Adjust Sound To Your Liking!
This 2015-2017 Mustang GT Varitune Axle Back Exhaust Kit offers true full tune-ability 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. This kit uses high quality 304 stainless steel tubing and extremely durable 439 stainless steel mufflers for long lasting performance.

How Does It Work?
BBK Varitune mufflers feature an internal adjustment valve. When the valve is closed it blocks exhaust flow, forcing it through all three chambers of the muffler for a deep mellow sound. When the valve is open the exhaust takes the path of least resistance, making it more like a one chamber muffler for an aggressive, throaty exhaust note.

Great Looking
Also included with each system is a pair of all new 4" polished high flow internal chamber exhaust tips for maximum looks and performance. Note: factory midpipe requires minor cutting for installation.
