2011-2014 Mustang GT BBK Varitune Axle-Back Exhaust Kit (Stainless Steel) 41015

Adjustable Sound With BBK Axle-Back Exhaust

With all of the options available on the market these days, finding the perfect axle-back exhaust kit for your Mustang GT can be overwhelming to say the least, especially if you're looking for a very particular sound or volume. To help aid in that indecision, BBK Performance developed this Varitune Axle-Back Exhaust Kit (Stainless Steel) which offers the flexibility of an adjustable muffler. This unique technology allows you to easily adjust exhaust volume over a huge range, from a throaty race-quality roar to a quiet stock-sounding set up...giving you complete control over the sound of your Mustang's exhaust. The mufflers can easily be adjusted with a wrench once installed, allowing you to keep them nice and quiet in your neighborhood, but loud and proud out at the track or your local meetup. The driver and passenger side mufflers come with polished exhaust tips and was designed to bolt right in place of your stock axle-back exhausts without having to do any modifications.

Advanced Adjustable BBK Exhaust Design

BBK's Varitune Axle-Back with "Adjustable Power Valve" works by combining an adjustable valve with a unique "chambered" internal design that allows for up to 10 decibels worth of sound adjustment. When the adjustable valve is completely closed, the Varitunes function like a standard chambered muffler where exhaust gasses are forced through narrow slots in one chamber over to the opposing side which keeps overall volume down. When the valve is fully open, the muffler acts like a performance straight-through muffler and exhaust gasses pass through one tubular chamber and right out your exhaust tips with minimal deadening and sound loss. The Varitune system can be adjusted anywhere in-between to dial in the sound you need.
