There is a current magazine out that did dyno runs on a g37. I believe they added intake, catback, hiflow cat, and the apexi voltage stabilizer (~$125). The total increase was 25-30whp. The increases overall were minimal for the voltage stabalizer (1-3whp depending on the rpm range), while a high flow cat gave the G a 14whp increase alone! I wouldn't trust the ebay brand because the wiring is probably weak. It's like using stereo/speaker wire in your engine bay for grounds.
