Race-bred titanium construction meets uncompromising durability. The Factory 4.1 RCT Exhaust System delivers peak horsepower and torque across the YZ450F powerband with a lightweight design that shaves rotational mass without sacrificing strength.
Forged titanium tubing resists heat degradation and corrosion. Anodized blue finish pairs aggressive looks with long-term color retention. Carbon fiber end cap adds premium aesthetics and functional weight savings at the rear of the system.
Precision-mandrel bent tubing optimizes exhaust scavenging for cleaner mid-range response and top-end pull. Direct bolt-on fitment—no modifications required. Dyno-tested for measurable gains on stock and modified motors.
Backed by Factory engineering. Built for riders who demand both speed and reliability.
