The Turbo XS 2005-2009 Legacy GT Midpipe & Y-Pipe is finally here. This is the perfect upgrade to your exhaust, the benefit of reducing backpressure on turbocharged cars will net huge power gains. In life good things come with the bad, in this case there are none. A slight increase in exhaust tone. The 3 inch 304 stainless midpipe was designed and best used with a 3 inch downpipe, but can install to a stock midpipe. The y-pipe reduces to 2.5 inches to mate to your stock muffler.
