Exhaust
The Stainless Steel PowerBomb™ is a four-stroke header
that incorporates the patented PowerBomb™ module at a
precise location in the initial stage of the header. By positioning
this “Bomb” at a key point in the system, increased
performance and fl ow are achieved through the expansion
and contraction of exhaust sonics through the system. The
result is a fl ow 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 Power-
Bomb™ is a “pre-muffl er” of sorts, which helps to lower
the ATV’s sound output by providing more sound absorbing
surface area for the sound medium (exhaust gases). The
PowerBomb™ provides power focused in the mid to upper
rpm range.Note: All ’06 and later Sport ATV models are regulated by the EPA. Because this accessory affects emissions using it constitutes tampering punishable by law unless the vehicle
is only used in closed-course competition.
Note: This performance accessory does not meet California standards for off-road recreational vehicle usage regardless of model year.
