the gains are almost negligible between metallic and ceramic.

I'm in SD, but I travel to LA every once a month. So, anywhere near the 5 or 405 freeways, up to SFV I can meet whomever.
The power gains are probably similar to a cat back exhaust. The cats are the most restrictive part of the exhaust systems on 350z/G35's. So, you'll definitely feel the difference.
You guys are putting too much emphasis on the cell count of the cat. There is negligible difference in HP between 400 cell and 300 cell if you are NA. If you are entry level FI, like Rick's Vortech making 400+whp, he saw a ~2hp difference between the two cats. Both cats are rated "High Flow" from Magnaflow, the manufacturer.
Local sale pending.
