Evolution Line exhaust system - EVO titanium CRF450R/450RX

Tailor-made for the bike's limited space, this system combines performance and durability for extreme conditions and off-road demands
Made from premium, lightweight, high-quality titanium alloys, with different thicknesses depending on the section for maximum protection and weight reduction; the system is 26.5% lighter than the original exhaust
The profiled surface tunes the sound to comply with FIM competition noise limits, adds strength and durability to the silencer and provides a deep, full sound that highlights the balanced pulse of the single-cylinder engine
The silencer is the largest possible for the space available, allowing greater sound attenuation, reducing environmental impact and facilitating better exhaust gas flow from the combustion chamber with the least possible restriction.
The design delivers greater strength, durability and robustness in the most demanding conditions.
Offers improved response across the rev range and an optimal feeling when opening the throttle, giving the rider great control
Power and torque increase: +1.8 kW (2.5 HP) at 10,300 rpm and +1.5 Nm at 7,900 rpm, measured on the dyno against the original exhaust.
The Evolution Line (Titanium) exhaust uses a special technique to engrave the logo on the surface for greater durability and features a titanium manifold with integrated resonance chamber for optimal performance and sound, covered with a new titanium heat shield.
Easy plug-n-play installation with no need to remap the injection
For closed-circuit competition use only; road use prohibited.
