Ever wish your exhaust system were more like your stereo? If only there were an easy way to crank up the volume when you want to intimidate the competition—or dial it back when your neighbors start giving you the stink eye. The time has come for effortless exhaust tone tuning. Introducing the BBK Vari-Tune Adjustable Performance Muffler.
Optimized for both sound and speed, the BBK Vari-Tune Muffler is engineered to excite your eardrums and satisfy your lead foot. The built-in Vari-Tune technology lets you quickly adjust the chamber valve, controlling the growl up to 8 dB. Along with the sweet sound of a full-throated exhaust, these performance mufflers unleash hidden horsepower for power you’ll feel in the seat of your pants. And, if you're rolling with more than one BBK Vari-Tune Performance Muffler, you can set each one independently for less drone.
There's never a shortage of options with the BBK Vari-Tune Adjustable Muffler, you get to choose more than just the sound. These adjustable mufflers also come in your choice of metals: aluminized steel or stainless steel. Plus, they're available with varying inlets and outlets to fit a wide range of cars, trucks and SUVs. BBK also backs your Vari-Tune Muffler with a 1-year warranty.

My 2008 Bullitt ran 281 HP on the dyno with stock mufflers. The BBK 3101 install took about 2 hrs. We reused the hangers and tips off the original mufflers. With the adjusters closed we gained 4 HP over stock. Intermediate adjustments saw a couple of additional HP. Adjusted all the way out, we ran 291 HP @ 6100 RPM. Few power upgrades will give you that much bang for the buck. The mufflers are louder with a deeper sound than stock but do not drone at highway speed. I am very happy with them!
