Akrapovic S-H4MET16-FDHLTA Titanium Full Exhaust System Honda Crf450R-Rx 2021 - 2024

Tailor-made to fit the limited space available within the motorcycle, this system combines performance and durability for the extreme conditions and rigours of off-road racing. Constructed from lightweight, high-grade, premium titanium alloys, with multiple thicknesses in the sections to ensure perfect protection and to reduce overall weight, the system is 26.5% lighter than the stock exhaust. A new profiled surface influences the sound to meet FIM racing noise limits and adds strength and durability to the muffler while delivering a deep, full sound that embraces the balanced pulse of the single-cylinder engine. The muffler is as large as possible for the space available. This allows for greater acoustic quietness, which mitigates the impact on the natural environment, while facilitating a better flow of exhaust gases heading out of the combustion chamber with the least possible restrictions. The additional strength created by the design aids durability and provides greater resilience in the most demanding conditions. It offers increased response across the entire rev range and optimum feel when opening the throttle, giving the rider a great appreciation of control. Power and torque levels have been increased with an additional 2.1 kW (2.8 hp) at 9,750 rpm and 1.8 Nm at 9,460 rpm recorded on the in-house dyno in consecutive tests with a stock exhaust system. The Evolution Line (Titanium) exhaust has a special logo embossing technique on the surface for increased durability and a titanium header with an integrated resonance chamber for optimum performance and sound, which is covered by a newly designed titanium heat shield. It is a simple plug-and-play operation to install, with no remapping required. The exhaust system fits the Honda CRF 450 X version. FOR CLOSED COURSE COMPETITION USE ONLY. NOT FOR ROAD USE.
