Exhaust Silencer FMF Factory 4.1 RCT — Suzuki RM-Z 450 2018–2026, titanium muffler, carbon, blue (4T)

Description

The FMF Factory 4.1 RCT is FMF's flagship four-stroke silencer. RCT (Resonance Chamber Technology) is a patented core shape that pulls the noise down while keeping the power up — so you can ride where the decibels get measured without giving up performance. Internal ducts in the chambers increase volume and improve flow, so power rises across the whole rev range. Factory Forward Engineering centralises mass, which helps handling and reduces crash damage. The rear end cap opens with four screws — you swap a tuning insert or spark arrestor without taking the silencer off. Works with the stock header or an FMF one. Fits: Suzuki RM-Z 450 (2018–2026). Specifications — muffler material: Titanium, end cap material: Carbon Fiber, muffler finish: Anodized, Blue. Spark arrestor included. QuietCore 94 dB insert included. Delivery 5–8 working days. SKU: 043365.
