The 57 series uses plastic tubing and the 77 series is metal. K&N claims the 57 series actually makes a little more power than than the metal 77 series and it's a little cheaper than the 77 series so I'm not sure why they would lie about that but I could be wrong either way i don't think it would be a noticeable difference in seat of your pants power. Usually a metal tubed intake will sound a little louder than the plastic ones also.
