Description
FMF Factory 4.1 RCT Titanium Slip-On Exhaust – KTM Optimized
Engineered for precision and power, the FMF Factory 4.1 RCT Titanium Slip-On exhaust delivers unmatched performance for off-road enthusiasts and competitive riders. Its proprietary Resonance Chamber Technology™ optimizes exhaust pulses for instant torque and sustained horsepower across the entire RPM band, ideal for motocross tracks or endurance trails.
Compact & Durable Design
Featuring a shortened muffler profile (compared to standard models), this exhaust resists crash damage while aligning with FMF’s Factory Forward Engineering—centralizing mass closer to the engine for improved balance and agility. Constructed entirely from aerospace-grade titanium alloys (exclusive proprietary blend), it withstands extreme temperatures and harsh conditions without compromising durability or adding bulk.
Key Innovations
– Rapid Tuning System (RTS): Swap muffler-end caps in seconds to adjust sound profiles or performance modes (race/quiet settings).
– 94dB Quiet Insert: Meets noise regulations for public trails while maintaining 95% of peak power output.
– Weight Advantage: Ultra-light at 4 lbs—shedding up to 30% weight vs. OEM steel systems for faster acceleration and handling.
Compatibility & Safety
Designed exclusively for KTM models (see Fitment Tab for header compatibility). Includes FMF-certified spark arrestor screen and carbon fiber end cap for premium aesthetics. Note: Intended for closed-course racing; not street-legal.
