Unfortunately the standard Subaru WRX exhaust setup is quite restrictive to pass mass production emissions and sound legalities. Unequal length headers in our 4-2-1 configuration are slightly lighter than equal length, and are proven to increase efficiency and power, bringing boost on 200-300rpm earlier due to it's shorter runners.

Un-equal length ensures that beautiful boxer rumble is maintained!

Header Specifications

• High flowing 4 into 2 into 1 unequal length design for the best sound possible (typical boxer note)
