Question asked by tony

Question: I'm not sure what FMF pipe I have because the branding has been removed, it's fitted to my KLR650 and the pipe opening is 40mm, it has a hole in the same place as this insert does. Will it fit?

Question answered 1 year 5 months ago
Answer: If there is any type of serial number, usually on the inside of the pipe towards the exhaust port, you can contact FMF directly to find out which canister you have.

Question answered 1 year 5 months ago
Answer: The slip-on mufflers recommended for the KLR650 are the Powercore 4, part number 042319, and the Quietcore 4, part number 04321.
It would be best to call FMF at (310) 631-4363 to describe the full details of your muffler, and determine which spark arrestor is correct.
