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!
