The Akrapovic S-H4MET16-FDHLTA Evolution Exhaust System is engineered specifically for the 2021 Honda CRF450R and CRF450RX, making it an ideal upgrade for off-road enthusiasts seeking performance and durability in extreme conditions. This exhaust system is designed to fit within the limited space of the motorcycle, ensuring a seamless integration without compromising on performance.
Constructed from high-grade titanium alloys, the Akrapovic exhaust is 26.5% lighter than the stock exhaust, significantly reducing overall weight while maintaining strength. The varying thickness in the sections not only enhances protection but also contributes to the durability needed for rigorous off-road racing.
The muffler design maximizes the available space, allowing for improved sound suppression to meet FIM noise limits for competition use. This design also facilitates better exhaust flow, minimizing restrictions as gases exit the combustion chamber. The result is a deep, resonant sound that complements the single-cylinder engine's balanced pulse, enhancing the rider's experience.
Performance gains are notable, with an increase of +2.1 kW (approximately +2.8 HP) at 9,750 rpm and +1.8 Nm of torque at 9,460 rpm, as verified through in-house dyno testing against the stock exhaust system. These enhancements provide a more responsive throttle feel across the entire rev range, giving riders a greater sense of control.
The Evolution Line features a titanium header with an integrated resonance chamber that optimizes both performance and sound quality. Additionally, the exhaust is equipped with a newly designed titanium heat shield for added protection. Installation is straightforward, with a plug-and-play operation that requires no remapping.
