FMF 4.1 RCT Slip-On Exhaust for KTM – Aluminum with Stainless Mid Pipe

FMF Factory 4.1 RCT Slip-On Exhaust for KTM

Elevate your off-road dominance with FMF’s precision-engineered slip-on exhaust—crafted exclusively for KTM riders tackling motocross tracks or closed-course competitions. Featuring groundbreaking Resonance Chamber Technology™ internally and externally, this system optimizes exhaust flow while shortening overall length to minimize crash damage risks during aggressive riding sessions.

Performance Redefined:
– Unrivaled Power Gains: Boost torque and horsepower across low-to-high RPMs—ideal for explosive acceleration out of corners or hill climbs.
– Weight Revolution: At just 7.1 lbs., shed significant mass versus stock systems—enhancing agility on technical trails or timed laps.
– Rapid Tuning System (RTS): Swap included inserts (<94dB quiet core/spark arrestor) in seconds—no tools needed—to adapt sound levels between practice sessions and regulated races.

Premium Durability Meets Innovation:
Constructed from aerospace-grade aluminum paired with corrosion-resistant stainless steel mid-pipes—all hand-built in California—to withstand punishing jumps and roost impacts. The natural finish with carbon end cap resists discoloration under extreme heat while centralizing mass near your engine via Forward Engineering design—sharpening bike balance through whoops or berms.

Ideal For:
– Motocross/enduro athletes seeking competitive edges
– Closed-course environments requiring spark arrestors
– Riders prioritizing weight reduction without sacrificing durability

Dominate dirt circuits confidently—where every ounce shaved translates to faster lap times and relentless control under throttle demand.
