BBK 2015-16 Mustang GT Varitune Complete Cat Back Exhaust System (Includes Resonator Delete X-Pipe)

What sets this system apart are the BBK Varitune mufflers. Inside each muffler is a patented adjustable power valve. You can actually tune the exhaust flow through the muffler's chambers using a wrench from the rear of the muffler. By moving the valve in or out, you can adjust the sound level, anywhere from a more mellow tone to a much more aggressive roar, and BBK claims this can change the sound level by 8-10 decibels. They also say you can gain 10-15 horsepower, which comes from the improved exhaust flow. The valves themselves are made from stainless steel for durability and smooth operation, and once you find the sound you like, a locking nut keeps it in place. The rest of the system is built with aluminized steel for good corrosion resistance, and it all bolts up directly to your factory connection points. It also includes 4-inch brushed stainless steel tips to give your Mustang a more muscular look.

This kit comes complete with the Varitune mufflers, a resonator delete X-pipe to further enhance flow and sound, all the necessary hardware, hangers, and clamps for installation. Just a heads-up, this system does not fit convertible models.
