BBK Varitune Cat Back Exhaust
Give your S550 adjustable sound and power with BBK's all new 2015-2017 Mustang GT Varitune Catback exhaust kit! BBK's patented design features an adjustable exhaust chamber that allows you to adjust sound and power with a few turns of the wrench. The valve opens and closes to the point you desire and then is locked in place with the jam nut. The full range of adjustment provides an 8 to 10 decibel sound increase while dyno testing has shown a consistent 10-15 horsepower increase over stock.
BBK's Varitune Catback exhaust is constructed with 304 series stainless steel that will hold up to the harsh elements and road debris. Utilizing an X-crossover design, your factory resonator is deleted to maximize exhaust flow. The adjustable chamber is reached at the back of the muffler for easy accessibility and adjustment. 4" polished stainless steel tips finish this kit off for a look that can't be beat! BBK constructs and manufactures this exhaust in the USA for the ultimate quality and performance!
