Many Subaru owners want their turbo cars to spool up quicker and still deliver great horsepower and torque gains. With the new Agency Power equal length header this is absolutely possible.
By implementing the equal length tubing and merged collector, Agency Power is able to improve your turbo spool up by 300rpm. Because of the free flowing design of this header, you will see gains across the entire RPM range as exhaust flow is vastly improved. The construction of the equal length header features polished 304 stainless steel. The header has CNC machined 1/2 inch thick flanges and includes everything you need to bolt directly on to your Subaru turbo vehicle.
Because of the equal length design, this will cause you to lose the distinct Subaru engine sound for a smoother exhaust note.
