BBK 2015-16 Ford Mustang GT Varitune Axle Back System (Cut & Clamp Direct Bolt On Design)

You get a full set of ceramic pads and slotted rotors in this kit, which means one box handles the whole brake job. This BBK Varitune axle back exhaust system is built for your 2015-2017 Ford Mustang GT, offering a way to really dial in the sound and performance of your V8. It replaces the factory mufflers and tips with a well-built system featuring BBK's patented adjustable power valve technology.

The real trick here is the Varitune muffler. Inside each muffler is a valve that you can adjust with a wrench from the outside. By moving this valve in or out, you change how much exhaust gas flows through the muffler's chambers. Push the valve out for a more aggressive, louder tone and maximum performance gains, or pull it in for a more subdued sound. Once you find the sweet spot, a locking nut keeps the valve right where you want it. The valves themselves are made from stainless steel to ensure they operate smoothly and last a long time. This system is constructed from 2-3/4 inch diameter 439 stainless steel muffler cans and 304 stainless steel tubing, all made in the USA, and it comes with 4-inch brushed stainless steel tips that are laser etched with the BBK logo for a sharp look.

Installation is designed to be straightforward, as this kit is a direct bolt-on replacement for your stock axle-back exhaust. It includes all the necessary hangers, hardware, and new clamps you'll need to get it installed. You can expect to personalize your Mustang's sound and power by 8-10 decibels and gain an estimated 10-15 horsepower with this system, depending on how you set the valves.
