Fi showed that when they dynod their HFC with a CBE on already and only got about 3 hp. So I think the first mod opens things up good and the following mods only net a few. Id love to see a dyno of all three without any other mods to see what they do and then add a mod, dyno again until you have all three on and see what the final results would be.

This. I'm wondering if putting HFC's on my Nismo will even be worth it. It is a lot less expensive and intrusive than intakes or replacing the full exhaust though.
