FMF - 045714 - Factory 4.1 RCT Slip-On Muffler - '26 Ducati Desmo450
Sharing the same Resonance Chamber Technology and aerospace-grade construction as FMF's other Factory 4.1 RCT slip-ons, this version brings a shorter, crash-resistant design and centralized mass to a second '26 Ducati fitment, complementing Factory Forward Engineering principles. Manufactured 100% at the Southern California factory for riders who want FMF's flagship slip-on performance. That direct-fit approach carries through the whole LeoVince slip-on range, so the swap stays a straightforward afternoon job rather than a shop visit.
