If you’re like the many who are having trouble finding a fitting exhaust note for your Mustang without shelling out a ton of cash to test different parts or sacrificing performance, then worry not. Varitune is here and is revolutionizing how your Mustang’s exhaust sounds and operates.
BBK Varitune is Revolutionizing Mustang Exhaust Systems
Now there’s a new way to fine-tune your Mustang’s exhaust, courtesy of BBK. If you love it loud, BBK’s Varitune adjustable performance mufflers let you completely open the “Adjustable Power Valve,” changing the muffler from a three chambered exhaust to one for a screaming setup that will put down more rear wheel horsepower.
If you need to tone it down a bit for the sake of the neighbor’s sanity, just close the adjustable port. It’s that simple and can be done easily from outside the car with no more effort than is required to unscrew a bolt.
Installation: BBK’s Varitune exhaust mufflers and axleback systems are a direct bolt-on replacement for your stock setup and, depending on how far you open the valve, can vary your sound level from 8-10 decibels. Installation is no different than your typical replacement muffler or axleback and is designed to allow you easy access to adjust to your preferred sound and performance level.
What performance gains will a Mustang see from a Varitune setup?
According to an article in 5.0 Mustang & Super Fords Magazine that detailed a dyno tested BBK Varitune muffler setup on an otherwise stock 2012 Mustang GT, an increase of 7.3RWHP and 6.39 torque was seen over the stock mufflers. The chambers were fully open to see this increase, but there was still a power boost just by simply installing Varitune mufflers and leaving the valve closed.
All-in-all, Varitune is a revolutionary system giving Mustang owners the first and only way to change exhaust sound and performance levels in a matter of minutes.
