It will improve the breathing and clear up your exhaust path though. Interested to be the first to try it out on a Nismo Z?

First to try HFC's on a Nismo, or the ERZ HFC's specifically? Someone else with a Nismo has got to have HFC's already... I'm tempted to buy HFC's just for the sound, but I'm waiting on my coilovers and don't want to have too many mods in progress at the same time. Also, I couldn't really do a good dyno comparison since my car isn't past the engine break-in period.
