Yoshimura RS-9 Dual Full Exhaust System SS/SS/AL/CF for Honda CRF450R 2013

Features

• For closed course competition use only. Not intended for street use.Beginning with the header, a three-stage tapered design results in better power, better throttle response and usable power delivery. It's also spring-mounted for increased durability. The header flows seamlessly into a reconfigured midpipe, where the exhaust gases are separated to each muffler. Yoshimura's vertical divider splits the exhaust gases more evenly, for smoother flow, which improves mid- to top-power and throttle response. Divided exhaust gases then reach the new dual RS-9 mufflers. RS-9 mufflers have parallelogram-shaped bodies which increase muffler volume over the stock system, resulting in better throttle response and improved noise cancellation. The dual setup enabled Yoshimura to position the mufflers closer to the bike's center of gravity, resulting in better handling for the rider. An additional benefit of the mass centralization process was decreasing potential for muffler damage in the event of a crash. RS-9 not only makes more power and torque possible, but does it more quietly than single system. The uniquely sculpted carbon fiber end caps feature a tunable insert system, able to fine-tune power delivery and decibel levels to rider specifications. AMA Pro and Amateur sound legal out of box
