FMF Factory 4.1 RCT Slip-On Exhaust — Suzuki RM-Z450 2018–2026

A straightforward way to pick up power and shed weight — bolts to your stock or FMF header and delivers the throttle response this platform is capable of.

Fits: Suzuki RM-Z450 2018–2026.

Why riders pick it:

• RCT (Resonance Chamber Technology) tuning inside and out for a stronger pull through the midrange
• Aerospace-grade titanium or aluminum construction for a real weight cut over stock
• Shorter overall length keeps mass centralized and reduces exposure to crash damage
• Direct bolt-on installation, no tuning required

⚠️ For closed-course competition / off-road use only — not legal for street use in some states. Confirm your local regulations.
