The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity. Additionally, the PowerBomb is a pre-muffler of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). Designed for use with FMF mufflers and not guaranteed to fit other brands of mufflers. If you have a po box, please provide BOTH the po box and physical street address. Some items may have a slightly different appearance than what is shown in the picture.
