By positioning this �Bomb�� at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! 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). On some models, you can choose between a moto or supercross version. The supercross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range.
