Akrapovic Evolution Line Exhaust System — Titanium — CRF450R/CRF450RX

Akrapovic · #1820-2089 · Full-Systems / Exhaust

Tailor-made to fit the limited space available within the motorcycle, this system combines performance and durability for extreme conditions and the rigors of off-road racing
Constructed from lightweight, high-grade, premium titanium alloys, with different thickness in the sections to ensure perfect protection and to reduce overall weight, the system is 26.5% lighter than the stock exhaust
Profiled surface influences the sound to meet the FIM noise limits for competition, and it adds strength and durability to the muffler while delivering a deep, full sound that embraces the balanced pulse of the single-cylinder engine
Muffler is the largest possible for the space available, this allows increased sound silencing, which mitigates the impact on the natural environment while also facilitating improved flow for the exhaust gases to make their way from the combustion chamber with as few restrictions as possible
Added strength created by the design aids durability and provides enhanced resilience in the most demanding conditions
