Features
4.1 RCT Muffler:
• Incorporates the latest in FMF Resonance Chamber Technology both internally and externally
• Shorter overall length that is less susceptible to crash damage and moves the muffler closer to the motor to centralize mass
• Massive Power gains throughout the RPM range
• Huge weight savings
• New RTS (Rapid Tuning System)
• New rear endcap
• Redesigned canister
MegaBomb Header:
• Produces long header torque and short header over-rev
• The larger midsection creates a larger surface area for sound dissipation to reduce the sound output by as much as 1.5dB
• Increases output from stock motor as much as 3 HP alone
• Constructed out of premium American stainless steel material
• Designed with a unique midsection, comparable to the PowerBomb header, that provides improved power across the power range
• The unique design of the MegaBomb header allows for better low end torque similar to a long header while also improving top end power much like a short header
• Although the MegaBomb header offers the advantages of a long header, the design of the MegaBomb header reduces the length and the chances of getting in the way or suffering damage
