...DC Sports : 4-2-1 - TEST SET 01The first of the DC headers - the tri-y configuration - also showed a large increase in power in the 3000-4700 range, again with peak gains of about 12-14hp. Like the 5Zigen header, the DC Sports unit smoothed the powerband and removed the dip in the "street driving" range below VTEC.

although considering that the motor is different im hoping to see some low end improvments which this design is known for..























Red is baseline and Blue is with the DC Sports Header
