Unique Tunable Design
This 2015-2017 Mustang GT Varitune Cat 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. Also included with each system is a pair of 4" polished high flow internal chambered exhaust tips for great looks and performance.

Customize Your Car's Sound
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.

Easy Installation
This BBK exhaust kit is designed to be a simple bolt-on. All you need is some basic hand tools and jack stands or a lift and you're good to go. Installation can typically be done in under an hour.
