This 2015-2017 Mustang GT Varitune axle back exhaust kit offers full tunability with BBK's patented adjustable power valve. That's right, these systems come complete with two patented tunable Varitune performance mufflers engineered with the high flow direct fit tubing and hardware for a true bolt on installation for your S550 Mustang. Also included with each system is a pair of 4" Brushed Stainless exhaust tips for great looks and performance.
These American designed and built performance mufflers are the first of their kind in the aftermarket fully adjustable performance mufflers that can be adjusted for sound and horsepower by simply moving the adjustment screw in or out from underneath the car! BBK Varitune performance mufflers utilize a unique internal power valve. When in the closed position the valve blocks the exhaust flow, forcing it through all three chambers of the muffler for a classic mellow sound. When in the open position, the valve opens the exhaust flow allowing it to take the path of least resistance, acting more like a straight-through muffler for an aggressive throaty exhaust note.
Note: Only for coupe's will not work with convertible
