One of the most anticipated cars from Subaru is the 2011 STi’s return to a sedan form. Our customer took his STi sedan and added a few Agency Power parts to give his ride a boost in power.
The car came to us with the Agency Power catback exhaust, downpipe and intake already installed so we were unable to get a baseline. But after a custom tune on our Mustang II AWD dyno, the final numbers came in at 295 whp and 318 ft lbs of torque with about 18psi of boost. This is a great indicator that the 2011 STi will be tuner friendly and a true force on both the street and the track.
