Engineered for maximum performance, the FMF Racing Factory 4.1 RCT Slip-On exhaust with titanium anodised finish and carbon fibre end cap introduces cutting-edge FMF Resonance Chamber Technology™ both inside and out. Its compact, forward-positioned design minimises susceptibility to crash damage while enhancing mass centralisation for sharper handling. Precision-constructed in Southern California using aerospace-grade titanium and a robust stainless steel midpipe, this slip-on offers substantial weight reduction and noticeable power gains across the RPM spectrum.
