BBK Vari-Tune adjustable muffler is a one of kind muffler that gives back the control of the vehicle's sound and performance to the customer. There's nothing else like this on the market - go from loud to moderate in a matter of minutes.

BBK adjustable mufflers are available in popular sizes 2.5", 2.75", and 3", which means they'll fit most gas trucks and SUVs on the market today. The adjustable screw changes the exhaust flow in the muffler. When it's closed, the muffler performs as a three-chambered, creating a more moderate tone. When the adjustment screw is in the open position, the muffler becomes a straight through muffler, increasing the sound level as well as improving performance. All mufflers feature offset inlet and outlet.

So, if you're looking for a truly unique muffler that allows you to adjust the sound and performance of your ride, don't look any further than the BBK Vari-Tune adjustable muffler.
