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!
