The 2008 WRX Hatch Turboback is a complete exhaust solution from the turbo all the way to the muffler tip. The downpipe is TurboXS's 4.5 inch Cast bell mouth design which tapers smoothly down to 3 inches to connect to the TurboXS racepipe. Typical gains of adding race pipe are about 5-10 hp over a cat depending on the vehicles power package. The melodic boxer tones play through the 3 inch Cat-back which features a straight through muffler and a 4 inch slash cut tip. The muffler and tip look really nice exiting the back of your sleek 2008 WRX. The horsepower gains of the complete system are a 29 ft. lbs. and 30 whp gain over a stock 2008.
