XForce ES-FM10-VMK-ABS Stainless Steel Axle-Back Exhaust System with Dual Rear Varex Mufflers for Ford Mustang GT 2005-2010

VAREX™ mufflers utilize our patented technology to combine both the design 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 be-tween the two. For higher sound level, the exhaust flows are directed through the opening path and produces maximum power with a robust sound level (or the “sports car note”) and near-zero resistance. For lower sound level, the exhaust flows are directed through the chambered path (similar design with the stock muffler) and produces minimum sound level that gives you the best in-car comfort. Angle of the valve is also controllable, which can be adjusted to stop at various points between sports mode and silence mode. This gives you further freedom to set the optimal sound level according to your desired preference. VAREX™ motor and gear sets are located on the top of the muffler, they work as an integrated unit to drive the butterfly valve open and close. Easy Installation, no hard-wiring required (in-car 12V socket included) for plug and play functionality. Stylish remote key fob included.
