System Builder
We have a variety of pre-configured systems to choose from, but not every option is sold as a system. If you want a little more flexibility, use this tool to build a system for your bike. First, select your bike make model and year, then select a header and a muffler. Once you're happy with your choices, click on the "Buy" button to add the system components to your cart.

Selected Header:
S/S Powerbomb Header
POLARIS OUTLAW 525 IRS'07 STAINLESS STEEL POWERBOMB HEADER
Retail: $299.99
Your Price: $239.99
Item ID: 045172
Type: Header
Header Const: Stainless Steel
Header Type: PowerBomb
The redesigned PowerBomb is a four-stroke header that incorporates FMF's 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 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.
