FMF Racing Powercore 4

We installed FMF Racing's PowerCore 4 HEX Muffler and PowerBomb Header on our Ultimate Honda TRX450R Build.

FMF Racing's PowerCore 4 HEX Muffler weighs only 4.7 pounds and increases the horsepower and torque throughout the entire power curve producing a noticeable power increase that is useable and compatible with every style of riding. Aluminum construction and stainless steel Hi-Flo endcaps make for the perfect balance of performance and strength. Removable spark arrestor included. The Powercore4 retails for $329.99 and is available at FMFRacing.com.

FMF Racing's PowerBomb's Honda TRX450R header 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. The PowerBomb runs for $199.99 through FMFRacing.com.
