The HP varies with whatever header you plan on installing.Some companies can guarantee up to 25+ HP others (normally) around 10 to 15+ HP. Also the real question is; where do you want that HP to go to? The high end, mid range, or the low end? But don't just get a header, add the exhaust and the intake. Honda mathematics: Intake volume + headers + exhaust = HP
