FMF 041621 Factory RCT Titanium Full Exhaust System with MegaBomb Header - 4.1

The FMF Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology both internally and externally, delivering a complete performance exhaust solution for motocross and off-road riders. This system is constructed from only aerospace grade materials that meet FMF's exacting specifications and is manufactured 100% at their Southern California factory.

Key Features:

• Blue anodized titanium construction with carbon fiber end cap
• Includes titanium MegaBomb header for enhanced exhaust flow
• Shorter overall length that is less susceptible to crash damage and complementary to Factory Forward Engineering - moving the muffler closer to the motor to centralize mass
• Massive power gains throughout the RPM range
• Huge weight savings with new RTS (Rapid Tuning System)
• Includes 94dB quiet insert and spark arrestor screen insert
• Uses FMF's highest quality proprietary blend of alloy grade titanium

The patented header design allows exhaust gases to expand, cool and ramp back up at a higher velocity, resulting in torque gains typically associated with longer headers and the healthy over-rev of a short header. This is a closed course use only system.
