AKRAPOVIČ SUPPORTS THE HONDA CRF450R / RX
A krapovič has launched the Evolution Line titanium exhaust system for the Honda CRF450R / RX , featuring an innovative design to stand up to the demands of offroad racing . This tailor-made exhaust fits the limited space available within the body of the CRF450 and has been developed to produce a system that combines performance and durability for extreme conditions and the rigours of racing with good looks . Constructed from lightweight high-grade titanium , the all-new Evolution Line exhaust system has a new profiled surface that adds strength and durability to the muffler . It has been made to disrupt the sound patterns and add to the dampening effect to bring the noise output within the strict FIM levels while also delivering a deep , full sound . Akrapovič says it has created a muffler that is the largest possible for the space available , allowing for increased sound silencing . The larger muffler also facilitates improved flow for the exhaust gases to make their way
from the combustion chamber with as few restrictions as possible , increasing operational performance . The added strength from the design also aids in the harsh environments of motocross and enduro , where vibrations , high peak temperatures , stones , sand , mud , and crashes are the norm . The Evolution Line ( Titanium ) exhaust system incorporates different thicknesses of premium titanium alloys , with thicker levels used to prevent damage in exposed areas and thinner parts in other sections to reduce overall weight . This has created a system that is 26.5 % lighter than the stock exhaust . A new specially designed and shaped resonant chamber optimises the power and sound of the system , engine response is heightened through the entire rev range . Power and torque levels have been increased with an extra 2.1kW ( 2.8hp ) at 9750 rpm and 1.8Nm at 9460rpm . It is a simple plug-and-play operation to install , with no remapping needed .
