Here we have a 2011 Subaru STi that was custom tuned by TurboTek with just a turboback exhaust, AEM cold air intake and a 3-Port EBCS. With a stock STi making around 230WHP this car made a healthy ~50WHP gain from the exhaust and tuning alone. We typically always recommend a J-pipe or Downpipe as a starting point for making power on forced induction Subarus as not only do they offer considerable value, but is an inherent restriction on the exhaust side known to cause heat back up and loss of performance!
