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)

A: 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.

A: 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

A: 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.
