XFORCE 2012 ON WRX HEADER
XFORCE have developed a Tri Y header with a slight variation In tube length to help maximise the spread of power and torque gained with this bolt on upgrade for the 2012 onward WRX.(Not STI)
Our tube design coupled to the smooth collector was capable of an producing an extra 12-15Kw of power and 25-28nm of torque on our test vehicles.
The header is a fantastic bang for buck addition to the WRX, it does not require an ECU tune post fitment and Is the perfect addition to a standard Vehicle or those already fitted with turbo back systems.
