Akrapovic Evolution Line Full Exhaust System S-H4MET16-FDHLTA

Honda

• CRF450R/RX (2021-24)

Technical Specifications:

• Custom-built to fit the limited space available inside the motorcycle, this system combines performance and durability for the extreme conditions and rigors of off-road racing.
• Made from high-quality, lightweight titanium alloys, with differentiated thicknesses in different sections to ensure optimal protection and reduce overall weight, the exhaust system is 26.5% lighter than the stock exhaust. A new profiled surface influences the sound to comply with FIM racing noise limits, giving the muffler greater strength and durability, while also delivering a deep, full-bodied sound that enhances the harmony of the single-cylinder engine.
• The muffler is as large as possible given the available space. This allows for greater noise reduction, which mitigates the impact on the natural environment and simultaneously facilitates better exhaust gas flow, allowing them to exit the combustion chamber with the least possible restrictions. The increased robustness resulting from the design contributes to durability and offers greater resistance under the most demanding conditions. It offers a more immediate response across the rev range and an optimal feel when opening the throttle, giving the rider greater control. Power and torque levels have been increased, with an increase of 2.1 kW (2.8 hp) at 9,750 rpm and 1.8 Nm at 9,460 rpm, recorded on the internal dyno in comparison tests with a stock exhaust system.
• The Evolution Line (Titanium) exhaust features a special logo printing technique on the surface for increased durability and a titanium manifold with an integrated resonance chamber for optimal performance and sound, protected by a new titanium heat shield. Installation is simple and immediate (plug-and-play), with no remapping required.
• Exhaust system compatible with the Honda CRF 450 X version.
• FOR CLOSED CIRCUIT COMPETITION USE ONLY. NOT SUITABLE FOR ROAD USE.
