0911 SUBARU WRX SEDAN STAINLESS STEEL 3IN HIGH FLOW CATBACK SYSTEM W/ VAREX MU

XForce offers a range of uniquely engineered and designed stainless steel bolt-on exhaust systems. These exhaust systems bolt directly to existing mounting points, making installation easy. They are built to perform well, with materials designed for longevity, and like all XForce exhaust systems, they look great! The unique header design increases power throughout the rev range while providing a great engine audio note. VAREX mufflers utilize patented technology to combine both the design technology of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary between the two. For higher sound levels, the exhaust flows are directed through the opening path and produce maximum power with a robust sound level (or the "sports car note") and near-zero resistance.
