Q: I have the 2014 slip on Yosh system and will it match with the 2015?
1 year 4 months ago
I have the RS-9D slip -on system on my 2014 crf 450R. and I plan on getting the 2015 crf 450R. Will this slip-on system, I currently have on my bike match on the 2015 as well? I can't seem to find someone in the know.

A: No, the Yoshimura RS-9D Slip-On Exhaust would be different on the 2015 CRF450R than the 2014 .

I have a 2014 crf250r and I was wondering if I would have to remap my bike if I got the yoshimura rs-d9.

A: Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. If your bike is currently running properly, likely you will not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .

Q: Rs9 header pipe?
2 years 2 months ago
I have a 2013 Crf 450, also have a spare yoshi ss header spare from my old 2010 bike. This fits directly on to stock system, so in theory I only need this slipons and not the full system? Any thoughts on this?

A: The head pipe is different from the 2010 and 2013 Honda CRF450R so fitment is not guaranteed. The Yoshimura RS-9D Slip-On Exhaust - Dual is made to fit the stock (OEM) head pipe so you will need to get the full system, or use your stock head pipe.

Q: Would the Yoshimura RS-9D work with an FMF MegaBomb titanium header on my 2013 Honda CRF450R?

A: No those will not work together.

The FMF Mega Bomb Header is made specifically to fit only FMF exhaust systems, FMF slip on Mufflers or the OEM Muffler.

The Yoshimura slip-on would just fit onto the OEM head pipe.

I would recommend looking at the Yoshimura RS-9D Full Exhaust system if you were looking for the headpipe and these mufflers.
Q: Does the Yoshimura RS-9D slip on or full exhaust system come with removable spark arresters?

A: Currently Yoshimura does not offer the RS-9d with a spark arrestor insert. I also checked and they do not show one to purchase seperately.
