Hi I have been searching but not finding much info probably because of the bikes being new. Mine is still on order but trying to figure out what my exhaust options are. Does anyone know of a FMF pipe that will fit the new 300 model? So far I have seen you can get a Delkevic which has mixed reviews and some posts on here of it being way too loud. Also I found a yoshimura but the price is really high. I see on the Delkevic site that theirs fits KLX250 from 2009-2019 and KLX300 2020-2021 so I figured a FMF from a 250 in those years should fit but checking pipes in those years on the FMF site shows different part numbers within those years.
Also I know the 2 pipes mentioned come with a spot to put in the o2 sensor and fmf probably does not but I was looking at getting EJK fuel tuner that comes with the o2 bypass anyway so that wouldn't matter.

So does anyone know if a fmf will fit and what year or part number I would need. Any info would be great. Thanks

 

The 2021's are so new Kawasaki doesn't even have online operator manuals for them. As far as I know the newer 250 and 300 bikes are identical except for a larger bore, piston, and rod bearings. There is almost no aftermarket part information, however this should change within the year.
