To build on to our already thriving 2008 Subaru WRX, Agency Power completed their prototype downpipe to make a complete 3 inch Turboback exhaust system. The all stainless bellmouth downpipe helped the WRX breathe a ton more. Reaching a gain of 33 Wheel Horsepower and 45 ft/lbs of torque when pair with our catback exhaust and crank pulley. The downpipe is slightly different from the WRX/STI GD Chassis. Only a few mods were needed to be done.
