Introducing the all-new RS-9 Dual. The CRF's new dual-muffler configuration gave Yoshimura the opportunity to create an entirely new muffler built specifically for the dual-muffler CRFs. Yoshimura worked with top AMA Pro riders to achieve maximum performance and mass centralization, and to optimize rider usability. They achieved all this while maintaining AMA Regulation sound levels. The RS-9's uniquely sculpted carbon fiber end-caps feature a Tunable Insert System, so you can fine-tune power delivery and decibel levels to your specifications.

  • Parallelogram-shaped muffler.
  • Increased muffler volume over stock system, resulting in better throttle response and improved noise cancellation.
  • Lightweight muffler construction with carbon fiber end-cap.
  • CNC machined muffler bracket.
  • Reduced weight over O.E.M. system.
  • Vertical tail-pipe divider splits the exhaust gases more evenly, for smoother flow, which improves mid-top power and throttle response.
  • Titanium header and tail-pipe.
  • Note: Optional AMA Pro Sound Inserts are available separately.

Real Quality Exhaust!

Real quality exhaust! Fit perfectly and really unleashed the power. Weighs 2.8 pounds less than stock. However, doesn't come with spark arrestors or the other tuneable inserts. (not available at this time)

Generally when installing a full system you will need to re-program.

No, The Yoshimura RS-9D Exhaust Systems are intended for closed course use only, there is not a spark arrestor insert made for this exhaust. Actually most full carbon can's are not going to be Forest Service approved due to the fact that running a spark arrestor in a full carbon can is not recommended. When you run a spark arrestor in a full carbon fiber muffer the heat tends to build up and burn up the packing quickly. I would recommend looking at the FMF Factory 4.1 RCT Dual Exhaust with the Megabomb Header. The FMF exhaust would come with a Forrest Service Approved Spark Arrestor Insert.

Yes, The Yoshimura RS-9D Full System Dual Exhaust is the same for 2013 and 2014 Honda CRF450R's. The Yoshimura Part number for this specific exhaust for your CRF would be #225811H720. More information on this particular exhaust could be found here: http://www.yoshimura-rd.com/p-5057-rs-9-titaniumtitanium-full-system-dual.aspx

Are you able to run a spark arrestor?

There is not a Spark Arrestor insert that would work for this exhaust. Actually Yoshimura does not recommend that you run a spark arrestor in full carbon fiber cans as it decreases the packing life significantly which will also decrease the life of the Carbon Fiber. If you are looking to run a spark arrestor I would recommend looking for an exhaust that is constructed of titanium or aluminum.
