One-of-a-Kind Adjustable Axle Back
The BBK Varitune Axle Back Exhaust Kit for 2011-2014 Mustang 5.0L offers full tuning ability with BBK’s patented adjustable power valve. That’s right, these unique systems come complete with two patented tunable Varitune performance mufflers engineered with high-flow, direct fit stainless steel 2-3/4″ tubing and hardware for an easy bolt on installation. Each system also includes a pair of stylish 4″ stainless tips to deliver good looks in addition to maximum performance.
Adjustable Mufflers?
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.
